[0002] With the increasing global awareness of environmental protection and the proposal of the "dual carbon" goal, wind power and photovoltaic power generation, as important renewable energy sources, play an increasingly critical role in the transformation of energy structure. However, wind power generation and photovoltaic power generation have inherent randomness, intermittency and volatility, resulting in poor power supply stability and difficult to control power quality, which poses a potential threat to the safe and stable operation of the power grid.

[0003] At present, wind farms and photovoltaic power stations usually collect AC power and process it through a booster station. Part of the power is directly sent to the power grid, and the other part is supplied to hydrogen production equipment after voltage reduction and rectification. Specifically:

Figure 1 FIG. 1 is a block diagram of an electric-hydrogen coupling system according to an exemplary embodiment. Figure 1As shown, the system includes an input module 110, an output module 120 and a processing module 130; wherein,

[0048] The input module 110 is used to input electric energy. The input module 110 includes a wind turbine connected via a wind power bus interface, a photovoltaic array connected via a photovoltaic bus interface, and a power grid connected via a grid power interface;

[0050] The processing module 130 is used to obtain the electric energy input by the input module 110 , and output the converted electric energy to the energy storage device and the hydrogen production device through the output module 120 .

[0051] In summary, an electric-hydrogen coupling system provided in an embodiment of the present application is used to input electric energy through an input module 110, and the input module 110 includes a wind turbine connected through a wind power bus interface, a photovoltaic array connected through a photovoltaic bus interface, and a power grid connected through a grid power interface. The output module 120 is used to output electric energy to an energy storage device and a hydrogen production device, and the output module 120 includes a hydrogen production device connected through a hydrogen production power supply interface and an energy storage device connected through a power storage interface. The processing module 130 is used to obtain the electric energy input by the input module 110, and output the converted electric energy to the energy storage device and the hydrogen production device through the output module 120. The problem of low utilization of the electric-hydrogen coupling system in the related art is solved, and the utilization rate of wind and solar power generation is improved.

[0052] Figure 2 is a schematic diagram of the structure of an input module interface according to an exemplary embodiment. Figure 2 As shown, the input module 110 is used to input electric energy, and the input module 110 includes a wind turbine connected via a wind power bus interface, a photovoltaic array connected via a photovoltaic bus interface, and a power grid connected via a grid power interface.

[0053] Optionally, the wind power bus interface is connected to the wind turbine group to receive AC power from the wind turbine group. The electric energy generated by the wind turbine group is usually AC power, which is connected to the power conversion device through the wind power bus interface. The photovoltaic bus interface is connected to the photovoltaic array to receive DC power from the photovoltaic array. The photovoltaic module directly generates DC power, which is connected to the power conversion device through the photovoltaic bus interface. The grid power interface is connected to the power grid to obtain AC power from the power grid when needed, or to send excess power to the power grid when there is excess power generation.

[0054] The input module 110 is connected to different power sources through a variety of interfaces, so that the system can flexibly respond to power needs in different situations, improving the adaptability and stability of the system. By centrally managing and dispatching power from different sources, the input module 110 helps to maximize the use of wind and photovoltaic power generation, reduce the phenomenon of "wind abandonment" and "light abandonment", and ensure the continuity and stability of the hydrogen production process. Even in the case of unstable wind and photovoltaic power generation, stable power can be obtained from the power grid through the grid power interface to ensure the reliable operation of the entire hydrogen coupling system.

[0055] In one embodiment, the output module 120 is used to output electrical energy to the energy storage device and the hydrogen production device. The output module 120 includes the hydrogen production device connected via the hydrogen production power supply interface and the energy storage device connected via the power storage interface.

[0056] Alternatively, if Figure 2 As shown, the hydrogen production power supply interface is connected to the hydrogen production equipment (such as an electrolyzer) to supply the converted DC power to the hydrogen production equipment for water electrolysis to produce hydrogen. It is connected to the energy storage device (such as a battery pack) to store excess power or release power when wind and solar power generation is insufficient to ensure the stable operation of the system.

[0057] The output module 120 distributes electric energy reasonably through the hydrogen production power supply interface and the power storage interface to ensure that both the hydrogen production equipment and the energy storage equipment can obtain the required electric energy. By reducing unnecessary power conversion steps, the appropriate electric energy is directly provided to the hydrogen production equipment and the energy storage equipment, thereby improving the overall energy efficiency of the system. By storing excess electric energy in the energy storage device and releasing it when needed, all renewable energy power generation is effectively utilized, reducing the phenomenon of "abandoning wind" and "abandoning solar power".

[0058] Figure 3 is a schematic diagram of the overall structure of an electric hydrogen coupling system according to an exemplary embodiment. Figure 3 As shown, the processing module 130 is used to obtain the electric energy input by the input module 110, and output the converted electric energy to the energy storage device and the hydrogen production device through the output module 120.

[0059] Optionally, the processing module 130 acts as a hub for power transmission, collects power from wind power, photovoltaic power and the power grid, and distributes it to the hydrogen production equipment and energy storage equipment after internal conversion. By reducing unnecessary power conversion steps and directly providing appropriate power to the hydrogen production equipment and energy storage equipment, the overall energy efficiency of the system is improved.

[0060] In one embodiment, the input module is connected to the processing module, and the processing module is connected to the output module; wherein the processing module includes a DC bus, a transformer, a first AC / DC converter, a second AC / DC converter, a first DC / DC converter, and a second DC / DC converter. It should be noted that: Figure 3Among them, AC / DC converter 1 is a first AC / DC converter, AC / DC converter 2 is a second AC / DC converter, DC / DC converter 1 is a first DC / DC converter, and DC / DC converter 2 is a second DC / DC converter.

[0061] When the input module is connected to the processing module,

[0062] The wind power bus interface is connected to the DC busbar through the first AC / DC converter;

[0063] The photovoltaic bus interface is connected to the DC busbar.

[0064] The grid power interface is connected to the transformer, and the transformer is connected to the DC busbar through the second AC / DC converter.

[0065] When the processing module is connected to the output module,

[0066] The DC busbar is connected to the power storage interface through a first DC / DC converter;

[0067] The DC busbar is connected to the hydrogen production power supply interface through a second DC / DC converter.

[0068] Optionally, an AC / DC converter, also known as a rectifier, is a device that converts alternating current (AC) into direct current (DC). In this embodiment, the AC / DC converter converts the AC power provided by the wind turbine or the power grid into DC power for subsequent processing. A DC / DC converter is a device that converts one DC voltage into another DC voltage, which can both step up and step down. In this embodiment, the DC / DC converter regulates the DC voltage flowing to or from the energy storage device, as well as the DC voltage supplied to the hydrogen production equipment. As the hub of power transmission, the DC busbar collects electrical energy from the input module 110 and distributes it to the output module 120 after internal conversion. The transformer is used to adjust the voltage level to ensure electrical isolation and voltage matching between the power grid and the system.

[0069] Connection between the input module 110 and the processing module 130: The wind power bus interface is connected to the DC busbar through the first AC / DC converter. The AC power generated by the wind turbine is converted into DC power and connected to the DC busbar. The photovoltaic bus interface is directly connected to the DC busbar. The DC power generated by the photovoltaic array is directly connected to the DC busbar. The grid power interface is connected to the transformer, and the transformer is connected to the DC busbar through the second AC / DC converter. The AC power provided by the power grid is adjusted to a voltage level through a transformer, and then converted into DC power through a second AC / DC converter and connected to the DC busbar.

[0070] Connection between the processing module 130 and the output module 120: The DC busbar is connected to the power storage interface through the first DC / DC converter, and is connected to the hydrogen production power supply interface through the second DC / DC converter. The power storage interface adjusts the DC voltage flowing to or from the energy storage device through the first DC / DC converter to achieve the storage and release of electric energy. The hydrogen production power supply interface adjusts the DC voltage supplied to the hydrogen production device through the second DC / DC converter to ensure that the hydrogen production device can operate stably.

[0071] The electric energy generated by the wind turbine is supplied to the hydrogen production equipment after the second conversion of the first AC / DC converter and the second DC / DC converter, and the electric energy generated by the photovoltaic array is supplied to the hydrogen production equipment after the first conversion of the second DC / DC converter. The power conversion process in the electric-hydrogen coupling system is reduced, the power loss is reduced, and the energy efficiency of the system is improved. The problem of low utilization rate of the electric-hydrogen coupling system in related technologies is solved, and the utilization rate of wind and solar power generation is improved.

[0072] In one embodiment, when the processing module obtains the electric energy input by the input module and converts the electric energy and outputs it to the energy storage device through the output module, it is used to:

[0073] When the electric energy input by the input module is greater than or equal to the first preset electric energy, the processing module outputs the electric energy to the battery pack for storage through the first DC / DC converter and the power storage interface of the output module, and outputs it to the electrolyzer through the second DC / DC converter and the hydrogen production power supply interface in the output module to provide electricity for hydrogen production; the remaining electric energy after storage in the battery pack and hydrogen production is transmitted to the power grid through the second AC / DC converter and the transformer.

[0074] Optionally, when the input electric energy is greater than or equal to the first preset electric energy, electricity is stored first. When the input electric energy is sufficient, the excess electric energy is first used to charge the battery pack in case of emergency. The remaining electric energy after storage is used for hydrogen production to ensure that the electrolyzer obtains sufficient electric energy for hydrogen production and increase hydrogen production. The remaining electric energy after hydrogen production is transmitted to the power grid to avoid energy waste and increase economic benefits. Make full use of wind power and photovoltaic power generation to reduce the phenomenon of "abandoning wind" and "abandoning light". By using electric energy in multiple ways, the overall utilization rate of energy is improved.

[0075] When the electric energy input by the input module is less than the first preset electric energy, the processing module outputs the electric energy to the electrolyzer through the second DC / DC converter and the hydrogen production power supply interface in the output module to provide electricity for hydrogen production, and the battery pack in the output module provides electricity for hydrogen production.

[0076] Optionally, when the input power is less than the first preset power, priority is given to ensuring the power supply for hydrogen production. Even if the input power is insufficient, priority is given to ensuring the power supply of the electrolyzer to maintain the continuity of the hydrogen production process. The stored power in the battery pack is used to supplement the power required for hydrogen production to ensure that the hydrogen production process is not affected.

[0077] When the electric energy input by the input module is less than the second preset electric energy, the electricity in the power grid is output to the electrolyzer through the transformer, the second AC / DC converter, the second DC / DC converter and the hydrogen production power supply interface in the output module to provide electricity for hydrogen production.

[0078] When the input power is less than the second preset power, the grid is replenished to obtain power from the grid to ensure that the electrolyzer can continue to work. Through transformers and converters, electrical isolation and voltage matching between the grid and the system are achieved to ensure the safety and compatibility of the system. Even in extreme cases, power can be obtained from the grid to ensure the normal operation of the entire system. Grid replenishment enhances the flexibility of the system, enabling it to operate stably under various conditions.

[0079] The electric-hydrogen coupling system gives priority to hydrogen production and grid connection of surplus electricity, reducing the grid’s power receiving capacity requirements, alleviating the problems of “wind abandonment” and “solar abandonment” and improving the utilization rate of wind and solar power generation.

[0080] In one embodiment, the transformer is an isolation transformer for isolating the electrical connection between the DC busbar and the grid.

[0081] Optionally, the isolation transformer transfers energy through magnetic coupling, without directly connecting the power grid and the system, thus achieving electrical isolation. The isolation transformer can effectively prevent the impact of faults or interference in the power grid on the internal equipment of the system, improving the overall safety of the system. Electrical isolation reduces the impact of electromagnetic interference in the power grid on the internal circuits of the system, improving the anti-interference ability of the system.

[0082] In summary, an electric-hydrogen coupling system provided in an embodiment of the present application is used to input electric energy through an input module 110, and the input module 110 includes a wind turbine connected through a wind power bus interface, a photovoltaic array connected through a photovoltaic bus interface, and a power grid connected through a grid power interface.

[0086] Step S103: According to the power state of the renewable energy, the DC bus outputs the power to the hydrogen production equipment and the energy storage equipment through at least one DC / DC converter.

[0087] In summary, the present application provides a method for coupling electricity and hydrogen. By constructing multiple different independent billing accounts.
