Optimal size and location of Distributed Generation and KVAR support in unbalanced 3-Φ distribution system using PSO

This paper proposes a Particle Swarm Optimization based methodology for finding Optimal size and location of Distributed Generation and unbalanced Reactive power support for unbalanced three phase distribution network. The improvement in voltage profile and loss saving are presented. The proposed technique is tested on IEEE 37 node radial test feeder which is an actual feeder in California. The program is developed using MATLAB programming software. The results obtained show the effectiveness of the method for unbalanced network.
