Simulation and analysis of grid connected photovoltaic system with MPPT

In this paper a different approach for evaluating the performance of Photovoltaic Array is presented and grid connected DC-AC converter control topology is implemented. A model is developed through converting basic circuit equation of solar cell into simplified form including the effect of changing solar irradiation and temperature. This paper proposes an efficient MPPT control approach and grid interfacing of Photovoltaic array through DC/DC/AC Converter. The proposed system is modeled and simulated in MATLAB Simulink environment. An extensive simulation study is carried out to validate the proposed control approach.
