Novel Control Method on Unified Power Quality Conditioner (UPQC) for Harmonic Distribution Using PSO-Fuzzy Logic

Abstract

In this paper novel control method on unified power quality improvement for harmonic distribution using PSO-Fuzzy logic is implemented. There are various types of compensators such as parallel power quality compensator and series power quality compensatorwhichimproves the power quality. In this proposed work, control algorithm is developed on unified power quality conditioner. The entire algorithm is divided into three stages, in stage -1 all the parameters will be initialized and in stage-2 process computing the upper and lower boundary’s of X and Y is done. At last in stage-3 the process of commuting value of z is done and output is obtained. The simulation results show that fuzzy controller based particle swarm optimization will improve the accuracy, effectiveness and superiority.
