Placement of DG in Distribution System for loss reduction

The development of Distribution Generation (DG) will bring new changes to traditional power systems. Appropriate size and location of Distributed Generation play a significant role in minimizing power losses in Distribution Systems. This paper presents an algorithm to obtain the optimum size and optimum location of the DG´s at any bus in the distribution network, including power cost and the available rating of DG´s if the DG´s exist in a competitive market. An algorithm is applied to 30 bus radial system using single as well as multi placement of DG´s in distribution system and its result indicate that, if the DG´s are located at their optimal locations and have optimal sizes, the total losses will be reduced in the distribution network. The results can be used as a look-up table, which can help design engineers when inserting DG´s into the distribution networks.
