Performance improvement of Electric Power Distribution System Using DG

Distributed generation (DG) is a rapidly growing technology, which helps in proper planning for expansion of the electrical networks in order to face the load growth and to supply the consumers properly. In this article, computationally efficient & numerically robust distribution flow equations for the power flow solution of distribution system with distributed generation is presented. The effects of distributed generation on the system voltage profile and losses have been analyzed by using different sizes and locations of DG. The results show that the voltage profile is improved and losses are reduced, when a DG of proper size is incorporated at proper location in the system. The methodology is applied to IEEE-13 node test feeder system. © Association of Energy Engineers (AEE).
