Power Quality Improvement of Grid Connected Solar System

Abstract

The need to generate pollution free energy has triggered the effect towards the usage of solar energy interconnection with the grid. Consequently, the Photovoltaic [PV] panel interfaced with the grid causes the power quality problems such as a harmonics, voltage sag etc., Active power filters are the powerful tool for mitigation of harmonics. This proposed work describes the methodology for improving power quality of the grid interfaced with renewable energy. The inverter used in this methodology can also be used as a power converter for injecting power from solar to grid along with harmonic compensation. The proposed concept is validated through dynamic simulation using MATLAB/Simulink Power system toolbox.
