Study on Grid Connected Photovoltaic System Using PSIM Program

At the present, the renewable power systems are quickly developing in many countries to replace the fossil power sources and mitigate the environment pollution. Grid-tied solar power system is one of the most promising as a renewable energy technology but solar panels are dependent on sunlight to effectively gather solar energy. Technical innovations in solar power sector would allow investors to reduce the costs of installation and operation. Understanding the structure of grid-tie inverter technologies could affect on the costs of investment and operation as well as the efficiency of solar power plants. This paper presents a simulation model of single phase grid connected photovoltaic system in PSIM software.
