[0034] Step S2: Compare the power generation of the renewable energy device with the power demand of the load to obtain a comparison result.

[0035] Step S3: Based on the comparison result, the power of the energy storage battery and the reserve of hydrogen energy, a control strategy set is generated, wherein the control strategy set includes: controlling the energy storage battery to power the load, controlling the hydrogen fuel cell to power the load, the renewable energy equipment using the energy storage battery to store energy, and the renewable energy equipment using the water electrolysis hydrogen production equipment to store energy.

[0036] In an embodiment of the present application, the power generation power of the renewable energy device is compared with the power demand of the load, and a control strategy set is generated based on the comparison result, the power of the energy storage battery, and the hydrogen energy reserves, so that when the power generation power of the renewable energy device is insufficient, the energy storage battery and the hydrogen fuel cell are used to coordinate with the renewable energy device to power the load, and when the power generation power of the renewable energy device is sufficient, the remaining power is stored in the energy storage battery and / or hydrogen fuel cell, thereby ensuring that the distributed energy system provides stable power supply to the load.

[0037] In an exemplary embodiment of the present application, obtaining energy information of the energy system in step S1 includes the following steps:

[0038] Step S11: Collect environmental information, which includes light intensity and wind speed.

[0039] Step S12: Input the light intensity into the first deep reinforcement learning model to obtain the power generated by the solar panel.

[0040] It should be noted that multiple sets of light intensity and solar panel power generation under corresponding light intensity are collected, and the first machine model is selected and trained according to the light intensity and the solar panel power generation. Based on the trained first machine model, the first deep reinforcement learning model is obtained; the network parameters of the first deep reinforcement learning model are adjusted by using the reward function to update the first deep reinforcement learning model. Among them, the transfer learning technology is used to speed up the model training and convergence speed and improve the adaptability.

[0041] Step S13: Input the wind speed into the second deep reinforcement learning model to obtain the power generated by the wind turbine.

[0042] It should be noted that multiple sets of wind speeds and wind turbine power generation under corresponding wind speeds are collected, and the second machine model is selected and trained according to the wind speed and wind turbine power generation. Based on the trained second machine model, the second deep reinforcement learning model is obtained; the network parameters of the second deep reinforcement learning model are adjusted by using the reward function to update the second deep reinforcement learning model.

[0046] It should be noted that the load is an external power grid load. The power generation power of the renewable energy device is less than the power demand of the load, which means that the electricity generated by the renewable energy device cannot meet the power demand of the load. While the renewable energy device is supplying power, energy storage batteries and / or hydrogen fuel cells are required to assist in powering the load. Among them, the first preset power is calibrated according to actual demand. The first preset power refers to the remaining power after meeting the power demand of the energy storage battery itself. For example, 10% of the power of the energy storage battery is used for the energy storage battery's own consumption. Then, when the power of the energy storage battery is greater than 10%, it can power the load.

[0047] In an exemplary embodiment of the present application, in step S3, a control strategy set is generated based on the comparison result, the power of the energy storage battery and the reserve of hydrogen energy, including: when the power generation power of the renewable energy device is less than the required power of the load, judging whether the power of the energy storage battery is greater than a first preset power; if so, generating a second control strategy in the control strategy set, wherein the second control strategy is used to control the energy storage battery to power the load and to control the hydrogen fuel cell to power the load.

[0048] It should be noted that the load is an external power grid load. The power generation power of the renewable energy device is less than the power demand of the load, which means that the electric energy generated by the renewable energy device cannot meet the power demand of the load. While the renewable energy device is supplying power, energy storage batteries and / or hydrogen fuel cells are required to assist in powering the load. Among them, the first preset power is calibrated according to actual demand. The first preset power refers to the remaining power after meeting the power demand of the energy storage battery itself. For example, 10% of the power of the energy storage battery is used for the energy storage battery’s own consumption. Then, when the power of the energy storage battery is greater than 10%, it can power the load. In order to speed up the power supply, energy storage batteries and hydrogen fuel cells are used to power the load at the same time.

[0049] In an exemplary embodiment of the present application, in step S3, a control strategy set is generated based on the comparison result, the power of the energy storage battery and the reserve of hydrogen energy, and also includes: when the power generation power of the renewable energy device is less than the required power of the load and the power of the energy storage battery is less than or equal to the first preset power, a third control strategy in the control strategy set is generated, wherein the third control strategy is used to control the hydrogen fuel cell to power the load.

[0050] It should be noted that the load is an external power grid load. The power generation power of the renewable energy device is less than the required power of the load, which means that the electric energy generated by the renewable energy device cannot meet the power demand of the load. While the renewable energy device is supplying power, energy storage batteries and / or hydrogen fuel cells are required to assist in powering the load. Among them, the first preset power is calibrated according to actual demand. The first preset power refers to the remaining power after meeting the power demand of the energy storage battery itself. For example, 10% of the power of the energy storage battery is used for the energy storage battery's own consumption. If the power of the energy storage battery is less than or equal to 10%, it cannot supply power to the load. At this time, it is necessary to control the hydrogen fuel cell to supply power to the load.

[0051] In an exemplary embodiment of the present application, in step S2, a control strategy set is generated based on the comparison result, the power of the energy storage battery and the reserves of hydrogen energy, including: when the power generation power of the renewable energy device is greater than the required power of the load, judging whether the power of the energy storage battery is greater than or equal to the second preset power; if so, judging whether the reserves of hydrogen energy are less than the preset reserves; if so, generating a fourth control strategy in the control strategy set, wherein the fourth control strategy is used to control the renewable energy device to store energy using the water electrolysis hydrogen production equipment.

[0052] It should be noted that the load is the external power grid load. The power generation power of the renewable energy equipment is greater than the power demand of the load, which means that the electricity generated by the renewable energy equipment can meet the power demand of the load and there is still power left. At this time, the remaining power needs to be stored. Among them, the second preset power is calibrated according to actual needs. The second preset power refers to the power of the energy storage battery close to full power. If the energy storage battery is continuously charged, the energy storage battery will be overcharged. For example, the second preset power is 80%. The preset reserve is calibrated according to actual needs. The preset reserve refers to the hydrogen energy reserve close to a full tank. For example, the preset reserve is 80%. If the tank is continuously charged with hydrogen, it will exceed the rated pressure of the tank and cause damage to the tank.

[0053] Specifically, in the process of producing hydrogen by electrolysis of water, a large amount of heat is generated, which can be recovered. According to the fluctuation of the power generation of renewable energy equipment, the parameters of the electrolyzer are adjusted to improve the efficiency of hydrogen production and reduce energy consumption.

[0055] It should be noted that the load is an external power grid load. The power generation power of the renewable energy device is greater than the power demand of the load, which means that the electricity generated by the renewable energy device can meet the power demand of the load and there is still power left. At this time, the remaining power needs to be stored. Among them, the second preset power is calibrated according to actual needs. The second preset power refers to the power of the energy storage battery close to full power. If the energy storage battery is continuously charged, it will cause the energy storage battery to be overcharged. Then when the power of the energy storage battery is less than the second preset power, the energy storage battery can be charged.
