P.Sobha Rani , Dr. A. Lakshmi Devi

Distributed generators are beneficial in reducing the losses effectively compared to other methods of loss reduction. The challenge of identifying the optimal locations and sizes of distributed generation has great research interests nowadays. Many efforts have been made in this direction. In order to minimize line losses of distribution system it is important to define the size and location of DG to be placed. Wih optimal size of DG unit at a suitable location it resulted in reduction in power losses and improvement in voltage . This paper proposes a genetic algorithm based approach for optimal placement of multi distributed generation in a distribution system. The proposed algorithm is tested on IEEE 38 distribution system for locating and sizing of optimal DG source. The DG unit size is calculated by using exact loss formula. With the optimal size of DG unit at a suitable location, it resulted in reduction in real power loss,reactive power loss and improvement in voltage profile.
