Improving the Power Quality Performance for Distributed Power Generation

Abstract

This project presents analysis and improvement of power quality (voltage sag, voltage swell ) performance of grid connected inverter used in distributed generation.The developed controller controls power supplied by the DGs at the PCC. The controller is designed to deliver current at unity power factor at PCC. An increase in reactive power demand and harmonics at PCC due to change of load and grid impedance variation, would affect the system voltage at PCC.This project proposes the structure of the designed controller consists of output power with voltage control
