This paper proposes the optimal designs of passive power filter (PPF) using the advanced particle swarm optimization (PSO) method. In the PPF optimal design, the purposes are to minimize the total harmonic distortion (THD) and original investment cost, while maximize fundamental reactive power compensation. Several constraints of THD, individual harmonics, fundamental reactive power compensation, and parallel and series resonance with systems are considered comprehensively. Furthermore, the detuning effect is considered as a constraint during the optimal process, which improves the reliability and practicability of design results. And a novel optimal strategy is proposed in this paper to solve the multiobjectvie optimization problems for PPF, which can make a compromise among all the objectives. Finally, the optimal design results are compared with those designed by the conventional method, which shows the superiority and availability of the proposed design methods based on PSO.
