[0002] Solar photovoltaic power generation has always been an important part of my country's strategy to achieve sustainable development of energy and electricity. The photovoltaic energy storage system can store the electricity from the photovoltaic power station in the energy storage battery. When the photovoltaic power generation is lower than the limit value or when the electricity consumption is at peak at night, the energy storage inverter will be used to send the electricity in the battery to the power grid. The energy storage system participates in peak shaving and valley filling of the power grid.

[0003] Energy storage systems can also use the difference in peak and valley electricity prices to create greater economic benefits and improve the system's own regulation capabilities, serving as an effective supporting technology for solving the problem of large-scale renewable energy generation access to the grid.
