[0019] In some embodiments of the present application, see Figure 1 As shown, this embodiment provides a factory clean power generation system, including: Photovoltaic power generation system, hydrogen power generation system, energy storage system, power distribution system and intelligent energy supply system; among them, The photovoltaic power generation system is connected to the hydrogen power generation system, the energy storage system and the intelligent energy supply system respectively. The photovoltaic power generation system converts solar energy into electrical energy through a photovoltaic power generation device. The photovoltaic power generation system is used to transmit electrical energy to the hydrogen power generation system and the energy storage system.

[0020] It is understandable that the present invention alleviates the dilemma of insufficient peak power quotas in factories, and helps factories achieve sustainable development. Photovoltaic power generation systems can be used to store electricity on the one hand, and to produce hydrogen through water electrolysis on the other hand, thereby realizing hydrogen power generation. The smart energy supply system realizes the intelligent coordination of the power distribution system, thereby ensuring the stability and safety of the factory's power supply. The present invention combines the efficient use of solar energy and hydrogen energy to reduce part of the carbon emissions in industrial production, and at the same time provides enterprises with a smart clean energy power supply solution, which is particularly important in the context of environmental protection and clean production.

[0021] Specifically, the photovoltaic power generation system can adopt the roof photovoltaic laying method, laying a large number of photovoltaic panels on the top of the factory building and installing solar trackers to improve the utilization rate of solar energy. The electricity of the photovoltaic power generation system directly supplies power to the hydrogen power generation system to produce hydrogen energy. The fuel cell in the hydrogen power generation system adopts a proton exchange membrane fuel cell, which has a low operating temperature and high efficiency. The hydrogen storage method adopts a simple and direct high-pressure gas storage. In the energy storage system, the electricity from photovoltaic and hydrogen energy is stored in lithium iron phosphate batteries. Its high safety, stable charging and discharging, long life, low cost and environmental friendliness are suitable for clean energy storage. The smart energy supply system needs to collect and process the status data of the photovoltaic power generation system, hydrogen power generation system and energy storage system, and distribute and diagnose the electricity. Thereby ensuring the stability and coordination of the functions in the factory. After receiving the command of the smart energy supply system, the power distribution system distributes the existing electricity to the power demand areas in the factory, such as lighting, battery car charging, data center backup power charging and other usage scenarios.

[0022] In some embodiments of the present application, the photovoltaic power generation system includes: Photovoltaic array, battery controller and solar tracking controller; among them, The photovoltaic array is composed of a plurality of solar panels, and the photovoltaic array is used to convert solar energy into electrical energy; The battery controller is used to store the electric energy generated by the photovoltaic array to provide power at night or when there is insufficient light; The solar tracking controller is used to keep the photovoltaic array aligned with the sun to improve the efficiency of receiving solar energy.

[0023] In some embodiments of the present application, the hydrogen power generation system includes: Hydrogen production equipment, hydrogen storage tanks and fuel cells; among which, The hydrogen production device is used to produce hydrogen through water electrolysis and electricity produced by a photovoltaic power generation system; The hydrogen storage tank is used to store hydrogen; The fuel cell is used to convert chemical energy into electrical energy through a chemical reaction of hydrogen and oxygen.

[0024] It is understandable that the factory clean power generation system of the present invention can make full use of renewable energy and improve energy efficiency by integrating photovoltaic power generation and hydrogen power generation technology. The photovoltaic array converts solar energy into electrical energy, and at the same time ensures maximum reception efficiency through the solar tracking controller. The battery controller stores excess electrical energy so that it can be powered at night or when there is insufficient light to ensure the stability of the system. The hydrogen power generation system uses the electricity generated by photovoltaic power generation through water electrolysis technology to produce hydrogen, which is stored in hydrogen storage tanks, and the hydrogen is converted into electrical energy through the reaction of hydrogen and oxygen through fuel cells. It not only improves the diversification and reliability of energy, but also effectively reduces dependence on traditional fossil energy, promotes the low-carbon, clean energy transformation of the factory, and enhances the flexibility and sustainability of energy supply, further improving the overall operating efficiency and economy of the system.

[0025] In some embodiments of the present application, the smart energy supply system is used to collect the power information of the photovoltaic power generation system, the hydrogen power generation system and the energy storage system, and control the distribution of power of the power distribution system according to the power information, including: Collecting electric energy information, wherein the electric energy information includes the power demand of the hydrogen power generation system, the power generation of the hydrogen power generation system, and the power generation of the photovoltaic power generation system; Calculate the sum of the power demand of the hydrogen power generation system and the power consumption of the factory power consumption area, and determine whether to use only the power generation of the photovoltaic power generation system to supply power to the factory power consumption area according to the sum; If it is determined that the power generation of the photovoltaic power generation system is not the only one to be used for power supply, the difference between the sum and the power generation of the photovoltaic power generation system is calculated, and based on the difference and the power generation of the hydrogen power generation system, it is determined whether the pre-stored power of the energy storage system is used to supply power to the power consumption area of ​​the factory; If it is determined that the pre-stored electricity of the energy storage system needs to be used for power supply, the pre-stored electricity is divided into a reserve power supply and a storage power supply, and the factory power consumption area is powered by the reserve power supply.

[0026] It is understandable that the present invention significantly improves the efficiency and flexibility of energy use by accurately monitoring and dynamically adjusting the distribution of electric energy. The system first collects electric energy information from the photovoltaic power generation system, the hydrogen power generation system and the energy storage system, and tracks the power demand, power generation and power generation of the hydrogen power generation system in real time. Based on these data, the intelligent energy supply system can calculate the power demand of the hydrogen power generation system and the total power consumption of the power consumption area of ​​the factory, and determine whether to rely solely on the power generation of the photovoltaic power generation system to supply power. If the power generation of the photovoltaic power generation system alone is insufficient, the system will further calculate the difference, and combine the power generation of the hydrogen power generation system to determine whether the power of the energy storage system needs to be mobilized. The intelligent energy supply system can not only ensure the continuous and stable power supply of the factory, but also reduce unnecessary energy waste while ensuring efficiency. The power of the energy storage system is intelligently divided into reserve power supply and storage power, so that the reserve power supply can be deployed in time during peak demand to ensure uninterrupted power supply in the factory. Through this method, the system makes full use of renewable energy and optimizes the use of the energy storage system, greatly improves energy utilization, reduces dependence on external energy, helps the factory achieve efficient and green energy management, and promotes low-carbon development.

[0027] In some embodiments of the present application, the calculation of the sum of the power demand of the hydrogen power generation system and the power consumption of the factory power consumption area, and judging whether to use only the power generation of the photovoltaic power generation system to supply power to the factory power consumption area according to the sum, includes: Setting a safety power value, and calculating a first power sum of the safety power value and the sum value; If the first power sum is less than the power generation of the photovoltaic power generation system, it is determined that only the power generation of the photovoltaic power generation system is used to supply power to the factory power consumption area; If the first power sum is greater than or equal to the power generation of the photovoltaic power generation system, it is determined that not only the power generation of the photovoltaic power generation system is used for power supply, but also the power generation of the hydrogen power generation system and the pre-stored power of the energy storage system are needed to supply power to the factory power consumption area.

[0028] In some embodiments of the present application, judging whether to use the pre-stored power of the energy storage system to supply power to the factory power consumption area according to the difference and the power generation of the hydrogen power generation system includes: Calculate a second electric quantity sum of the difference and the safety electric quantity value; If the second power sum is less than the power generation of the hydrogen power generation system, the power generation of the hydrogen power generation system and the power generation of the photovoltaic power generation system are used to supply power to the power consumption area of ​​the factory at the same time; If the second power sum is greater than or equal to the power generation of the hydrogen power generation system, the power generation of the hydrogen power generation system, the power generation of the photovoltaic power generation system and the pre-stored power of the energy storage system are used to supply power to the factory power consumption area.

[0029] It can be understood that the present invention intelligently optimizes the power supply strategy of the factory power consumption area by setting a safe power value and combining it with the real-time power demand, significantly improving the flexibility and reliability of energy scheduling. First, by calculating the sum of the power demand of the hydrogen power generation system and the power consumption of the factory, and comparing it with the power generation of the photovoltaic power generation system, the system can determine whether to rely solely on the photovoltaic power generation system for power supply. By setting the safe power value as a reserved guarantee, it is ensured that there is still enough power to maintain the stability of power supply even in the case of insufficient photovoltaic power generation. If photovoltaic power generation is not enough to fully meet the demand, the system further calculates the difference and compares it with the power generation of the hydrogen power generation system to determine whether to mobilize the pre-stored power of the energy storage system. This hierarchical power distribution scheme can minimize the burden on the energy storage system, avoid over-reliance on energy storage, and thus extend the service life of the energy storage equipment. The present invention promotes green and low-carbon energy management and ensures the efficiency, reliability and sustainability of factory energy supply.

[0030] In some embodiments of the present application, if it is determined that the pre-stored power of the energy storage system needs to be used for power supply, the pre-stored power is divided into a reserve power supply and a storage power, including: The second electric quantity is calculated and the electric quantity difference with the electric quantity produced by the hydrogen power generation system is calculated, the similarity between the electric quantity difference and the historical electric quantity difference is calculated, and the reserve power supply and the electric quantity storage are divided according to the similarity.

[0031] In some embodiments of the present application, the dividing of the reserve power supply and the reserve power according to the similarity includes: A maximum similarity value and a minimum similarity value are set. If the similarity value is greater than or equal to the maximum similarity value, the average value of the historical reserve power supply is calculated, the average value of the historical reserve power supply is used as the reserve power supply, and other pre-stored power of the energy storage system is stored as the stored power; If the similarity is less than the maximum similarity value and greater than the minimum similarity value, the maximum historical reserve power supply amount is used as the reserve power supply amount, and other pre-stored power of the energy storage system is stored as the stored power amount; If the similarity is less than or equal to the minimum similarity value, the compensation power is calculated according to the power difference, and the standby power supply and storage power are divided according to the compensation power.

[0032] In some embodiments of the present application, if the similarity is less than or equal to the minimum similarity value, the compensation power is calculated by the power difference, and the standby power supply and the storage power are divided according to the compensation power, including: Comparing the power difference with the maximum value of the historical reserve power supply; If the compensation power is larger, the compensation power is the sum of the power difference and the safety power value; If the power difference is large, the compensation power is the sum of the safety power value and the historical reserve power supply.

[0033] In some embodiments of the present application, if the similarity is less than or equal to the minimum similarity value, the compensation power is calculated by the power difference, and the standby power supply and the storage power are divided according to the compensation power, including: The compensated electricity is used as the reserve power supply, and the other pre-stored electricity of the energy storage system is stored as the stored electricity.

[0034] It can be understood that the present invention effectively optimizes the energy use and power distribution of the energy storage system by dynamically dividing the reserve power supply and storage capacity based on the power difference and the similarity of historical data. This similarity-based division strategy can flexibly adjust the reserve power supply and storage capacity according to the matching degree of historical data and current power difference, so as to better adapt to real-time energy demand. When the similarity is high, the system can accurately divide the reserve power supply and storage capacity according to the mean or maximum value of historical data, reduce the uncertainty of the system, and improve the stability of power supply; when the similarity is low, the system calculates the compensation power to make up for the power gap and ensure the continuity and reliability of power supply. Through this intelligent, data-driven scheduling method, the system can not only ensure the efficient use of reserved power when power demand fluctuates, but also ensure that the energy storage system is not over-consumed and prolong its service life. Overall, this allocation strategy not only optimizes the management of energy storage resources, improves the responsiveness and adaptability of the system, but also ensures the stable supply of power in the factory under various workloads, and further promotes the green, low-carbon and efficient energy management of the factory.
