Abstract

This study presents a methodology using Particle Swarm Optimization (PSO) for the placement of single Distributed Generation (DG) in the radial distribution systems to reduce the power loss. The single DG placement is used to find the optimal DG location and sizing which is corresponded to the maximum power loss reduction. The proposed method is tested on the 26-bus radial power distribution system which modified from the Provincial Electricity Authority system in Thailand. The load flow analysis on distribution system used forward-backward sweep methodology. The simulation results show that PSO can obtain the maximum power loss reductions. The total consumption power is 8.49 MW and 5.97 MVAR and total power loss is 11.68 kW and 26.08 kVAR. This study can be verify that the PSO method can solve the best placement and sizing on the real system.
