[0002] Solar photovoltaic power generation system is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes: independent operation and grid-connected operation. Independent photovoltaic power generation system requires batteries as energy storage devices, and is mainly used in remote areas without power grids and areas with dispersed populations. The cost of the entire system is very high. In areas with public power grids, photovoltaic power generation systems are connected to the power grid and run in parallel, eliminating batteries, which can not only significantly reduce costs, but also have higher power generation efficiency and better environmental performance.
