Abstract

In the present scenario, the grid connected renewable energy sources are playing an important role in meeting the peak power demand and providing quality of supply. One of the most favorable renewable energy sources with reasonable cost for producing the power is a solar photovoltaic system, which converts the solar power into the electrical power. The proposed work deals with a detail modeling of Grid connected solar photovoltaic system. The maximum power from the solar photovoltaic system is extracted using incremental conductance methods under dynamic variations in irradiance and temperature. The extracted power is integrated with the grid through the inverter using a hysteresis current control technique with the PI controller. The inverter and controller are used for providing quality of power supply and can meet the necessary peak demand. Under the dynamic irradiance and the temperature variations in the performance of the grid connected solar photovoltaic system is simulated in MATLAB-SIMULINK software.
