[0002] A grid-connected power generation system refers to connecting power generation equipment (such as solar panels, wind turbines, etc.) to the power grid so that the electricity it generates can be injected into the public power grid. This system enables distributed energy (such as distributed generation) to be integrated into the main power network to achieve energy sharing and utilization. The solar grid-connected power generation system converts solar energy into electrical energy and sends the electrical energy directly to the grid through a grid-connected inverter without battery storage.
