Optimal configuration of power quality compensation devices in microgrid

In view of the economic and technical optimization objectives for the power quality of microgrids, this paper presents a mult i- objective optimization configuration model for passive power filters (PPF) and active power filters (APF). A linear weighted method is used to handle the multi-objective optimization problem, and an improved particle swarm optimization algorithm is proposed for solving it. Taking into account the coordination between PPF and APF, the installation positions, capacities, and parameters of PPF and APF are optimized. Case studies show that the proposed model achieves the optimal configuration of power quality compensation devices for microgrids, with the objectives of minimizing harmonic content and maximizing investment economy.
