Optimal Placement and Sizing of Distributed Generation for Power Loss Reduction using Particle Swarm Optimization

摘要

This paper presents a new methodology using particle swarm optimization (PSO) for the placement of distributed generation (DG) in the radial distribution systems to reduce the power loss. Single DG placement is used to find the optimal DG location and its size which corresponding to the maximum loss reduction. The proposed method is tested on the 26-bus radial distribution system which modified irom the Provincial Electricity Authority (PEA) distribution system. The total power is 8.49 MW and 5.97 MVAR and the power loss is 11.68 kW and 26.08 kVAR. The load flow analysis on distribution use forward-backward sweep methodology. The simulation results show that PSO can obtain the maximum power loss reductions.
