Power Quality Improvement in Ten-Bus Distribution System Using Distributed Unified Power Quality Conditioner

Abstract

This work presents closed-loop results of DUPQC in Ten-Bus Distribution System (TBDS). Multiple DUPQCs have been used as a FACTS controller between sending-end-bus and receiving-end-bus. The goal of the suggested DUPQC system is to enhance the voltage and reduce THD using multiple DUPQCs. Block diagrams and Simulink models are developed for PI and FOPID controlled TBDS using two DUPQCs. Simulation studies are performed on DUPQC based TBDS and the results are presented. The results of bus voltages of PI and FOPID based TBD systems indicate that the time response with FOPID is superior to PI controlled TBDS.
