Abstract

The improvement of power quality (PQ) is the main aim of this paper. Here, the enhancement of PQ through harmonic filters (HFs) is simulated on the IEEE-69 bus radial distribution system (RDS) with nonlinear distributed generation (NLDG). The aim of minimizing harmonic distortion within standard limits is achieved using proper placement of HFs and an optimization algorithm. The optimization problem in this study is characterized by nonlinear constraints. The placement of HFs is accomplished using a newly published method. It is a nonlinear load position-based current injection (NLPCI). To determine an appropriate rating of HFs for reducing total harmonic distortion of voltage (THDv) and meeting the standards set by the IEEE, a novel bat algorithm (NBA) is employed. The NBA is compared with the Bat Algorithm (BA), Particle Swarm Optimization (PSO), Gray Wolf optimization (GWO) and the Firefly Algorithm (FA) in terms of efficacy. The comparative analysis of results shows that in terms of computational efficiency, the NBA performs better than the BA, PSO, GWO and FA.

Keywords: Active Power Filter, Harmonics, Power Quality, Power System Optimization, Radial Distribution System, Soft Computing.
