[0033] The sensing module 100 collects various parameters and real-time local environmental information of the wind power generation module 610, the photovoltaic power generation module 620, the energy storage module 630, the hydrogen production module 710 and the hydrogen storage module 720 and transmits them upward through the network module 200; at the same time, the network module 200 is connected to the Internet, obtains real-time weather environment forecast parameters through the Internet and transmits them to the data module 300.

[0034] The data module 300 transmits the transmitted operating parameters, weather environment parameters and historical weather environment data of the same period to the management module 500 through the application module 400, and at the same time stores the parameters and weather environment parameters transmitted from the data layer in the storage medium in the data module 300 after preprocessing.

[0035] After receiving the data transmitted by the data module 300, the application module 400 makes judgments and analyses and controls the wind power generation module 610, the photovoltaic power generation module 620, the energy storage module 630, the hydrogen production module 710 and the hydrogen storage module 720 in real time according to the preset control instructions, and intelligently analyzes, judges and predicts the operating status of the entire hydrogen production management system. When the power status of the wind power generation module 610, the photovoltaic power generation module 620, the energy storage module 630, the hydrogen production module 710 or the hydrogen storage module 720 is monitored or predicted to change, the intelligent The system control instructions are issued to make reasonable adjustments to the operating states of the wind power generation module 610, the photovoltaic power generation module 620, the energy storage module 630, the hydrogen production module 710 and the hydrogen storage module 720, so as to realize intelligent and friendly interaction among the wind power generation module 610, the photovoltaic power generation module 620, the energy storage module 630, the hydrogen production module 710 and the hydrogen storage module 720 to ensure the balance of energy supply, transmission and consumption among the wind power generation module 610, the photovoltaic power generation module 620, the energy storage module 630, the hydrogen production module 710 and the hydrogen storage module 720.

[0036] As the highest management, analysis, monitoring, prediction and decision-making level, the management module 500 has the functions of obtaining system operation data, displaying system operation status, obtaining, monitoring and judging the control status and instructions of the application module 400, ensuring the safe, continuous and stable operation of the entire off-grid hydrogen production system, and controlling the application module 400 to make calculations and decisions based on real-time operation information. The management module 500 is also used to visualize the working status of the wind power generation module 610, the photovoltaic power generation module 620, the energy storage module 630, the hydrogen production module 710 and the hydrogen storage module 720, and provide the staff with reading and judgment. The management module 500 receives the manual decision input by the staff, sends the manual decision to the application module 400, and controls the application module 400 to adjust the real-time control instructions according to the manual decision.

[0037] In a specific embodiment, the sensing module 100 includes a plurality of hydrogen concentration monitors, which are respectively arranged on the outside of the hydrogen production module 720 and the hydrogen storage module 710. The hydrogen concentration monitors are used to respectively obtain the hydrogen concentration around the hydrogen production of the hydrogen production module 710 and the hydrogen storage of the hydrogen storage module 720. When the hydrogen concentration around the hydrogen production or the hydrogen storage is greater than a certain threshold, it is judged that the hydrogen production module 710 or the hydrogen storage module 720 may have a hydrogen leakage point. At this time, the application module 400 immediately starts the safety management and control program for the hydrogen production module 710 and the hydrogen storage module 720 to avoid production accidents. If the hydrogen concentration monitor at the hydrogen production module 710 detects that the hydrogen concentration around the hydrogen production is greater than a specific threshold value, the hydrogen concentration monitor alarms, and the application module 400 immediately shuts down the hydrogen production equipment corresponding to the alarm of the hydrogen concentration monitor that is alarming, and performs a safety inspection on it. After the problem is identified and repaired, the staff issues a manual decision, and the application module 400 can restart the above-mentioned hydrogen production equipment; if the hydrogen concentration monitor at the hydrogen storage module 720 detects that the hydrogen concentration around the hydrogen storage is greater than a specific threshold value, the hydrogen concentration monitor alarms, and the application module 400 immediately shuts down the hydrogen storage equipment corresponding to the alarming hydrogen concentration monitor, and performs a safety inspection on it. After the problem is identified and repaired, the staff issues a manual decision, and the application module 400 can restart the above-mentioned hydrogen storage equipment.

[0038] In addition, refer to Figure 5 As shown, in some embodiments of the present application, the local environment information includes real-time local weather information, the network environment information includes real-time network weather information, and the management module 500 is used to predict future weather conditions based on the historical weather data, real-time local weather information and network weather information stored in the data module 300, and determine control instructions based on future weather conditions, the working status of the energy supply module 600 and the working status of the load module 700.

[0039] Online weather information includes but is not limited to local wind speed, wind direction, light intensity, light radiation angle, temperature, humidity, visibility, atmospheric pressure, cloud cover, fog, sandstorms, severe convection, rainfall / snow / amount, rainfall duration, hail, lightning, etc.

[0040] Specifically, the network module 200 is connected to the Internet. The network module 200 obtains real-time network weather information and weather forecasts for a period of time in the future through the Internet at a preset weather sensing frequency. The network module 200 sends the current network weather information and the weather forecast for a period of time in the future to the data module 300, which stores the information and overwrites the weather forecast for the same time in the data module 300 based on the current network weather information and real-time local weather information.

[0041] In addition, the sensing module 100 is provided with a thermometer, a hygrometer, a wind vane, an air volume meter and a light sensor. The sensing module 100 obtains local weather information through the thermometer, the hygrometer, the wind vane and the air volume meter at a preset weather sensing frequency, and uploads the local weather information to the data module 300, which is stored by the data module 300.

[0042] Specifically, the application module 400 obtains historical weather data, the latest network weather information, the weather forecast for a period of time in the future, and the latest local weather information, and numerically quantifies the historical weather data, the latest network weather information, the weather forecast for a period of time in the future, and the latest local weather information. The greater the adverse effect of the weather information on the energy supply module 600 or the load module 700, the greater the corresponding numerical value. Different numerical weights are assigned to the numerical values ​​obtained by quantifying the historical weather data, the latest network weather information, the weather forecast for a period of time in the future, and the latest local weather information, so as to determine the weather forecast for the future. When the future weather condition is less than the preset first weather threshold, it means that the future weather condition in the next period of time is relatively good, supporting the energy supply module 600 and the load module 700 to operate at the highest power, and supporting the photovoltaic power generation module 620 and the wind power generation module 610 to supply power to the energy storage module 630; when the future weather condition is greater than the preset first weather threshold and less than the preset second weather threshold, where the first weather threshold is less than the second weather threshold, it means that the photovoltaic power generation module 620 and the wind power generation module 610 have poor utilization effect and efficiency of renewable resources, then based on the real-time power in the energy storage module 630, the energy storage module 630 is controlled. 0 supplies power to the hydrogen production module 710 with a specific real-time discharge power, or appropriately reduces the hydrogen production power of the hydrogen production module 710 based on the hydrogen storage capacity in the hydrogen storage module 720; when the future weather condition is greater than the second weather threshold, it means that the photovoltaic power generation module 620 and the wind power generation module 610 cannot operate normally under the current weather conditions. In the absence of manual intervention, the photovoltaic power generation module 620 and the wind power generation module 610 need to be shut down to ensure their safety. At the same time, the application module 400 predicts the duration of the future weather condition, combines the real-time power of the energy storage module 630 and the hydrogen storage capacity of the hydrogen storage module 720, and determines the duration of the weather condition. The real-time discharge power of the internal energy storage module 630 and the hydrogen production power of the hydrogen production module 710 are used to ensure that the hydrogen production module 710 can produce hydrogen stably to the maximum extent. When the staff inputs the manual control instruction, the application module 400 controls the load module 700 and the energy supply module 600 according to the manual control instruction through the sensing module 100. At the same time, the data module 300 stores the manual control instruction as a historical instruction. When the application module 400 determines the same or similar weather conditions again and there is no staff intervention, the application module 400 will execute the manual control instruction again to control the load module 700 and the energy supply module 600.

[0043] Exemplarily, during the day when the light intensity and wind speed are sufficient, the photovoltaic power generation module 620 is controlled to generate electricity at the photovoltaic rated power, and the wind power generation module 610 is controlled to generate electricity at the wind rated power, the energy storage module 630 is controlled to charge until the real-time power of the energy storage module 630 is equal to the energy storage capacity, and the hydrogen production module 710 is controlled to produce hydrogen at the highest available or rated power until the quality of the hydrogen stored in the hydrogen storage module 720 reaches the threshold; when the weather conditions are poor and the sum of the photovoltaic power generation power of the photovoltaic power generation module 620 and the wind power generation power of the wind power generation module 610 is less than the rated maximum power of the hydrogen production module 710, the real-time power of the energy storage module 630 and the quality of the hydrogen stored in the hydrogen storage module 720 are obtained, the duration of the current weather conditions is predicted, the minimum hydrogen production power of the hydrogen production module 710 is determined according to the current hydrogen demand of the hydrogen storage module 720, and the photovoltaic power generation module 620, the wind power generation module 610 and the energy storage module 630 are controlled to supply power to the hydrogen production module 710 at the same time.

[0044] In addition, refer again Figure 5 As shown, in some embodiments of the present application, a trained environmental prediction model is provided in the application module 400. The application module 400 inputs the historical weather data in the data module 300, the real-time weather information on site, and the network weather information acquired in real time by the network module 200 into the environmental prediction model to obtain future environmental conditions. The application module 400 determines control instructions according to the future environmental conditions, the working status of the energy supply module 600, and the working status of the load module 700.

[0045] Specifically, according to the actual geographical environment where the photovoltaic power generation module 620, the wind power generation module 610 and the hydrogen production module 710 are located, geographical parameters are preset in the environmental prediction model; the application module 400 inputs the historical weather data in the data module 300 and the network weather information acquired in real time by the network module 200 into the environmental prediction model, and the environmental prediction model predicts the wind power generation power and photovoltaic power generation power of the wind power generation module 610 and the photovoltaic power generation module 620 within a certain period of time according to the wind direction and volume and solar illumination within a certain period of time in the above weather information. The model also obtains the real-time power of the energy storage module 630 and the quality of the hydrogen stored in the hydrogen storage module 720, predicts the remaining usable time of the energy storage module 630 and the hydrogen storage module 720, and plans the real-time charging power or real-time discharging power of the energy storage module 630 and the hydrogen production power of the hydrogen production module 710 according to the predicted remaining usable time, wind power generation power and photovoltaic power generation power; similarly, if the staff performs manual intervention within the predicted time period, the working status of the energy supply module 600 and the energy storage module 630 is controlled based on the manual control instructions.

[0046] In a specific embodiment, the input of the environmental prediction model also includes local weather information detected by the perception module 100. The environmental prediction model combines the network weather information with the actual geographical environment, determines the wind direction, wind volume and solar illumination under the influence of the network weather information, and combines the wind direction, wind volume and solar illumination measured by the local weather information to predict the wind power generation power and photovoltaic power generation power of the wind power generation module 610 and the photovoltaic power generation module 620 within a certain period of time.

[0047] Specifically, after inputting local weather information and network weather information, the environmental prediction module determines the future environmental conditions based on the local weather information and network weather information. The future environmental conditions include the wind volume curve of the area where the hydrogen production system is located and the cloud cover curve above it. The wind efficiency curve can be determined based on the wind volume curve. By integrating the wind volume curve or the wind efficiency curve, the wind power generation of the wind power generation module 610 within a certain period of time can be predicted. In addition, based on the cloud cover curve and its time axis, the longitude and latitude of the area where the hydrogen production system is located are obtained, and its illumination curve can be obtained. Based on the illumination curve, the light efficiency curve can be determined. By integrating the illumination curve or the light efficiency curve, the light power generation of the photovoltaic power generation module 620 within a certain period of time can be predicted.

[0048] The application module 400 determines the available power of renewable resources within a certain period of time based on the wind power generation and the solar power generation. The application module 400 determines the maximum hydrogen production within a certain period of time based on the hydrogen production efficiency of the hydrogen production module 710. The first hydrogen production amount that meets the hydrogen demand and fills the hydrogen storage system to the maximum hydrogen storage is determined based on the prediction of the hydrogen demand within a certain period of time, and the hydrogen quality and hydrogen storage capacity of the hydrogen storage system. If the maximum hydrogen production amount is greater than the first hydrogen production amount, the difference between the maximum hydrogen production amount and the first hydrogen production amount is calculated, and the remaining power generation is reversed based on the above difference, and this part of the remaining power generation is stored in the energy storage module 630; if the maximum hydrogen production amount is less than or equal to the first hydrogen production, the wind power generation and solar power generation within a certain period of time are controlled to be supplied to the hydrogen production module 710, the difference between the maximum hydrogen production amount and the first hydrogen production amount is calculated, and the power required for energy storage is determined based on the above difference, and the power required for energy storage will be supplied by the energy storage module 630.

[0049] In addition, the wind efficiency curve and the light efficiency curve are determined in the environmental prediction model. According to the specific parameters of the wind power generation module 610 and the photovoltaic power generation module 620, the wind power curve of the wind power generation module 610 within a certain period of time and the photovoltaic power curve of the photovoltaic power generation module 620 within a certain period of time can be determined respectively. According to the wind power curve and the photovoltaic power curve, the renewable resource power curve within a certain period of time is determined. When the current control strategy of the application module 400 is to give priority to hydrogen production, the application module 400 obtains the rated hydrogen production power of the hydrogen production module 710. When the renewable resource power curve is If the renewable resource power value at a certain point in time, that is, the sum of the wind power curve and the photovoltaic power curve at a certain point in time is greater than the rated hydrogen production power, then at this point in time, the sum of the powers output by the wind power generation module 610 and the photovoltaic power generation module 620 to the hydrogen production module 710 is controlled to be equal to the rated hydrogen production power. At the same time, the remaining power value of the renewable resource power and the rated hydrogen production power is calculated, and the sum of the powers output by the wind power generation module 610 and the photovoltaic power generation module 620 to the energy storage module 630 is controlled to be equal to the remaining power value, thereby avoiding damage to the hydrogen production module 710 due to excessive hydrogen production power.

[0050] In addition, when the current control strategy of the application module 400 is to prioritize energy storage, the application module 400 obtains the rated charging power of the energy storage module 630. When the renewable resource power value is greater than the rated charging power of the energy storage at a certain point in time, the wind power generation module 610 and the photovoltaic power generation module 620 are controlled to output the sum of the powers to the energy storage module 630 equal to the rated charging power of the energy storage. At the same time, the remaining power value of the renewable resource power and the rated charging power of the energy storage is calculated, and the sum of the powers output by the wind power generation module 610 and the photovoltaic power generation module 620 to the hydrogen production module 710 is controlled to be equal to the remaining power value, which can also avoid damage to the energy storage module 630 due to excessive energy storage power.

[0051] In addition, in some embodiments of the present application, when local environmental information and network environmental information meet preset severe environmental conditions, the application module 400 determines the first photovoltaic safety power and the first wind safety power according to the environmental information, and the application module 400 predicts the duration of the current environmental information, obtains the real-time power of the energy storage module 630 and the hydrogen storage quality of the hydrogen storage module 720, determines the first hydrogen production safety power according to the first photovoltaic safety power, the first wind safety power, the duration, the real-time power and the hydrogen storage quality, gradually reduces the photovoltaic power generation power of the photovoltaic power generation module 620 to the first photovoltaic safety power, gradually reduces the wind power generation power of the wind power generation module 610 to the first wind safety power, and gradually reduces the hydrogen production power to the first hydrogen production safety power.

[0052] In a specific embodiment, when the environmental information within a time period meets the severe environmental conditions, the perception module 100 controls the wind power generation module 610 to lower the height of the wind turbine, and gradually controls the wind turbine to be turned off or on according to the local weather information obtained by real-time measurement. The perception module 100 obtains the cut-in wind speed and cut-out wind speed on the wind turbine blades in real time, and adjusts the angle of the wind turbine blades according to the cut-in wind speed and the cut-out wind speed, thereby adjusting the wind power generation power of the wind power generation module 610 to the first wind safety power; the perception module 100 gradually controls the photovoltaic components to be turned off or on according to the local weather information obtained by real-time measurement, and shields or stores the closed photovoltaic components, thereby preventing the harsh environment from causing damage to the photovoltaic components.

[0053] It should be noted that the first wind safety power, the first photovoltaic safety power and the first hydrogen production safety power can be set to 0.

[0054] In a specific embodiment, in a harsh environment, when the first wind safety power and the first photovoltaic safety power are both 0, the hydrogen production module 710 will be powered by the energy storage module 630, and the application module 400 determines the adjustment coefficient based on the current environmental information, and gradually adjusts the hydrogen production power of the hydrogen production module 710 and the discharge power of the energy storage module 630 to the first hydrogen production safety power according to the adjustment coefficient.

[0055] It should be noted that severe environmental conditions include but are not limited to disaster weather such as sandstorms, severe convection, heavy rain, heavy fog, hail, lightning, etc.

[0057] In a specific embodiment, when the environmental information within a time period meets the safety environment conditions, the perception module 100 obtains the cut-in wind speed and the cut-out wind speed on the wind turbine blades in real time, adjusts the angle of the wind turbine blades according to the cut-in wind speed and the cut-out wind speed, and the perception module 100 gradually increases the height of the wind turbine, thereby adjusting the wind power generation power to the second wind safety power; the perception module 100 obtains the real-time light intensity, gradually starts and restores the operation of the photovoltaic components, thereby adjusting the photovoltaic power generation power to the second photovoltaic safety power.

[0059] Specifically, the hydrogen production pressure is used to indicate the hydrogen inventory in the hydrogen production module 710, and the hydrogen storage mass is used to indicate the hydrogen inventory in the hydrogen storage module 720. The application module 400 predicts the usable time of the hydrogen stored in the load module 700 in real time based on the hydrogen demand, the hydrogen production pressure of the hydrogen production module 710 and the hydrogen storage mass of the hydrogen storage module 720. When the usable time is less than the preset time threshold, the application module 400 controls the energy storage module 630 to increase the real-time discharge power of the hydrogen production module 710 to improve the hydrogen production power of the hydrogen production module 710.

[0060] In addition, when the usable time is less than the preset time threshold and the real-time charging power of the energy storage module 630 is greater than 0, the application module 400 controls the reduction of the real-time charging power of the energy storage module 630, and controls the photovoltaic power generation module 620 and the wind power generation module 610 to increase the power supply to the hydrogen production module 710.
