The solar photovoltaic technology research based on PI control

With the development of solar photovoltaic power generation technology, photovoltaic power supply and grid-connected has become an important topic in the field of household power supply system. Based on the analysis of characteristics of solar photovoltaic power generation and power generation principle, this paper has an in-depth study on grid-connected inverter and solar inverter control technology, and puts forward the photovoltaic inverter system which is based on PI feedback control algorithm. through the results of the MATLAB simulation, it can be seen that the photovoltaic power generation system joined the PI feedback control algorithm can get the stable output current, and improves the steady state performance of inverter system.
