[0059] In the case where power is supplied to users at the electricity consumption end only through the energy storage system, the power consumption and the storage capacity are compared. When it is determined that the storage capacity is not less than the power consumption, the lighting environment is judged according to the lighting environment data. When the light intensity in the lighting environment data is greater than the lighting threshold, it is determined that the current lighting environment is suitable for power generation, and instruction 2 is generated and sent to the photovoltaic power generation system. The photovoltaic power generation system continues to generate electricity and stores the electric energy in the power storage system through the filtering + isolation system until the energy storage system is fully loaded, stops generating electricity, and repeatedly receives the power consumption, storage capacity and lighting environment data, and performs real-time analysis and judgment on the latest received data.

The photovoltaic power generation system starts after receiving the instruction 2, and stores the electric energy generated by photovoltaic power generation in the power storage system through the filtering isolation system until the power storage system is fully loaded and stops generating electricity. When it is determined that there is a fault in the photovoltaic power generation system, a fault alarm is generated.

[0088] On the other hand, the power storage system sends data 1 to the data processing center in real time. The data processing center analyzes data 1. When the power storage amount is less than the power storage threshold, the data processing center generates instruction 1 and sends it to the power storage system. The power storage system starts after receiving instruction 1, and provides the electric energy stored in the power storage system to users through the inverter + filtering system, or provides it to the power grid through the boost filtering + isolation system, thereby increasing the benefits of local users.
