Power Quality Improvement in Grid Interfaced system using Fuzzy-UPQC Controller

Abstract

The main aim of this paper is to enhance the power quality problems for micro grid system. A flexible ac distribution system is presented in this paper for improving the reliability and power quality of the distributed system that the microgrid is connected to. In order to improve the system computational time and response a new control algorithm is designed for controlling the Facts device. Also, Fuzzy Controller is also employed in this paper for frequency tracking and for extracting the harmonic spectra of the grid voltages and load currents in a micro grid. The design concept is tested in different cases using Matlab/Simulink.
