Abstract :
This paper presents a study of passive harmonic filter planning in the power system. The purpose is to find the optimal locations for harmonic filters among existing capacitor buses in the power network, based on sensitivity analysis. The planning problem is formulated as an unconstrained optimization problem. The inductor size of each shunt filter is then determined while IEEE-519 recommended harmonic voltage and voltage distortion limits are maintained at each network bus. Simulation results obtained by testing a distribution system show that the proposed approach is robust, computationally efficient and suitable for siting and sizing passive harmonic filters.
