ABSTRACT: Feeder reconfiguration for minimum power losses and power quality improvement considering different distribution generations (DGs) based on fireworks algorithm (FWA) is presented in this paper. Various DGs are classified into PV, PI and PQ(V) types. Power flow based on BIBC (bus injection to branch current) and BCBV (branch current to bus voltage) matrix is employed for distribution power system. And voltage stability index (SI) is developed to evaluate the performance of the feasible topology. FWA is proposed to optimize the combination of switches in distribution power system which is a new swarm intelligence optimization algorithm using the fireworks explosion process of searching for the best location of sparks. The method had been tested on IEEE 33-bus and IEEE 69-bus radial distribution systems with DGs and without DGs. The result shows the effectiveness and robustness of the proposed method by comparing with binary particle swarm optimization algorithm (BPSO).
