【 摘 要 】

Among many renewable energy sources, solar energy is widely used, and photovoltaic power generation has become an effective way of solar energy utilization. In recent years, it has been widely studied and applied, and remarkable results have been achieved. However, due to the influence of sunlight intensity and temperature, the power of the photovoltaic power generation is relatively fluctuating, so there are still some problems in large-scale grid-connection technology. In this paper, to direct at the power fluctuation of photovoltaic power generation caused by the change of illumination intensity and temperature, an energy storage photovoltaic grid-connected power generation system was proposed. A simulation model of photovoltaic power generation system based on mixed energy storage system was built in MATLAB/Simulink, and relevant simulation analysis and researches were conducted.
