Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a coupled power generation system and method shared by photovoltaic and energy storage components. Background technique [0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. Photovoltaic power generation is an important direction for the development of clean energy in the future, and various countries are vigorously developing it. [0003] The electricity generated by photovoltaic power generation needs to be connected to the grid to be used. Grid-connected photovoltaic power generation means that the direct current generated by photovoltaic modules is converted into alternating current that meets the requirements of the grid through a grid-connected inverter and then connected to the public grid. However, photovoltaic powe...
