Hybrid methodology for optimal allocation of synchronous generator-based DG

Abstract

In this paper, a hybrid methodology is implemented for optimal allocation of synchronous generator-based dispersed generation, for minimization of power losses in distribution system considering voltage dependent practical loads. The proposed hybrid approach is a combination of equivalent current injection-based sensitivity factor and particle swarm optimization. Sensitivity factors advantages in reducing the search space and optimal allocation of synchronous generator-based DG are obtained by particle swarm optimization for the diminution of power losses. The suggested method is validated on 33-bus and 69-bus radial distribution system. The results show significant improvement in voltage profile of all buses after optimal allocation of DG in distribution system.
