Optimal Switched Dynamic Modulated Power Filter Compensator for Radial Distribution System

This paper presents a novel pulse width switched modulated power filter compensator (MPFC) for the voltage stability enhancement, energy utilization, loss reduction, and power factor correction in a radial distribution network using the Particle Swarm Optimization (PSO) technique. The MPFC is controlled by a novel dynamic tri-loop error driven controller. The dynamic controller is regulated to minimize the switching current transients, maximize power/energy utilization and to enhance power factor under normal and unbalanced load conditions. Particle Swarm Optimization PSO technique is used to find the optimal control settings that minimizes the distribution feeder current for feeder losses, voltage deviation at key distribution system buses, and Ensure feeder capacity release.
