Enhancement of power quality in microgrid using IPQC

Abstract

Distributed Energy Resources (DERs) has been emerging as a promising option to meet the growing customer electrical needs. It has an emphasis on reliabilities and environmentally friendly system. In this scenario, in order to maximize the operation efficiency of the DERs effective integration is needed. It enhances the local customer power supply reliability, system performance and minimizes the system losses. Nowadays with increasing demand on a day to day life microgrid plays a vital role in electricity generation using renewable energy resources. A microgrid usually consists of multiple DERs interfaced to the system through power electronic devices. Usage of power electronic devices in microgrid results in the harmonic generation and leads to various power Quality issues. The main objective in a microgrid is to provide the quality of power to its interconnected inhabitants. In order to overcome harmonic high penetration, frequent voltage fluctuations and over current, a magnetic flux control based variable reactor is proposed. The performance of the variable reactor and integrated power quality controller (IPQC) can be designed and verified by using MATLAB/SIMULINK
