Power Quality Improvement of Single Phase Grid Connected Photo Voltaic System

Abstract

Power quality which involves power factor and the current wave form mainly affected by the power electronic loads which are connected to the grid. In this work reactive power compensation theory is applied to the inverter which feeds the power to the grid from the solar grid. Solar cell works on the principle of photo voltaic effect, which has nonlinear voltage and current characteristics. These characteristics are improved with the help of maximum power point tracking (MPPT) controller. MPPT controller helps to feed the inverter with maximum power from the solar grid. The Mat lab/Simulink model for the photo voltaic cell are implemented, MPPT controller has been modeled for driving the boost converter. MATLAB/simulation results are verified for the single phase grid involves the current waveform and total harmonic distortion level.
