Simulation Modeling of Photovoltaic Power Generation System and Analysis of Photovoltaic Shielding Power Generation Efficiency

Based on the actual operation data of micro grid photovoltaic power generation of the Central Research Institute of Shanghai Electric Group Co., Ltd., the simulink simulation model of photovoltaic system is established through Matlab. By adjusting the parameters of photovoltaic system, a photovoltaic array simulation model is built based on theory. Through the shielding test, explore the impact of shielding on photovoltaic power generation efficiency. Finally, by comparing the photovoltaic simulation results with the actual operation data of the photovoltaic system, the parameters of the photovoltaic power generation system are modified, which provides a reference for the operation of the micro grid system of the Central Research Institute.
