A growing number of harmonic mitigation techniques are now available including active and passive methods, and the selection of the best-suited technique for a particular case can be a complicated decision-making process. The performance of some of these techniques is largely dependent on system conditions, while others require extensive system analysis to prevent resonance problems and capacitor failure. A classification of the various available harmonic mitigation techniques is presented in this paper aimed at presenting a review of harmonic mitigation methods to researchers, designers, and engineers dealing with power distribution systems.

1. Introduction

The classical disruptions present in the distribution network and inside the industrial plants, the influx of digital computers and other types of electronic controls used by industries to achieve maximum productivity, the increase of the power based on renewable energy and the reduced redundancy in lines and substations, has a negative impact over the medium and low voltage distribution network power quality, as well as in the industrial customer installations.
