The technical FIELD

[0002] the Invention generally relates to systems and methods for stabilization of the power provided by the energy source, and more specifically to systems and methods use different types of devices, energy storage (batteries) for sample storage and return of energy provided by energy sources, including renewable and non-renewable energy sources.

BACKGROUND of INVENTION

[0003] with the growth of the world population, the demand for electric energy will also increase. Fossil fuels (e.g. coal, oil and natural gas) have long been used as sources of energy in power plants. Burning fossil fuels causes air pollution, for example, carbon dioxide. These emissions have an adverse impact on the environment and can contribute to climate change. To reduce the degree of air pollution in some countries have enacted laws that restrict the permissible levels of emissions into the air of pollutants. These laws in the General case, the AE increase the cost of generating electricity from fossil fuels. Deposits of fossil fuels around the world are being depleted, as it does not recharge, commensurate with the consumption of Access to fossil fuels often depends on the political and economic situation. These factors jointly determine the rising and volatile price of energy derived from fossil fuels.

[0004] One of the solutions to the problems of environmental pollution in obtaining energy from fossil fuels, reducing their stocks in the fields, rising prices for fossil fuels and their volatility, as well as the relevant legislation is used to produce electrical energy from other sources, such as renewable energy. Renewable sources such as wind, solar and geothermal sources, currently used on an industrial basis, and the cost of electricity derived from such sources as a whole is reduced, as they are becoming more common, and with the improvement of appropriate technologies extract energy. Renewable energy potentially provide a solution to problems related to energy prices, availability, and environmental pollution that are relevant for energy from fossil fuels.

[0005] One drawback associated with voso the renewable energy sources, is that to receive energy from them can be influenced by factors that cannot be influenced by the operator, such as darkness, the wind or bad weather. For example, the sun does not Shine every day all day, and the wind does not blow steadily all day. Therefore, solar cells and wind turbines are not able to provide day-to-day steady stream of energy. However, it is desirable that the output power of these energy source was more or less stable. On the other hand the energy sources that use fossil fuels, such as gas turbine generators, are characterized by maximum efficiency is reached when the power output level determined by the design of the generator, so that it is desirable that the generator worked with a specific power output corresponding to its maximum efficiency. However, energy requirements may substantially change. Thus, there is a need for a system with an extended range of power values provided by the source to the load.

BRIEF description of the INVENTION

[0006] the present invention proposes a method of stabilizing the power provided to the load source of energy. In this way, when the power produced by the energy source exceeds the current demand of the load capacity, the excess energy is Oia is accumulated in the first accumulator, while the amount of energy in the battery reaches a first maximum level. In the second accumulator accumulates the energy produced by the energy source, when it exceeds the current demand of the load power, and when the amount of energy in the first battery is located on the first maximum level, while the amount of energy in the second battery reaches a second maximum level. In one of the embodiments of the invention, the stabilization of the power provided to the load by the energy source includes providing energy from the first battery to the load when the current demand of the load power exceeds the power provided by the energy source, while the amount of energy in the first battery reaches the first minimum level. If the amount of energy in the first battery is located on the first minimum level, and the current demand of the load power exceeds the power provided by the energy source, is used to supply energy to the load from the second battery while the amount of energy in the second battery reaches a second minimum level.

[0007] the invention also proposes a system for providing power to the load. The system contains an energy source, a first battery, a second battery and controllerpath energy. The energy source provides power, and the first and second batteries selectively storing energy received from an energy source, and selectively give it to the load. The flow controller power device power control, the control device of the first energy level, the control device of the second energy level, the energy Converter and the controller. The device power control controls the difference between the power provided by the energy source, and the current demand of the load power and generates a signal power that contains the specified difference. The control device of the first energy level monitors the energy level of the first battery and provides the signal of the first energy level contains the amount of energy in the first battery. The control device of the second energy level monitors the energy level of the second battery and provides the signal to the second energy level contains the amount of energy in the second battery. The power Converter responds to the signal accumulation coming from the controller, to selectively convert the energy source into energy for the first and/or second battery and signal switching coming from the controller to send the converted energy in the first and/or second battery is op. The controller determines the signal power that the power provided by the energy source exceeds the current demand of the load power, and provides the signal accumulation in the power Converter, so that the energy provided by the energy source, which exceeds the requirement of the load, will be accumulated in the first accumulator, until the signal of the first level of energy will not show that the amount of energy in the first battery has reached the first maximum level. If the signal of the first level of energy shows that the amount of energy in the first battery has reached the first maximum level, the controller changes the signal switching so that the energy Converter directed energy higher than the current demand of the load, the second battery until the signal of the second energy level will not show that the amount of energy in the second battery has reached the second maximum level.

[0006] the present invention also proposes another method of stabilizing the power provided to the load source of energy. In this way, when the power produced by the energy source exceeds the current demand of the load power during the first specified time interval, the excess energy is accumulated in the first accumulator, while the number of ene the GII in the battery reaches a first maximum level. In the second accumulator accumulates the energy produced by the energy source, when it exceeds the current demand of the load power, and when she continues to exceed demand load in power after the first specified time interval, or when the amount of energy in the first battery has reached the first maximum level, while the amount of energy in the second battery reaches a second maximum level. In one of the embodiments of the invention, the stabilization of the power provided to the load by the energy source includes providing energy from the first battery to the load during a second specified time interval after the current demand of the load power exceeds the power provided by the energy source, while the amount of energy in the first battery reaches the first minimum level. The power supply to the load from the second battery is when the current demand of the load power exceeds the power provided by the energy source, after a second specified time interval, or when the amount of energy in the first battery reaches the first maximum level, while the amount of energy in the second battery reaches a second minimum level.

[0009] In the image the attachment also serves another system provide the power in the load. The system contains an energy source, a first battery, a second battery and controller energy flows. The energy source provides power, and the first and second batteries selectively storing energy received from an energy source, and selectively give it to the load. The flow controller power device power control, the control device of the first energy level, the control device of the second energy level, the energy Converter and the controller. The device power control controls the difference between the power provided by the energy source, and the current demand of the load power and generates a signal power that contains the specified difference. The control device of the first energy level monitors the energy level of the first battery and provides the signal of the first energy level contains the amount of energy in the first battery. The control device of the second energy level monitors the energy level of the second battery and provides the signal to the second energy level contains the amount of energy in the second battery. The power Converter responds to the signal accumulation coming from the controller, to selectively convert the energy source to the energy of the first and/or second battery and signal switching coming from the controller, for sending the converted energy in the first and/or second battery. The controller determines the signal power that the power provided by the energy source exceeds the current demand of the load power, and provides the signal accumulation in the power Converter, so that the energy provided by the energy source, which exceeds the requirement of the load, will be accumulated in the first accumulator during the first specified time interval, until the signal of the first level of energy will not show that the amount of energy in the first battery has reached the first maximum level. If the signal of the first level of energy shows that the amount of energy in the first battery has reached the first maximum level, or power provided by the energy source, continues to exceed the current demand of the load in power after the first specified time interval, the controller changes the signal switching, so that the energy Converter directed energy higher than the current demand of the load, the second battery until the signal of the second energy level will not show that the amount of energy in the second battery has reached the second maximum level.

[0010] the present invention proposes another way of stabilizing power, PR is th in load energy source. When the power provided by the energy source exceeds the current demand of the load power is the accumulation of this excess energy in the first battery to a threshold rate of accumulation of energy from the first battery. If the energy source provides power that exceeds the amount of the current needs of the load power and the threshold value of the rate of accumulation of energy from the first battery, the excess energy is accumulated in the second accumulator. In one variation of the supplied energy from the first battery to the load when the current demand of the load power exceeds the power provided by the energy source, up to a threshold speed of discharge of the first battery. The power supply to the load from the second battery is when the current demand of the load power exceeds the amount of power provided by the energy source, and the threshold value of the speed of discharge of the first battery to a threshold speed of discharge of the second battery.

[0011] the present invention features another method of stabilizing the power provided to the load source of energy. When the power provided by the energy source exceeds the current demand of the load power, done which is the accumulation of this excess energy in the first battery, while power higher than the current demand of the load capacity does not exceed the threshold rate of accumulation of energy from the first battery. If the energy generated by the energy source exceeds the current demand of the load, it will be accumulated in the second battery if the power is higher than the current demand of the load power exceeds a threshold rate of accumulation of energy from the first battery. In one embodiment, the power supply from the first battery to the load occurs when the current demand of the load power exceeds the power provided by the energy source, and the difference between the current demand of the load power and the power provided by the energy source is less than the threshold speed of discharge of the first battery. The power supply to the load from the second battery is in the case, when the difference between the current demand of the load power and the power provided by the energy source exceeds a threshold speed of discharge of the first battery.

DETAILED description of the INVENTION

[0028] the Present description in no way should be construed as limiting its scope or application. The description below is intended to clear illustrations of various embodiments of the invention. As will become clear in the ways, structures, devices, systems, components, and compositions described in these embodiments may be made of various modifications without going beyond the scope and essence of the invention.

[0029] the Term "renewable energy"used in the present description, refers to the energy, which is obtained from natural sources that are not depleted when the extraction of this energy. Example and renewable energy sources are wind, the sun, the sources of hydropower, biomass and geothermal sources. As you will see from the following detailed description, the present invention can take different systems and ways of integrating renewable energy sources into existing electrical systems.

[0030] Various embodiments of the invention include devices for fast and accurate fault renewable source or lines of energy transfer to prevent a breach of electricity supply to consumers or mitigate the consequences of such violation. For optimal control, selection, switching, synchronization, and other functions necessary to select and use one of several available various batteries to supply energy to the consumer can be used to measure the physical characteristics and methods of probabilistic and/or adaptive management. For example, can be measured the voltage on the battery to determine the state of charge or the amount of energy in the battery. In addition, to determine the state of charge or the amount of energy in the battery can be used several different physical parameters such as temperature, limiting the number of cycles of charge-discharge and voltage.

[0031] the Term hybrid system energy storage", as used in the present description, refers to one or more of the batteries connected to each other (for example, to a group of batteries connected in series or in parallel), which accumulate energy in various forms and in various ways for its eventual release. Examples of batteries that are suitable for use in hybrid devices, energy storage, include electrochemical cells, batteries, fuel cells, capacitors, tanks of compressed air, flywheels, pumped storage systems, electrochemical elements with the pumping of the electrolyte flow batteries), thermal accumulator systems and similar devices. The person skilled in the art will understand that batteries of different types have different characteristics, suitable for the formation of hybrid energy storage systems, made up of a group of such batteries. For example, a lithium or lithium-ion batteries are relatively expensive, although characterized by a relatively high energy density and have a great life. Similarly, flywheels typically have a long life, but are characterized by a relatively high self-discharge rate. On the contrary, opposite the lead-acid batteries have a relatively low unit cost (the cost of the TB unit charge), however, are characterized by low energy density and have a shorter lifetime. Sodium-sulfur batteries are characterized by a good balance between energy density and lifetime. When designing a hybrid system energy storage available batteries can be combined in different ratios to achieve the objectives of such a hybrid system within the constraints defined by the location of the system and its intended use.

[0032] some hybrid devices, energy storage may be limited by the location system. For example, compressed air usually requires a large caves or other underground cavities for storage of compressed air, while for pumped storage systems require mountains, hills, dams or similar elevation to the use of mass and gravity for energy storage. Other hybrid devices energy storage can be quite compact. For example, electrochemical cells, batteries, flywheels and fuel cells can be mounted on the truck for quick installation in almost any location.

[0033] In accordance with various embodiment of the invention the hybrid system energy storage consist of parts, sections or individual batteries, characterized wusasa different energy densities. For some hybrid energy storage systems energy density is the ratio of energy-capacity-to-weight system. Other hybrid system energy storage is better characterized by the ratio of the energy capacity to the volume of the system. Both definitions are effective for determining the density of the accumulated energy in a hybrid system.

[0034] In some embodiments, the hybrid system energy storage may contain additional parts, sections or separate batteries with different possibilities for energy storage. The term "capacity" refers to the amount of energy that can be accumulated in a battery or energy storage. The capacity and density of the accumulated energy can be largely determine how much energy can be obtained from some of the hybrid system energy storage for a given time interval.

[0035] the Power consumed by the load at certain time intervals is determined by several factors. For example, for a residential building electrical power consumption may vary during the daytime, but at night it drops, and changes may be insignificant. Similarly, a manufacturing plant may require significantly more electrical energy than the dwelling house, and power consumption may be relatively constant throughout the day. In addition, the use of a computer or cell phone may require smaller quantities of electricity and for shorter periods of time. Graph of power or the amount of electricity consumed some load of time specified in the present description as the profile of the expected consumption of the power load.

[0036] Used in the present description, the term "energy" is defined as the product of power and time. Optimization of the hybrid system energy storage for use with a source of energy may depend on the physical characteristics and applications of load, including (without limitation) the profile of the expected power consumption, energy density in such a hybrid system, the location of the energy source, type of energy source, the location of the hybrid system and its transportation.

[0037] As shown in figure 1, the system 102 renewable energy includes renewable source 104 energy Converter 106 energy, electricity, 108 AC, line 110 energy transfer, the controller 114 to the flow of energy and hybrid system 116 energy storage.

[0038] the System 102 renewable energy is arranged in such a way that it was applied electrical energy is the energy of 108 AC to the load 112 from a renewable source 104 energy. Energy coming from renewable source 104 energy is converted into electrical energy 108 AC, and its phase and frequency adjustable Converter 106 energy. Electricity 108 AC is fed to the load 112 on lines 110 energy transfer. Load 112 can be a single user, customer, factory, city or electrical network used for the distribution of electricity to any number of consumers, users, factories or cities. Similarly, the load 112 may be a residential house or a factory (for example, one electrical circuit inside the dwelling or group of dwelling houses or factories.

[0039] If a renewable source 104 energy does not produce energy due to weather conditions or for any other reason, the electricity 118 alternating current is supplied to the load 112 of the hybrid system 116 energy storage. Similarly, when the work line 110 transmission is impaired by reason of weather conditions or for any other reason, electricity 118 AC also will be delivered to the load 112 of the hybrid system 116 energy storage. The hybrid system 116 energy storage can be located near the load 112 or at some distance from it. If the hybrid system 116 energy storage is not what oterom distance from the load 112, the hybrid system 116 can be connected to the power transmission line of 110 for transmission 118 AC to the load 112, or may use other means of transmission. After spending all the energy available in the hybrid system 116 energy storage, the power supply 118 AC to the load 112 is stopped until the energy in a hybrid system 116 will not be replenished. Energy can be directed in a hybrid system 116 energy storage controller 114 to the flow of energy from renewable source 104 energy or from any other source (not shown) under control of the controller 114.

[0040] figure 2 shows a more detailed block diagram of a system 102 renewable energy, which shows that the controller 114 to the flow of energy contains the measuring unit 120 and the block 122 management of energy storage. In the present embodiment, the controller 114 includes measuring unit 120 and the block 122 management energy storage for measurement, calculation, response and control in cases of refusal renewable source 104 energy and/or lines 110 transmission.

[0041] the Measuring unit 120 may be arranged in such a way that it provided a definition of the output power provided by renewable sources is com 104 energy, and/or failure of the transmission lines 110 by measuring one or more physical characteristics of the renewable energy source 104 energy and/or lines 110. These physical characteristics include, without limitation, voltage, current, time, temperature and mechanical stress.

[0042] To ensure accurate measurements of the physical characteristics can be used direct physical contact between the measuring unit 120 and a renewable source 104 energy and/or transmission lines 110. For example, for voltage measurement can be used direct connection of the probe(s) voltmeter with a renewable source 104 and/or transmission lines 110, and for temperature measurement can be used in direct physical contact of thermistor or thermometer with the specified components. Methods of measurement using direct physical contact include (without limitation) analog, digital, and/or other methods of comparison.

[0043] To measure the physical characteristics related to renewable source 104 energy and/or lines 110 energy transfer, can also be used in indirect ways. For example, the measurement of physical characteristics may be impossible using direct measurement as a renewable source 104 is the power and/or line 110 passes may be closed components or be in a remote (or unavailable). Methods of indirect measurement may include, for example, the inductive coupling, a capacitive connection and optical connection.

[0044] the control Unit 122 of the energy storage may be implemented using hardware, software or combinations thereof. The control unit 122 of the energy storage can be a programmable device that can receive information from the measuring unit 120. The control unit 122 energy storage can perform logical processing of input signals, such as signals received from the measuring unit 120, and may generate output signals for use in the system, including the flow of energy in a hybrid system 116 energy storage. The control unit 122 of the energy storage can be used probabilistic and/or adaptive control methods (i.e., self-learning algorithms) for optimum control, selection, switching, synchronization, and any other functions necessary to select and use one of several different batteries, which provide its accumulation and its impact in the form of AC to the load 112.

[0045] figure 3 shows a more detailed block diagram of a system 102 renewable energy in which is illustrated a more detailed diagram of the hybrid system 116 is cumulitive energy. In the illustrative embodiment represented in the figure 3, the hybrid system 116 energy storage contains blocks 124 energy conversion, batteries, 126 and 128 blocks of energy conversion.

[0046] the Blocks 124 energy conversion provides conversion of electric power of the alternating current in the form of energy suitable for the accumulation of appropriate storage medium or a battery. Blocks 124 energy conversion can provide replenishment of energy in the battery 126 after full discharge or at any charge level. The various components can provide systems and methods of energy conversion to accumulate in the battery 126. For example, the electric power of the alternating current can be used to drive an air compressor for producing compressed air which is pumped into the cave or in the tank. In addition, electricity can for example be used in the charger for rechargeable batteries in the charging generator or other electric car, designed for charging an electrochemical cell or battery.

[0047] the Battery 126 hoard or accumulate energy provided by blocks 124 of energy conversion, for the subsequent impact on the accumulated energy in blocks of 128 energy conversion, so that this energy can be submitted from block 128 to the load 112 in the form of AC. For example, the first battery may be electrochemical element, an electrochemical battery or group of such devices, a second battery may be a group of fuel elements, and the third battery can be pumped storage unit. The number and types of media power in the battery 126 may depend on the configuration and location system 102 renewable energy capacity and energy density of this system. The person skilled in the art technique will be clear that the factors considered first when designing the system 102 may vary from one system to another. For example, in one system 102 renewable energy can be used two different carrier of energy in the battery 126, while the batteries 126 another system 102 can be used four different energy carrier. In General, batteries are chosen in such a way that minimizes the total operating cost of the hybrid system energy storage. General operating expenses include the initial acquisition cost of materials, cost of installation and maintenance throughout the life of such a hybrid system energy storage. In one embodiment, the hybrid system energy storage, which can be easily expanded to 10% and cumulonimbi energy provided by a lithium-ion battery, 30% is provided by the sodium-sulphur battery and 60% is provided by lead-acid battery. Li-ion battery is used for the majority of cycles (i.e., accumulation or discharge to stabilize the power provided by source 104 energy for load 112) because of its long life (a large number of cycles of charge-discharge) and high cost for a given capacity. The sodium-sulfur battery is used for a longer and deeper cycles due to the balance of its service life and cost accumulated charge. Lead-acid battery is used for a very long cycles due to its low durability and low cost accumulated charge. Combining the advantages of these different types of batteries used in different proportions, you can reduce the cost of purchase of materials and installation and maintenance costs, and the total period of service may be maximized in terms of restrictions in a particular system.

[0048] the Blocks 128 energy conversion convert the energy stored in the battery 126, into electrical energy 118 AC for transmission to the load 112. In General, the energy stored in the hybrid system 116 energy storage is in a form not suitable for use in electric the network (for example, for transmission lines (110), or if it is electric energy, its phase or frequency may not be suitable for consumer use. To convert the energy contained in a carrier of the battery into electrical energy 118 AC for transmission to the load 112 are various systems and methods. For example, the release of energy from pumped storage reservoir system includes the release of water from a reservoir and ensuring its passage under the action of gravity through a turbine that turns an electric generator to make electricity 118 AC. In one of the embodiments of the invention the system also includes a device for adjusting the phase and frequency of the electric power 118 AC in accordance with the previously used values for submission to the load 112. In another embodiment, as an energy source for the power conversion of energy, generating electricity 118 may be a fuel cell. In another embodiment, the conversion unit energy converts into electricity 118 AC energy generated by the electrochemical element.

[0049] figure 4 shows a more detailed block circuit 122 controls the energy storage, which contains various functional components, such as anal is saying-digital Converter 130, the timer 132, a Central processing unit (CPU) 134, and block 136 exchange of information.

[0050] the Components of the unit 122 controls the energy storage can be implemented using hardware, software or combinations thereof. For optimum control, selection, switching, synchronization, and any other functions necessary to select and use one of several different batteries 126, which provide energy for conversion into electricity 118 AC for transmission to the load 112 can be used probabilistic and/or adaptive management techniques. In addition, the incoming electricity to alternating current is passed in a hybrid system 116 energy storage to replenish and maintain the required or optimal levels of energy in the battery 126. Unit 122 controls the energy storage may perform other functions, without going beyond the scope of the present invention, for example the function of a uniform distribution of energy between the batteries 126.

[0051] the Exchange of information and management components of the system 102 may be implemented using suitable communication means, such as, for example, a telephone network, intranet, extended intranet, Internet terminals, such as terminals, personal digital device is istwa (for example, Palm Pilot®, Blackberry®, cell phone, terminal, etc), communications in real-time, satellite communications, communications delays (not in real time), wireless communication, means of communication with repeaters, LAN, WAN, virtual private network, a network or directly attached devices, keyboard mouse and/or other suitable means of information exchange or data entry. Communication protocols to exchange information between components can provide both serial and parallel data transfer.

[0052] figure 5 illustrates a method 500 of using media, provide energy storage and batteries with different capacity for stabilization of the power provided by a renewable source of energy. At stage 138, the CPU 134 determines the efficiency renewable source 104 energy. If renewable energy inefficient, the CPU 134 on stage 150 selects the battery or hybrid system energy storage to supply energy for conversion into electricity AC on stage 152. On stage 148 electricity AC obtained at the stage 152 is transmitted to the load 112. If at the stage 138 is determined that know the renewable energy source is operable, at stage 140 renewable energy is converted into electricity to AC. On stage 142, the CPU 134 determines whether to replenish the energy in a hybrid system 116 energy storage. If the hybrid system 116 energy storage needs to replenish the energy, the electricity generated alternating current is fed to stage 144 hybrid system 116, and the CPU 134 is transferred to the step 146. If the hybrid system 116 energy storage does not need to replenish the energy that is moving from the stage 142 through 146. On stage 146, the CPU 134 determines the operability line 110 energy transfer. If the line 110 transmission inoperative, the CPU 134 is transferred to the step 150, at which the optimum battery. If at stage 146 is determined that the transmission line 110 energy efficient, the electric power of alternating current is passed at stage 148 to the load 122 of the best battery through the corresponding block of energy conversion.

[0053] it is Necessary to understand that the above method may be a closed loop and be iterative, and it may contain additional stage without going beyond the scope of the invention. To facilitate the implementation of the functions of measurement, control and exchange of information within the system 102 renewable energy in block 114, the control flows the energy use of different functional components, such as analog-to-digital Converter 130, the timer 132, a Central processing unit (CPU) 134, and block 136 exchange of information.

[0054] In the figure 6 presents a block diagram of a system 600 that transfers energy to the load 602. The system 600 includes a source 604 energy, the controller 606 energy flows, the first accumulator 608 and a second battery 610. The first accumulator 608 and a second battery 610 comprise a hybrid system 612 energy storage. Source 604 energy can be a renewable source of energy, such as wind turbine or solar panel, providing a variable output power, or non-renewable source of energy, such as gas turbine, which provides at the output a relatively constant power. In any case, the current requirement of the load 602 in power changes, and the controller 606 energy flows selectively accumulates energy in batteries and ensures the transfer of energy from them in accordance with the current requirement of the load 602 in power.

[0055] a person skilled in the art will understand that the controller 606 energy flows can be directly connected source 604 energy to the load 602 and selectively accumulate and transmit energy for this connection, or the controller 606 may contain device adjusting the phase, frequency and amplitude required for is your source 604 energy to the load 602. In addition, in one embodiment, the controller 606 energy flows manages multiple energy sources to provide current requirement of the load 602 in power. For example, in one embodiment, the load 602 is directly connected to the gas turbine and the wind turbine is connected to the load 602 via the controller 606 energy flows, which selectively accumulates energy from wind turbines and gas turbines, depending on the power transmitted by each energy source, and from the current requirement of the load 602 in power.

Device 706 power control (i.e., power sensor provides a signal indicating to the controller 704 current consumption power of the load 602. In one embodiment, the signal power indicates the difference between the power provided by the source 604 energy, and the current power consumption of the load 602. In another embodiment, the signal power indicates the voltage at the load 602. The device 708 first energy level provides the controller 704 signal of the first energy level, indicating the amount of energy in the first accumulator 608. The device 710 of the second energy level provides the controller 704 signal of the second energy level that indicates the amount of energy in the second battery 610.

In one embodiment, the controller 704 controls the inverter 702 energy by selective transmission of signal accumulation, signal switching, signal category, the first transfer signal and the second signal transmission. Specialist in the art may understand that these signals can be transmitted using a parallel or serial data transmission. Each signal can be transmitted over a dedicated line to the Converter 702 energy, or signals can be transmitted to the Converter 702 energy as the set of States of signals in the package information in the serial data. The Converter 702 energy to signal energy storage provides energy storage provided by source 604 energy, at least one of the battery 608, 610.

[0059] figure 8 shows the diagram of a method of selecting a battery for energy storage provided by source 604 energy, which exceeds the current requirement of the load 602 in power, and the process begins at stage 802. At stage 804, the controller 704 determines whether the power provided by the source 604 energy, the current requirement of the load 602 in power. If the power provided by the source 604 energy does not exceed the current requirement of the load 602 in power, the execution of the method ends at stage 806. If the power provided by the source 604 energy exceeds the current requirement of the load 602 in power, then the controller 704 determines at stage 808 ready is the industry's first battery 608. In one embodiment, the determination of the readiness of the first accumulator 608 includes at least one of the following: determining achieve the amount of energy in the first accumulator 608 maximum threshold level for the first accumulator 608, a determination of the temperature of the first battery 608 specified maximum value, the determination of the excess of the number of cycles of charge-discharge of the first battery 608 specified limit cycles, determining the fall of the efficiency of discharge of the first battery 608 below the specified minimum value, and the definition of excess mechanical stress in the first accumulator 608 limit. If none of these adverse conditions for the first accumulator 608 fails (or the condition is not checked), then the controller determines that the first accumulator 608 is in the ready state, and goes on stage 810 of energy accumulation in the first battery, then return to the step 804. If the first accumulator 608 is in a state of unreadiness, the controller 704 goes on stage 812 to determine the readiness of the second battery 610. In one embodiment, the second battery 610 is the sodium-sulfur electrochemical cell, and his willingness is determined by checking the conditions, Ana is ulichnyh conditions for the first battery 608. If at stage 812 is determined that the second battery is in the ready state, the controller at the stage 814 transmits to the Converter 702 energy team on energy storage in the second battery 610, followed by step 804. If at stage 812 is determined that the second battery 610 is in a state of unreadiness, the controller 704 proceeds to the step 806 (end). Additionally, the controller 704 may send a command to the inverter 702 energy to reduce the flow of energy from source 604 in the load 602 to protect it from excess capacity. Specialist in the art will understand that the controller 704 may be arranged in such a way that he instantly interrupted the execution of the method, the scheme is presented in figure 8, if the current requirement of the load 602 in power exceeds the power provided by the source 604 energy.

[0060] In the figure 9 presents the diagram of a method of selecting a battery for energy storage provided by source 604 energy, which exceeds the current requirement of the load 602 in power, and the process begins at stage 902. At stage 904, the controller 704 determines whether the power provided by the source 604 energy, the current requirement of the load 602 in power. If the power provided by the source 604 e is ergie, does not exceed the current requirement of the load 602 in power, the execution of the method ends at stage 906. If the power provided by the source 604 energy exceeds the current requirement of the load 602 in power, then the controller 704 determines at stage 908, the readiness of the battery 608. If the controller 704 determines at stage 908, the first accumulator 608 is in the ready state, the controller moves to the step 910 of energy accumulation in the first battery, and then proceeds to the step 912. At stage 912, the controller 704 determines whether accumulated already energy in the first battery during a first specified time interval. If the time of accumulation of energy in the first accumulator 608 does not exceed the first specified time interval, the controller 704 is returned to the step 912. Otherwise, i.e. if the energy is accumulated in the first accumulator 608 during the first specified time interval, the controller 704 proceeds to the step 914 to determine the readiness of the second battery. Similarly, if the controller 704 determines at stage 908, the first accumulator 608 is in a state of unpreparedness, it should transition to the step 914. On stage 914, the controller 704 determines the readiness of the second battery 610. If at the stage 914 determines that the secondary battery 610 is shown is anii readiness, the controller 704 on stage 916 transmits to the Converter 702 energy team on energy storage in the second battery 610, followed by step 904. If at the stage 914 determines that the secondary battery 610 is in a state of unreadiness, the controller 704 proceeds to the step 906 (end). Additionally, the controller 704 may send a command to the inverter 702 energy to reduce the flow of energy from source 604 in the load 602 to protect it from excess capacity. Specialist in the art will understand that the controller 704 may be arranged in such a way that he instantly interrupted the execution of the method, the scheme is presented in figure 9, if the current requirement of the load 602 in power exceeds the power provided by the source 604 energy.

[0061] As shown in figure 10, a flowchart of a method for selecting battery for extracting energy from it and then convert and transfer the load 602 begins at stage 1002. At stage 1004, the controller 704 determines whether the power provided by the source 604 energy, the current requirement of the load 602 in power. If the current requirement of the load 602 in power does not exceed the power provided by the source 604 energy, followed by a transition to the step 1006 (end). If the current requirement of the load 602 in power p is Evesham power, provide a source 6042 energy, the controller 704 proceeds to the step 1008 determines the readiness of the first accumulator 608. The willingness of the first accumulator 608 for discharge is determined on the basis of the same conditions that are used for energy storage in the first accumulator 608 except that the controller 704 determines the achievement of the amount of energy in the battery 608 of the first minimum level instead of the first maximum level. If at stage 1008 is determined that the first accumulator 608 is in the ready state, the controller 704 sends the appropriate commands to the inverter 702 energy, doing that the extracts energy from the first battery 608, the transformation of energy in a form suitable for loading 602, and the transfer stage 1010 the converted energy to the load 602. If the first accumulator 608 is in a state of unreadiness, the controller proceeds to the step 1012 to determine the readiness of the second battery 610. If the second battery 610 is in a state of unpreparedness, it should transition to the step 1006 (end). If it is determined that the secondary battery 610 is in the ready state, the controller 704 sends the appropriate commands to the inverter 702 energy, doing that the extracts energy from the second ACC the battery 610, the transformation of energy in a form suitable for loading 602, and the transfer stage 1014 converted energy to the load 602. Then the controller 704 returns to the step 1004. Specialist in the art will understand that the controller 704 may be arranged in such a way that he instantly interrupted the execution of the method, the scheme is presented in figure 10, if the power provided by the source 604 energy, equal and/or exceed the current requirement of the load 602 in power.

[0062] As shown in figure 11, a flowchart of a method for selecting battery for extracting energy from it and then convert and transfer the load 602 begins at stage 1102. At stage 1104, the controller 704 determines whether the power provided by the source 604 energy, the current requirement of the load 602 in power. If the current requirement of the load 602 in power does not exceed the power provided by the source 604 energy, followed by a transition to the step 1106 (end). If the current requirement of the load 602 in power exceeds the power provided by the source 602 of energy, the controller 704 proceeds to the step 1108 determines the readiness of the first accumulator 608. The willingness of the first accumulator 608 for discharge is determined on the basis of the same conditions that are used for energy storage in the first accumulator except the controller 704 determines achieve the amount of energy in the battery 608 of the first minimum level instead of the first maximum level. If at stage 1108 determines that the first battery is in the ready state, the controller 704 determines whether passed energy from the first battery during a second specified time interval. If at stage 1108, the controller 704 determines that the first accumulator 608 is in the ready state, and the energy from the first battery 608 was not transferred to the load 602 within a second specified time interval, the controller 704 sends the appropriate commands to the inverter 702 energy, doing that the extracts energy from the first battery 608, the transformation of energy in a form suitable for loading 602, and the transfer stage 1112 converted energy to the load 602. If at stage 1108, the controller 704 determines that the first accumulator 608 is in a state of unreadiness, or energy from the first battery was transferred to the load 602 within a second specified time interval, the processor 704 is transferred to the step 1114 determine the readiness of the second battery 610. If the second battery 610 is in a state of unpreparedness, it should transition to the step 1106 (end). If it is determined that the second and the battery 610 is in the ready state, the controller 704 sends the appropriate commands to the inverter 702 energy, doing that the extracts energy from the second battery 610, the transformation of energy in a form suitable for loading 602, and the transfer stage 1116 converted energy to the load 602. Then the controller 704 is returned to the step 1104. Specialist in the art will understand that the controller 704 may be arranged in such a way that he instantly interrupted the execution of the method, the scheme is presented in figure 11, if the power provided by the source 604 energy, equal and/or exceed the current power consumption of the load 602.

[0063] As shown in figure 12, a block diagram of a method of energy storage provided by source 604 energy, which exceeds the current power consumption of the load 602 begins at the stage 1202. On stage 1204, the controller 704 determines whether the power provided by the source 604 energy, the current power consumption of the load 602, and if not exceeds, it should transition to the step 1206 (end). If the power provided by the source 604 energy exceeds the current power consumption of the load 602, the controller 704 determines at stage 1208 readiness of the first accumulator 608 to the energy storage. If the first accumulator 608 is in the ready state the spine, the controller 704 sends the appropriate commands to the inverter 702 energy, doing that he provides at stage 1210, so that the speed of energy transfer in the first accumulator 608 does not exceed the threshold speed energy storage, the first battery 608. On stage 1212, the controller 704 determines whether the difference between the power provided by the source 604 energy, and the current requirement of the load 602 in power threshold speed energy storage, the first battery 608. If the difference between the power provided by the source 604 energy, and the current demand for power load 602 does not exceed the threshold speed energy storage first accumulator 608, the controller 704 is returned to the step 1204. If the difference between the power provided by the source 604 energy, and the current demand for power load 602 exceeds a threshold speed energy storage first accumulator 608, the controller 704 on stage 1214 checks the readiness of the second battery 610. If the second battery 610 is in a state of unreadiness, the controller 704 is returned to the step 1204. If the second battery 610 is in the ready state, the controller 704 sends the appropriate commands to the inverter 702 energy, doing that that both the accounts at the stage 1216 accumulation in the second battery 610 energy, provide a source 604 energy that exceeds the amount of the current needs in the power load 602 and the threshold value of the speed of accumulation of the first accumulator 608, the controller 704 is returned to the step 1204. Specialist in the art will understand that the method, which is shown in figure 12, can also be used when the battery discharge 608, 610 to match the output power controller 606 energy flows current requirement of the load 602 in power. In one embodiment, the controller 704 changes the threshold rate of accumulation for the first battery, the threshold rate of accumulation for the second battery, a threshold speed of discharge of the first battery and the threshold speed of discharge of the second battery based on at least one of the following characteristics: cooling capacity and coefficient of heat dissipation of the battery, the expected pattern (profile) changes in ambient temperature, the expected demand load capacity, the expected intensity profile cycles of charge-discharge batteries and profile of energy production by energy source. The controller 704 changes the threshold velocity of the charge and discharge of batteries depending on the above the characteristics, specific to the location of the energy system, to maximize the efficiency of the whole system 600. Specialist in the art will understand that the controller 704 may be arranged in such a way that he instantly interrupted the execution of the method, the scheme is presented in figure 12, if the current requirement of the load 602 in power exceeds the power provided by the source 604 energy.

[0064] As shown in figure 13, diagram of a method of energy storage provided by source 604 energy, which exceeds the current requirement of the load 602 in power, begins at the stage 1302. On stage 1304, the controller 704 determines whether the power provided by the source 604 energy, the current requirement of the load 602 in power, and if not exceeds, it should transition to the stage 1306 (end). If the power provided by the source 604 energy exceeds the current requirement of the load 602 in power, then the controller 704 determines at stage 1308 readiness of the first accumulator 608 to the energy storage. If the first accumulator 608 is in the ready state, the controller 704 determines at stage 1310, than the difference between the power provided by the source 604 energy, and the current requirement of the load 602 in power threshold speed energy storage first accum is the system 608. If not exceeds, the controller 704 sends the appropriate commands to the inverter 702 energy, doing that he provides on stage 1312 energy will be stored in the first accumulator 608, and then returns to the step 1304. If the difference between the power provided by the source 604 energy, and the current requirement of the load 602 in power exceeds a threshold speed energy storage first accumulator 608 (stage 1310), or the battery is in a state of unreadiness (stage 1308), then the controller 704 on stage 1314 checks the readiness of the second battery 610. If the second battery 610 is in a state of unpreparedness, it should transition to the stage 1306 (end). If the second battery 610 is in the ready state, the controller 704 sends the appropriate commands to the inverter 702 energy, doing that he provides on stage 1316 accumulation in the second battery 610 energy provided by source 604 energy, which exceeds the current requirement of the load 602 in power, and the controller 704 is returned to the step 1304. Specialist in the art will understand that the method, which is shown in figure 13, can also be used when the battery discharge 608, 610 to match the output power controller 606 flows of saving and current requirement of the load 602 in power. Specialist in the art will understand that the controller 704 may be arranged in such a way that he instantly interrupted the execution of the method, the scheme is presented in figure 13, if the current requirement of the load 602 in power exceeds the power provided by the source 604 energy.

[0065] As shown in figure 14, the execution of the alignment of energy levels in the first 608 and 610 second battery begins on stage 1402. Then at the stage 1404, the controller 704 determines expired whether a given time interval. If the specified time interval has expired, then at the stage 1406 controller 704 transmits to the Converter 702 energy corresponding commands to the transmission of energy, doing that that provides the energy transfer between the first 608 and 610 second batteries, while the amount of energy in the first battery reaches the first preset level, and then the controller 704 is returned to the step 1402. If the specified time interval has not expired, the controller 704 is transferred to the determination at the stage 1408 achieve the amount of energy in any of the batteries the maximum or minimum levels. If these levels are not reached, then the controller 704 is returned to the step 1402. If you reach one of these levels, the controller 704 sends the appropriate commands to the transfer of energy conversion on the tel 702 energy, doing that that provides the transfer of energy from a battery, the amount of energy which has reached its maximum level, or transmission of energy in the battery, the amount of energy which has reached the minimum level. The controller 704 stops power transmission, when the battery, the amount of energy which has reached its maximum or minimum level reaches a predetermined energy level. In one embodiment, the specified energy levels associated with each battery change depending on the expected profile of the changing needs of the load capacity and the expected profile of change of energy provided by the source. That is, the information collected about the needs of the load power and the output power of the energy source over a certain period is used for the adaptation algorithms, storage and return of energy to maximize the efficiency of the whole system 600, and the associated energy levels (namely, the first and second specified energy levels) are desired state of charge (e.g., percent of capacity) of the respective batteries.

[0066] figure 15 shows an example system 1500 stabilize the power provided by the energy source to the load. The system 1500 is attached through the transformer 1504 bus 1502 between the energy source and the load. In this example, the source of energy is a combination of gas turbine and wind turbine moreover, wind energy is from 15% to 35% of the energy supplied to the load, consuming only about 85 MW to about 210 MW. In this example, the profile needs load capacity is a round-the-clock consumption regardless of the time of year, and the profile of energy production energy source is also a non-energy production, regardless of the time of year. As already mentioned, the profiles of production and consumption of energy are used to define variables within the system (for example, minimum and maximum energy levels for each battery set of energy levels for each battery, and the like). In this system, almost 90% of the cycles are in the range from 2 MW/min up to 4 MW/min Transformer 1504 used in the system is a transformer 480Y/277V-22900A capacity of 2,500 kVA, which is offered on the market a number of suppliers known to specialists. Bus 1502 used in the system, designed for a voltage of 22.9 kW with a frequency of approximately 60 Hz.

[0067] the System 1500 includes the first sodium-sulfur battery 1506, the second sodium-sulfur battery 1508, lithium-ion battery 1510 and lead-acid battery 1512. Capacity lithium-ion battery 1510 is 10% of the entire capacity of the battery system 1500. The capacity of the sodium-sulfur battery is th 1506 and 1508 is 30% of the entire capacity of the battery system 1500. Capacity lead-acid battery is 60% of the entire capacity of the battery system 1500. In this example system that uses only lead-acid batteries would be the life of 3-4 years, while the life expectancy of the above combinations of batteries is 10-15 years.

[0068] Each of the batteries supplied with the appropriate breaker 1514, 1516, 1518 and 1520 DC and matching charger 1522, 1524, 1526 and 1528. When the system 1500 transmits energy into the tire 1502 the first and/or second breakers 1514 and 1516 DC regulate the power transmitted from the first 1506 and/or the second 1508 sodium-sulfur battery in the first inverter 1530. The first inverter 1530 converts the direct current from the output of the first 1514 and/or the second 1516 breaker DC to AC current frequency of 60 Hz. The first filter 1534 removes noise harmonics of the signal of 60 Hz, 480 V and supplies it to the first measuring device 1538. The first measuring device 1538 controls the flow of energy between the system 1500 and bus 1502, collecting data for use in adjusting the algorithms that determine battery that should be used for the accumulation and energy output depending on the state of the system. Similarly, when the system 1500 transmits energy to the Oia on the bus 1502, third 1518 and/or fourth 1520 breakers DC regulate the power transmitted from the lithium-ion battery 1510 and/or lead-acid batteries 1512 second inverter 1532. The second inverter 1532 provides signal 480 At 60 Hz to the second filter 1536 harmonic components, which filters the signal to the second measuring device 1540. The energy transferred from the first 1538 and second 1540 measuring device, passes through the transformer 1504 in the bus 1502.

[0069] When the system 1500 accumulates energy coming from the bus 1502, the first 1538 and/or second 1540 measurement device to receive energy from the transformer 1504 and pass it in first, second, third and/or fourth charger 1522, 1524, 1526 and 1528, respectively. Each charger converts the voltage of 480 V and frequency 60 Hz direct current for transmission to the appropriate battery. Specialist in the art will understand that the battery 1506, 1508, 1510 and 1512 can receive and accumulate the electric energy from the respective chargers, 1522, 1524, 1526 and 1528 with different DC voltages. In addition, the charger can be designed in such a way that they provided a charging all the batteries or individual battery cells, and exp is vnimanie charges of the elements of each of the batteries.

[0070] In another example, the stabilization system power provided by the gas turbine power plant to the load, uses a combination of lithium-ion batteries (10%), sodium-sulfur batteries (30%) and lead-acid batteries (60%). In this example, the profile of consumption is a non-consumption regardless of the time of year. Although gas turbine generators can work with almost constant output power, and this is their optimal mode of operation, however, the current demand of the load power is constantly changing. Thus, the power plant must change the power output of gas turbine generators, and it is necessary to have a backup diesel generators to supply the demands of the power that goes beyond the limits of the gas turbine generators. In this example, the hybrid system energy storage enables the operation of gas turbines with optimal efficiency, and in this case reduces the number of backup diesel generators, or they are not used, resulting in reduced emissions and cost of the power plant.

[0071] In another example uses a transportable system for the stabilization of the power provided by the wind turbine, which includes the flywheel, iti-ion batteries and lead-zinc batteries. In this example, the profile needs loads of power may be unknown due to the transportability of the system, while the power output of the energy source (namely, a wind turbine or turbines) during the day changes. In one embodiment, the system examines the daily profile needs loads of power and adjusts the control parameters to optimize the efficiency of energy use in the system. The system may use any wind turbine number of units proposed, for example, companies Vestas Wind Systems and General Electric Company (for example, V47 capacity of 660 kW Vestas Wind Systems). In this example, the system is calculated in such a manner that a maximum density of accumulated energy and ease of use that is associated with its transportability, which may provide constant power for small or moderate load with renewable energy. This system can replace or expand local installation of electricity, which is provided by the small generators powered by internal combustion engines or diesel engines. The system can also be used in solar cells that provide power to the load.
