Abstract

AbstractRecently, to enhance the power system performance, integration of DGs at distribution level and the rearrangement of feeders in distribution network is done. This paper presents a harmony search algorithm approach for the reconfiguration of radial distribution system with distributed generation (DG). The DG placement problem and reconfiguration problem is formulated as a non-linear optimization problem with the objective of loss minimization and voltage profile improvement. Particle swarm optimization (PSO) algorithm is used to find the optimal location and sizing of multiple DGs. To find the optimal set of feeders to be opened, harmony search algorithm (HSA) is proposed. The proposed approaches are tested on IEEE 33 bus radial distribution system using MATLAB and the results are presented.KeywordsDGReconfigurationPSOHSA
