Abstract: The main aim of the paper is to reduce the costs of generation of power of DG as well as reduction in the supply intake from the substation with respect to reduction in the system real power losses and voltage profile improvement maintaining the stable limits of the system constraints using constriction and weighted factor coefficients of Particle swarm Optimization. As many researchers focused only loss reduction and some concentrated on voltage profile improvement and in this paper the loss reduction, voltage profile improvement as well as cost reduction of the operation of DG are taken as a single objective function within which highest priority given to cost reduction, next priority to loss reduction with voltage profile improvement. As a result we get the best cost effective optimal sizes of DG’s or DG and their respective placement such that costs reduced in operating DG with good voltage profile improvement and the proposed method is tested on IEEE 33 bus system at different power factors.
