Optimal capacitor placement and sizing in radial distribution system using accelerated particle swarm optimization

摘要

In this study, the problems are how to determine the locations and the size of capacitors in the buses of radial distribution system. The proposed method uses loss sensitivity factors (LSF) to identify the buses requiring compensation and then an accelerated particle swarm optimization (APSO) algorithm is used to determine the sizes of the capacitors to be installed. The proposed method is tested on 84 distribution systems. Absolutely, it is compared with PSO algorithm to find out the performance of convergence. By using proposed method, it could reach 99.79 second computational time. It showed that proposed method has good performance of convergence than PSO algorithm.
