Abstract

In this paper, an optimization problem is formulated for optimal allocation and sizing of harmonic
passive single-tuned lters in a power distribution system with the objective of minimizing its THD (Total
Harmonic Distortion). Voltage magnitude, tuned frequency, THD and power factor are treated as inequality
constraints with upper and lower bounds. The problem is solved via genetic algorithm which determines the lters
locations, their connection types and parameters values, including the tuned resonance frequency and quality
factor. An IEEE 33-bus radial system is used for demonstrating results obtained by the proposed method.
