Upgrading Power Quality of a Distributed Generation Power System

M.Tech Research Scholar, Priyadarshini Institute of Technology & Management
Associate Professor, Priyadarshini Institute of Technology & Management

This paper 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 paper proposes the structure of the designed controller consists of output power with voltage control.
