OPTIMIZATION OF PARAMETERS OF THE UNIFIED POWER QUALITY CONDITIONER USING GENETIC ALGORITHM METHOD

Abstract

This paper presents a novel technique of optimization of parameters of the UPQC using Genetic Algorithm (GA) method that takes curves of bode as a basis. The choice of the parameters of the shunt active filter is determined by the ratio of its generated current to the harmonic current, while the choice of the parameters of the series active filter is determined by the ratio of its generated voltage to the harmonic voltage. The total impedance of the whole system without load shows that a phenomenon of resonance could appear. To overcome the problem of reso-nance and widen the pass band, the Genetic Algorithm method was used. Simulation results are presented to validate the proposed method.
