Abstract
Since nearly about last three decades, there seems to be trend towards deregulation and restructuring of electricity supply industry all over the world. This has resulted in unbundling of generation, transmission and distribution network. The aim behind restructuring was to increase efficiency and to minimize cost of electricity supply to customers in the deregulated environment while maintaining a desired degree of reliability and quality of power supply. The major challenge before the electric utilities nowadays is to provide electricity of good quality due to advent of power quality sensitive equipments. Also to bridge the continually increasing gap between demand and supply of electricity, researchers had no option except to invent new sources and technologies of power generation. Distributed Generation (DG) which is a small scale electric power generation technology using different type of conventional & non-conventional energy sources that provide electric power at or near the load site is an example. It may be connected to the grid, directly to the consumer or both. DG is found to be a promising source of electricity generation that can completely fulfill the requirement of electricity as and when required around the globe. The Distributed Generation also found to relieve the transmission network indirectly as FACTS devices, detailed ahead. Number of benefits have been found of the insertion of Distributed Generation in the distribution network. But at the same time number of problems also arises in the distribution network by the insertion of Distributed Generation. This paper describes in detail the benefits and problems associated with Distributed Generation placement in distribution network. Few heuristic rules are proposed for sizing and siting of Distributed Generators in distribution network.
