HARMONIC MITIGATION BASED ON OPTIMAL ALLOCATION AND SIZING OF TUNED FILTERS USING GENETIC ALGORITHM

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