[0062] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0063] With the widespread application of hydrogen, the demand for hydrogen production is increasing. In order to reduce environmental pollution and energy consumption, new energy power generation and hydrogen production technology has been recognized. It uses renewable new energy to generate electricity and then uses the principle of water electrolysis to produce hydrogen. At present, photovoltaic power generation is the most common.

[0064] In the process of using photovoltaic power generation to produce hydrogen, it is easy to cause Shanghai 2024-11478 (M240483CNI) due to the fluctuation of photovoltaic power generation.

[0065] Leading to a decrease in hydrogen production efficiency and energy utilization

[0066] Based on this, the present application embodiment provides a control method for a hydrogen production system, referring to Figure 1 The flow chart of the control method of the hydrogen production system shown is as follows. The method includes the following processing procedures.

[0067] S100: Acquire a plurality of predicted power generation parameters for photovoltaic power generation in a target time period.

[0068] The hydrogen production system consists of two parts, one is photovoltaic power generation, and the other is water electrolysis hydrogen production. Among them, photovoltaic power generation uses photovoltaic modules to generate electricity and transmits the generated electricity to the water electrolysis hydrogen production part for use in the water electrolysis process; water electrolysis hydrogen production includes multiple electrolytic cells, which use electrolytic cells to achieve hydrogen production.

[0069] In the process of photovoltaic power generation, the electricity generated by photovoltaic modules will be affected by sunlight. Different sunlight intensities will generate different electricity. Therefore, during the operation of photovoltaic modules, the power generation parameters will fluctuate. Through the prediction model or prediction algorithm, multiple time nodes within the target time period are predicted to obtain multiple predicted power generation parameters.

[0070] Among them, each predicted power generation parameter corresponds to a different time node within the target time period.

[0071] Specifically, the method for obtaining the predicted power generation parameters is not specifically limited in this embodiment. For example, in one application scenario, the predicted power generation parameters can be obtained by combining the historical operation data of photovoltaic power generation with the predicted weather data.

[0072] S102: Determine fluctuations of power generation parameters of photovoltaic power generation according to a plurality of predicted power generation parameters.

[0073] After obtaining a plurality of predicted power generation parameters, since each predicted power generation parameter corresponds to a predicted time node, the fluctuation of the power generation parameter corresponding to the time can be obtained.

[0074] Among them, the fluctuation of power generation parameters characterizes the fluctuation of multiple predicted power generation parameters. Specifically, the fluctuation includes at what time node, in what direction and to what value. If a two-dimensional coordinate system is established with time as the horizontal axis and the amplitude of the predicted power generation parameter as the vertical axis, the fluctuation of power generation parameters can be represented as a curve. When the curve extends upward, it represents the fluctuation of the predicted power generation parameter in the direction of increase, and when the curve extends downward, it represents the fluctuation of the predicted power generation parameter in the direction of decrease.

[0075] S104, regulating the operating states of the plurality of electrolytic cells and / or the operating parameters of the electrolytic cells in operation according to fluctuations in the power generation parameters.

[0076] Shanghai 2024-11478 (M240483CNI)

[0077] In one embodiment, only the operating status of multiple electrolyzers can be regulated. The operating status includes running and shutting down. When the electrolyzer is running, it indicates that the electrolyzer is producing hydrogen, and when the electrolyzer is shut down, it indicates that the electrolyzer is not producing hydrogen. According to the fluctuation of power generation parameters, at least the fluctuation range of power generation parameters of photovoltaic power generation within the target time period can be known. Therefore, according to the fluctuation range, it can be determined how many electrolyzers to control the operation, and even which specific electrolyzers to control the operation can be determined, so that the power consumption and power demand of all running electrolyzers are close to the predicted power generation parameters.

[0078] In one embodiment, only the operating parameters of the running electrolyzer can be regulated, wherein the operating parameters include the electrolysis power and water supply temperature of the electrolyzer, and specifically, the operating parameters refer to parameters related to the power generation parameters of photovoltaic power generation or the hydrogen production efficiency, which are not specifically limited in this embodiment.

[0079] By adopting this embodiment, the operating state and operating parameters of the electrolyzer are regulated according to the fluctuation of power generation parameters, so that the operation of the entire hydrogen production system is adaptively adjusted with the fluctuation of photovoltaic power generation, ensuring full utilization of electricity and maximization of hydrogen production efficiency, improving the rationality of electricity use, and thus helping to improve hydrogen production efficiency and energy utilization efficiency.

[0080] In a possible embodiment of the present application, the fluctuation of power generation parameters includes the amplitude of the power parameters, the change trend of the power parameters and the time point of change of the change trend.

[0081] The electrical parameter amplitude refers to the magnitude of the electrical parameter, for example, when the electrical parameter is voltage, it refers to the magnitude of the voltage, and when the electrical parameter is current, it refers to the magnitude of the current. The change trend of the electrical parameter includes increase and decrease.

[0082] According to the fluctuation of power generation parameters, the operating states of multiple electrolytic cells and / or the operating parameters of the electrolytic cells in operation are regulated, including:

[0083] According to the amplitude range of the electrical parameter amplitude and the operating conditions of each electrolytic cell, the corresponding electrolytic cell is controlled to operate in the target time period.

[0084] And / or, a parameter control curve is generated for the running electrolytic cell according to the electrical parameter change trend and the change trend change time point, so as to control the operating parameters of the running electrolytic cell according to the parameter control curve during the target time period.

[0085] In one embodiment, when it is necessary to adjust the operating state of multiple electrolytic cells, according to the electrical parameter amplitude Shanghai 2024-11478 (M240483CNI)

[0086] That is, at least one electrolyzer is selected for operation according to the models or structural configurations of multiple electrolyzers (different models or structural configurations make the electrolyzers have different electrical parameter requirements such as voltage and current when producing hydrogen), so that the power consumption and power demand of the operating electrolyzer do not exceed the amplitude range of the electrical parameter amplitude and are close to the maximum amplitude of the electrical parameter amplitude.

[0087] In one embodiment, when it is necessary to regulate the operating parameters of the running electrolytic cell, a parameter regulation curve is first generated, and then the corresponding operating parameters are controlled according to the parameter regulation curve. For ease of understanding, for example, the parameter regulation curve includes a regulation curve for the electrolysis power of the electrolytic cell. Since the electrolysis power will change with the change of the current transmitted by photovoltaic power generation, after obtaining the trend of the change of the electrical parameters, the regulation curve of the electrolysis power can be generated according to the trend of the change of the electrical parameters, mainly based on the correlation between the electrolysis power and the current transmitted by photovoltaic power generation. Thus, a parameter regulation curve related to time can be obtained. When the actual time reaches the corresponding time node within the target time period, the operating parameters of the electrolytic cell can be regulated to the ordinate value of the parameter regulation curve.

[0088] By adopting this implementation method, the operation of the corresponding electrolyzer can be controlled according to the amplitude range of the electrical parameter amplitude, that is, the number of electrolyzers and the electrolyzers that need to be operated can be regulated, so that the operating electrolyzers can adapt to the fluctuation of the power generation parameters of photovoltaic power generation, so that the operating electrolyzers can maximize the use of photovoltaic power generation electricity and improve the efficiency of electric energy utilization. At the same time, it is also possible to generate parameter control curves for each electrolyzer according to the change trend of the electrical parameters and the time point of the change trend, so that the operating parameters of the electrolyzer are continuously regulated in the target time period according to the parameter control curve, ensuring the continuity and foresight of the regulation of the operating parameters.

[0089] Optionally, in an implementation of this embodiment, the electrical parameter amplitude includes a voltage amplitude and a power amplitude, and the operating conditions include a voltage range and a power consumption range of the electrolytic cell.

[0090] Among them, voltage amplitude refers to voltage value, and electric quantity amplitude refers to electric energy value.

[0091] According to the amplitude range of the electrical parameter amplitude and the operating conditions of each electrolytic cell, the corresponding electrolytic cell is controlled to operate in the target time period, including:

[0092] Determine the electrolytic cell whose voltage range is within the amplitude range of the voltage amplitude as the electrolytic cell to be operated;

[0093] Control the total power consumption range of the electrolytic cell to be operated so that it does not exceed the power amplitude range of the power Shanghai 2024-11478 (M240483CNI)

[0094] Unlock the slot and run.

[0095] In one embodiment, first, electrolytic cells that meet the voltage amplitude range are screened according to the voltage range to obtain at least one electrolytic cell to be operated. Then, the electrolytic cell to be operated whose total power consumption range does not exceed the power amplitude range and is closest to the upper limit of the power amplitude range is calculated from all the electrolytic cells to be operated, and the electrolytic cell to be operated is operated.

[0096] By adopting this implementation method, when controlling the running electrolyzer, both voltage and power consumption are considered, so that the running electrolyzer can fully adapt to the fluctuation of photovoltaic power generation within the target time period, and improve the efficiency of electricity use and hydrogen production.

[0097] Optionally, in an implementation of this embodiment, as Figure 2 As shown, a parameter control curve is generated for the electrolytic cell in operation according to the change trend of the electrical parameters and the time point of the change trend, including:

[0098] S200, determining the parameter control direction of the electrolytic cell in operation according to the change trend of the electrical parameters.

[0099] Among them, different types of parameters of the electrolytic cell correspond to different parameter control directions, that is, the parameter control direction is determined according to the correlation between the parameters of the corresponding type of electrolytic cell and the electrical parameters of photovoltaic power generation. Specifically, when the trend of the electrical parameter change is increasing, the parameter control direction of the electrolytic cell is also increasing, and when the trend of the electrical parameter change is decreasing, the parameter control direction of the electrolytic cell is also decreasing; when the trend of the electrical parameter change is increasing, the parameter control direction of the electrolytic cell is decreasing, and when the trend of the electrical parameter change is decreasing, the parameter control direction of the electrolytic cell is increasing.

[0100] S202, determining a time point for changing the control direction of the electrolytic cell in operation according to the time point for changing the change trend.

[0101] In one embodiment, the time point at which the variation trend changes is the time point at which the control direction of the electrolytic cell changes.

[0102] S204: Generate a parameter control curve according to the parameter control direction and the control direction change time point.

[0103] At the time point when the control direction changes, a curve is drawn according to the parameter control direction of the next stage to generate a parameter control curve.

[0104] Among them, the parameter control curve includes at least one of the water supply temperature control curve, water supply pressure control curve, water supply flow control curve, electrolysis current control curve and electrolysis power control curve of the electrolytic cell, and the operating parameters include at least one of Shanghai 2024-11478 (M240483CNI) among the water supply temperature, water supply pressure, water supply flow, electrolysis current and electrolysis power.

[0105] By adopting this embodiment, parameter control curves can be generated for multiple operating parameters, so that multiple operating parameters can be regulated at the same time, which is beneficial to improving the effect of regulation, so that the operation of the entire hydrogen production system can be adaptively adjusted with the fluctuation of photovoltaic power generation, ensuring the full utilization of electricity and the maximization of hydrogen production efficiency, improving the rationality of electricity use, and thus helping to improve hydrogen production efficiency and energy utilization efficiency.

[0106] Optionally, in an implementation of this embodiment, regulating the operating states of multiple electrolytic cells and / or operating parameters of operating electrolytic cells according to fluctuations in power generation parameters includes:

[0107] Use the preset multi-objective optimization model to process the fluctuation of power generation parameters and obtain the multi-objective control results;

[0108] The operating states of multiple electrolytic cells and / or operating parameters of the electrolytic cells in operation are regulated according to the multi-objective regulation results.

[0109] Among them, the multi-objective control results include control results for at least two of the operating number of the electrolytic cell, water supply temperature, water supply pressure, water supply flow, electrolysis current and electrolysis power.

[0110] Among them, the multi-objective optimization model can be a neural network model or a combination of multiple models, and this embodiment does not specifically limit this. The purpose is to obtain the target control result according to the fluctuation of power generation parameters. In other words, the multi-objective optimization model can calculate the electrolytic cells that need to be operated and shut down, and calculate the operating parameters of the electrolytic cells in operation according to the amplitude of the electrical parameters, the trend of electrical parameter changes, and the time point of change of the trend of changes in the power generation parameters, so that the operating parameters of the electrolytic cells that are finally operated do not exceed the upper limit of the amplitude range in the power generation parameter fluctuation and are closest to the upper limit.

[0111] By adopting this embodiment, a multi-objective optimization model is used to realize the regulation of the electrolytic cell, which helps to improve the intelligence and efficiency of the regulation.

[0112] Optionally, in an implementation of this embodiment, the method further includes:

[0113] Obtain weather data corresponding to the target time period in the weather forecast data;

[0114] The weather data is processed using a preset prediction model to obtain multiple predicted power generation parameters for the target time period.

[0115] Shanghai 2024-11478 (M240483CNI)

[0116] The prediction model may be a neural network model or a combination of multiple models, which is not specifically limited in this embodiment, and is intended to be able to predict multiple predicted power generation parameters for a target time period based on weather data. For example, the prediction model is trained using historical weather data and historical power generation parameters, so that the prediction model can output predicted power generation parameters that are the same as the corresponding historical power generation parameters based on the historical weather data.

[0117] By adopting this implementation method, weather forecast data is used to predict power generation parameters, which helps to save costs.

[0118] Optionally, in an implementation of this embodiment, as Figure 3 As shown, after the weather data is processed using a preset prediction model to obtain a plurality of predicted power generation parameters for a target time period, the method further includes:

[0119] S300: Obtain reference weather data corresponding to a reference time period in the weather forecast data.

[0120] The reference time period is before the target time period. Preferably, the end time point of the reference time period is the same as the start time point of the target time period.

[0121] S302: Process reference weather data using a prediction model to obtain reference power generation parameters.

[0122] S304: Acquire actual power generation parameters in a reference time period.

[0123] S306: Compare the difference between the reference power generation parameter and the actual power generation parameter with the actual power generation parameter to obtain a correction ratio.

[0124] S308: Correct each predicted power generation parameter using the correction ratio to determine the power generation parameter fluctuation of photovoltaic power generation according to the corrected multiple predicted power generation parameters.

[0125] By adopting this implementation method, after obtaining the correction ratio through the actual power generation parameters, the predicted power generation parameters are corrected, which helps to improve the accuracy of the predicted power generation parameters when the weather forecast data is inaccurate.

[0126] Optionally, in an implementation of this embodiment, after regulating the operating states of the plurality of electrolytic cells and / or the operating parameters of the electrolytic cells in operation according to the fluctuation of the power generation parameters, the method further includes:

[0127] Obtaining the hydrogen demand in the target time period and the total hydrogen production of the electrolyzers in operation in the target time period;

[0128] If the hydrogen demand exceeds the total hydrogen production, the difference between the hydrogen demand and the total hydrogen production will be calculated. Shanghai 2024-11478 (M240483CNI)

[0129] The utility power is transferred to the shut down electrolytic cell to make the shut down electrolytic cell operate.

[0130] By adopting this implementation method, since the electrolytic cell is regulated first, the electric energy of photovoltaic power generation is fully utilized, and then the mains electricity is adjusted to easily reduce the use of mains electricity.

[0131] Optionally, in an implementation of this embodiment, before calling the mains power to the closed electrolyzer according to the difference between the hydrogen demand and the total hydrogen production to operate the closed electrolyzer, the method further includes:

[0132] Predicting the amount of photovoltaic power generation during the compensation period after the target period;

[0133] If the electric energy generated by the luminous power generation during the compensation time period satisfies the difference between the hydrogen production demand and the total hydrogen production, the operating status of multiple electrolytic cells and / or the operating parameters of the electrolytic cells in operation are regulated during the compensation time period according to the difference, and the call for mains electricity is cancelled.

[0134] That is to say, if the hydrogen production in the target time period cannot meet the hydrogen demand, it is predicted whether the photovoltaic power generation in the compensation time period can produce more hydrogen equal to the difference on the basis of meeting the original hydrogen production demand. If so, the city electricity will no longer be called.

[0135] The implementation method can maximize the use of photovoltaic power generation, save energy, protect the environment, adapt to the volatility of photovoltaic power generation, meet flexible production, and reduce costs.

[0136] The method embodiment according to the present application is described above by way of example.
