A Stochastic Optimization Method Applied for Single Tuned Passive Filter Planning

Power system harmonics is one of the power quality problems. This study proposed an optimal single-tuned filter to eliminate harmonics in the power system using an optimization tool known as Mixed Integer Distributed Ant Colony Optimization. Two objective functions have been considered: the total of harmonic voltage distortions and transmission losses. The global maximum and minimum were achieved by maintaining the desired range of power factor, the quality factor is maintained within a specific range, avoiding harmonic resonance, and ensuring that capacitors and harmonic voltage do not violate IEEE standards. On a comprehensive passive filter design, this study also presents the advantages of multi-objective approaches over single-objective optimization using the proposed technique.
