Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0027] This invention provides a renewable energy hydrogen production, storage, and power generation system, such as... Figure 1 As shown, the renewable energy hydrogen production and storage power generation system 1 is connected to the electrical equipment 2 and includes: a renewable energy power generation system 11, a configuration system 12, a hydrogen production system 13, a hydrogen fuel cell power generation system 14, a hydrogen storage system 15, a comparison system 16, and a transmission system 17.

[0028] The configuration system 12 is connected to the renewable energy power generation system 11, the hydrogen production system 13, the hydrogen fuel cell power generation system 14, and the hydrogen storage system 15, respectively; the hydrogen production system 13 and the hydrogen fuel cell power generation system 14 are connected.

[0029] The comparison system 16 is connected to the renewable energy power generation system 11, the hydrogen fuel cell power generation system 14 and the transmission system 17 respectively; the transmission system 17 is connected to the renewable energy power generation system 11 and the hydrogen fuel cell power generation system 14 respectively.

[0030] It should be understood that the system may also include other devices and equipment.

[0031] Specifically, the renewable energy power generation system 11 includes a photovoltaic power generation system 111 and a wind power generation system 112.

[0032] Furthermore, the function of each device in the above system will be explained.

[0033] The renewable energy power generation system 11 acquires a renewable energy dataset, determines the renewable energy power generation based on the dataset, and sends the renewable energy power generation to the configuration system 12.

[0034] The renewable energy dataset includes photovoltaic energy datasets and wind energy datasets; renewable energy power generation includes photovoltaic power generation and wind power generation.

[0035] Specifically, in the renewable energy power generation system 11, the photovoltaic power generation system 111 acquires a photovoltaic energy dataset and inputs the photovoltaic energy dataset into the photovoltaic power generation simulation model to obtain the corresponding photovoltaic power generation; the wind power generation system 112 acquires a wind power energy dataset and inputs the wind power energy dataset into the wind power generation simulation model to obtain the corresponding wind power generation.

[0036] The photovoltaic power generation simulation model is shown in the following equation (1):

[0037]

[0038] In the formula: I represents the output current of the photovoltaic power generation system; V represents the output voltage of the photovoltaic power generation system; I s I represents the short-circuit current at a given ambient temperature. m V represents the maximum operating current under a certain light intensity. c V represents the open-circuit voltage at a given ambient temperature. m This indicates the maximum operating voltage under a certain light intensity.

[0039] According to the above relationship (1), the I-V curve of the photovoltaic power generation system 111 can be obtained. Furthermore, the corresponding photovoltaic power generation can be determined based on the I and V.

[0040] The simulation model for wind power generation is shown in the following equation (2):

[0041]

[0042] In the formula: P represents the power of the wind turbine; ρ represents the density of the wind turbine rotor material; r represents the radius of the wind turbine rotor; v represents the wind speed; λ represents the tip speed ratio of the wind turbine blades; C1, C2, C3, C4, C5 and C6 all represent relevant parameters of the wind turbine, which can generally be taken as 0.52, 116, 0.4, 5, -21 and 0.007 respectively; β represents the blade intercept angle of the wind turbine rotor.

[0043] According to the above relationship (2), the power generation P of the wind power generation system 112 can be obtained. Furthermore, the corresponding wind power generation can be determined based on the power generation P.

[0044] Furthermore, simulation models were performed for both photovoltaic power generation systems and wind power generation systems. Therefore, this invention is applicable not only to standalone photovoltaic hydrogen production and storage power generation systems or wind power hydrogen production and storage power generation systems, but also to photovoltaic and wind power combined hydrogen production and storage power generation systems.

[0045] After receiving the renewable energy generation from the renewable energy power generation system 11, the configuration system 12 configures a hydrogen production system 13 that matches the renewable energy generation using a preset first simulation model, and then sends the renewable energy generation to the hydrogen production system 13.

[0046] Under the influence of the received renewable energy power generation, the hydrogen production system 13 uses a preset second simulation model to perform hydrogen production operations, obtain the amount of hydrogen produced, namely the first amount of hydrogen, and send the first amount of hydrogen to the hydrogen fuel cell power generation system 14.

[0047] Specifically, the electrolytic cell is equivalent to a varistor nonlinear load, and the voltage V of the electrolytic cell can be expressed by the following relationship (3):

[0048]

[0049] In the formula: V0 represents the voltage of the electrolytic cell; V R R represents the reversible voltage; m represents the ohmic resistance of the electrolyte; I1 represents the area of ​​a single electrode; K and s represent the relevant parameters of electrode overvoltage; and T represents the temperature of the electrolyte.

[0050] The hydrogen production system 13 decomposes under the action of V obtained from the above relationship (3) and produces hydrogen.

[0051] The hydrogen fuel cell power generation system 14 receives the power demand sent by the electrical device 2, and determines the second hydrogen quantity of the hydrogen fuel cell power generation system based on the power demand, and sends the second hydrogen quantity to the configuration system 12.

[0052] Specifically, the electricity demand sent by the electrical device 2 is the amount of electricity that the hydrogen fuel cell power generation system needs to provide to the user device. Furthermore, the hydrogen fuel cell power generation system 14 uses hydrogen to generate electricity. Therefore, upon receiving the electricity demand, the amount of hydrogen required by the hydrogen fuel cell power generation system 14, i.e., the second amount of hydrogen, can be determined using a preset third simulation model.

[0053] In one embodiment, a proton exchange membrane fuel cell system is used as the hydrogen fuel cell power generation system 14, and the preset third simulation model is described.

[0054] Specifically, proton exchange membrane fuel cells (PEMFCs) have the characteristics of low operating temperature and fast start-stop response, and can convert hydrogen into electrical energy for users. The output voltage of a fuel cell can be expressed as the Nernst voltage of the fuel cell minus activation loss, ohmic loss, and concentration loss, as shown in the following equation (4):

[0055]

[0056] In the formula: V1 represents the output voltage of the fuel cell; T1 represents the temperature of the fuel cell; P H P represents the partial pressure of hydrogen gas inside the fuel cell. o The value represents the partial pressure of oxygen inside the fuel cell; i represents the current in the fuel cell; i m Indicates the limiting current; C o R1 represents the oxygen concentration inside the fuel cell; R2 represents the internal resistance of the fuel cell.

[0057] Finally, the configuration system 12 can obtain the hydrogen storage amount based on the received first hydrogen amount and second hydrogen amount, and based on the hydrogen storage amount, it configures the hydrogen storage system 15 using a preset fourth simulation model, and sends the hydrogen storage amount to the configured hydrogen storage system 15 for storage.

[0058] Specifically, the first hydrogen quantity represents the actual amount of hydrogen produced by the hydrogen production system 13 received by the hydrogen fuel cell power generation system 14, and the second hydrogen quantity represents the actual amount of hydrogen required by the hydrogen fuel cell power generation system 14. Therefore, the hydrogen storage quantity can be obtained based on the first and second hydrogen quantities.

[0059] Furthermore, the configuration system 12 can configure a hydrogen storage system 15 that matches the hydrogen storage capacity through a preset fourth simulation model.

[0060] Specifically, the hydrogen storage system 15 uses a hydrogen compressor to store hydrogen. The power consumed by the hydrogen compressor to compress the hydrogen is provided by the electricity generated by the renewable energy power generation system 11, as shown in equation (5):

[0061]

[0062] In the formula: P0 represents the power consumed by the hydrogen compressor to compress hydrogen; C represents the specific heat capacity of hydrogen; T2 represents the inlet temperature; W represents the outlet velocity; P1 represents the inlet pressure; P2 represents the outlet pressure; k represents the specific heat ratio of hydrogen under standard conditions (approximately equal to 1.4); η represents the efficiency of the hydrogen compressor.

[0063] The power P0 consumed by the hydrogen compressor to compress hydrogen can be obtained through the above relationship (4). Furthermore, a corresponding hydrogen storage system 15 is configured according to this power P0.

[0064] Through the above embodiments of the present invention, the configurations of the various subsystems in the renewable energy hydrogen production and storage power generation system are coordinated, ensuring the safety and stability of the renewable energy hydrogen production and storage power generation system during operation.

[0065] Furthermore, the renewable energy power generation system 11 uses renewable energy to generate electricity to power the electrical equipment 2; the hydrogen fuel cell power generation system 14 uses hydrogen to power the electrical equipment 2.

[0066] Specifically, the comparison system 16 receives the renewable energy power generation from the renewable energy power generation system 11 and the electricity demand from the hydrogen fuel cell power generation system 14, compares the renewable energy power generation and the electricity demand, and sends the comparison result to the transmission system 17.

[0067] When the renewable energy generation exceeds the electricity demand, that is, when the renewable energy power generation system 11 can meet the electricity demand of the electrical equipment 2, the transmission system 17 sends a power generation control command to the renewable energy power generation system 11, so that the renewable energy power generation system 11, under the control of the power generation control command, uses renewable energy generation to supply electricity to the electrical equipment 2.

[0068] When the amount of renewable energy generated is less than the amount of electricity demanded, that is, when the renewable energy power generation system 11 cannot meet the electricity demand of the electrical equipment 2, the hydrogen fuel cell power generation system 14 is needed to continue to supply power to the electrical equipment 2.

[0069] Specifically, the transmission system 17 sends a power generation control command to the hydrogen storage system 15, so that the hydrogen storage system 15, under the control of the power generation control command, selects the amount of hydrogen required by the hydrogen fuel cell power generation system 14 from the stored hydrogen (hydrogen storage amount), that is, the second amount of hydrogen, and sends the second amount of hydrogen to the hydrogen fuel cell power generation system 14.

[0070] After receiving the second amount of hydrogen, the hydrogen fuel cell power generation system 14 converts the second amount of hydrogen into the corresponding amount of hydrogen fuel cell power generation, and uses the hydrogen fuel cell power generation to supply power to the electrical equipment 2.

[0071] Therefore, by implementing this invention, a stable power supply to electrical equipment is achieved, while ensuring power supply safety and economy.

[0072] The renewable energy hydrogen production and storage power generation system provided in this invention configures the hydrogen production system based on the renewable energy power generation, and simultaneously utilizes the hydrogen production system to obtain a first amount of hydrogen. The second amount of hydrogen required by the hydrogen fuel cell power generation system is determined based on the electricity demand of the electrical equipment. Furthermore, by comparing the second amount of hydrogen with the first amount of hydrogen, the required hydrogen storage capacity of the hydrogen storage system can be obtained, and the hydrogen storage system is configured according to this capacity. This ensures that the configuration of each subsystem in the renewable energy hydrogen production and storage power generation system is coordinated, guaranteeing the safety and stability of the renewable energy hydrogen production and storage power generation system during operation.

[0073] This invention also provides a renewable energy hydrogen production and storage power generation method, used in a renewable energy hydrogen production and storage power generation system 1 as described in this invention embodiment, wherein the renewable energy hydrogen production and storage power generation system 1 is connected to an electrical device 2; as Figure 2As shown, the method includes the following steps:

[0074] Step 201: Obtain the renewable energy dataset and the electricity demand of the electrical equipment.

[0075] The renewable energy dataset includes a photovoltaic energy dataset and a wind power energy dataset.

[0076] Specifically, at the renewable energy power generation system 11, a photovoltaic energy dataset is obtained through the photovoltaic power generation system 111, and a wind energy dataset is obtained through the wind power generation system 112.

[0077] The hydrogen fuel cell power generation system 14 receives the power demand sent by the electrical equipment 2.

[0078] Step 202: Determine the renewable energy generation based on the renewable energy dataset.

[0079] Renewable energy power generation includes photovoltaic power generation and wind power generation.

[0080] Specifically, the photovoltaic power generation system 111 determines the photovoltaic power generation based on the photovoltaic energy dataset; the wind power generation system 112 determines the renewable energy power generation based on the wind power energy dataset.

[0081] The specific determination process is described in the functional description of the photovoltaic power generation system 111 and the wind power generation system 112 in the embodiments of the present invention, and will not be repeated here.

[0082] Step 203: Based on the renewable energy power generation and the electricity demand, determine the first hydrogen quantity and the second hydrogen quantity through a preset second simulation model and a preset third simulation model.

[0083] The renewable energy power generation system 11 provides electricity to the hydrogen production system 13, namely, renewable energy power generation. Furthermore, under the action of this renewable energy power generation, the hydrogen production system 13 decomposes to produce the corresponding hydrogen.

[0084] Specifically, after the renewable energy power generation system 11 sends the renewable energy power generation to the hydrogen production system 13, the amount of hydrogen produced by the hydrogen production system 13 through the preset second simulation model can be determined, namely the first amount of hydrogen.

[0085] For the specific implementation process, please refer to the description of the interaction process and function of the renewable energy power generation system 11 and hydrogen production system 13 in the embodiments of the present invention, which will not be repeated here.

[0086] Furthermore, the hydrogen fuel cell power generation system 14 uses hydrogen to power the electrical equipment. Therefore, once the power demand of the electrical equipment 2 is determined, the amount of hydrogen required by the hydrogen fuel cell power generation system 14, i.e., the second amount of hydrogen, can be calculated using a preset third simulation model. The specific calculation process is detailed in the functional description of the hydrogen fuel cell power generation system 14 in this embodiment of the invention, and will not be repeated here.

[0087] Step 204: Compare the renewable energy generation with the electricity demand.

[0088] Specifically, the renewable energy power generation system 11 supplies power to the electrical equipment 2 by sending renewable energy power to the electrical equipment 2.

[0089] Therefore, in order to meet the power supply needs of electrical equipment, it is necessary to compare the renewable energy power generation provided by the renewable energy power generation system 11 with the power demand of the electrical equipment 2.

[0090] Step 205: When the renewable energy generation exceeds the electricity demand, the renewable energy generation is used to generate electricity for the electrical equipment.

[0091] Specifically, when the renewable energy power generation exceeds the electricity demand, it indicates that the renewable energy power generation system 11 can meet the power supply demand of the electrical equipment 2. In this case, the renewable energy power generation provided by the renewable energy power generation system 11 can be used directly to generate electricity for the electrical equipment 2.

[0092] Step 206: When the renewable energy power generation is less than the electricity demand, determine the hydrogen fuel cell power generation based on the second hydrogen quantity, generate electricity for the electrical equipment based on the hydrogen fuel cell power generation, and determine the hydrogen storage quantity based on the first hydrogen quantity and the second hydrogen quantity.

[0093] Specifically, when the renewable energy power generation is less than the electricity demand, it indicates that the renewable energy power generation system 11 cannot meet the power supply demand of the electrical equipment 2. At this time, it is necessary to combine the hydrogen fuel cell power generation system 14 to supply power to the electrical equipment 2. That is, the hydrogen fuel cell power generation system 14 uses the second amount of hydrogen to generate electricity, obtains the hydrogen fuel cell power generation, and sends the hydrogen fuel cell power generation to the electrical equipment 2 to realize the power supply to the electrical equipment 2.

[0094] Furthermore, the amount of hydrogen produced by the hydrogen production system 13 can be compared with the amount of hydrogen used by the hydrogen fuel cell power generation system 14 to obtain the amount of hydrogen that the hydrogen storage system 15 needs to store, i.e. the hydrogen storage capacity, so that the hydrogen fuel cell power generation system 14 can directly use the hydrogen stored in the hydrogen storage system 15 to generate electricity.

[0095] Specifically, when the first amount of hydrogen produced by the hydrogen production system 13 is greater than the second amount of hydrogen required by the hydrogen fuel cell power generation system 14, the hydrogen storage amount = the first amount of hydrogen - the second amount of hydrogen.

[0096] When the amount of hydrogen produced by the hydrogen production system 13 is equal to the amount of hydrogen required by the hydrogen fuel cell power generation system 14, no storage is required.

[0097] Furthermore, when the first amount of hydrogen produced by the hydrogen production system 13 is less than the second amount of hydrogen required by the hydrogen fuel cell power generation system 14, hydrogen production continues to be carried out by the hydrogen production system 13 so that the amount of hydrogen meets the second amount of hydrogen required by the hydrogen fuel cell power generation system 14.

[0098] The renewable energy hydrogen production and storage power generation method provided in this invention utilizes the safe and stable renewable energy hydrogen production and storage power generation system provided in this invention to produce hydrogen and store energy, thereby improving energy consumption efficiency and further reducing carbon emissions from the energy consumption end, resulting in good economic and social benefits.
