Abstract— Optimal siting and sizing of Distributed Generation (DG) and other power compensating devices in distribution networks are the two crucial and also very important factors to get maximum benefits such as technical, economical, and environmental both for the utility and customers, especially, in sites where the central generation is impracticable or where there are deficiencies in the transmission system. This paper discusses an overview on different DG technology, available capacity and their merits and demerits. The state-of-art-of literature on operational (network reconfiguration in the presence of DG) and planning (optimal sizing and siting of DG, distribution system expansion planning with DG, and the DG-Capacitor placement) aspects in the presence of DG on the distribution networks has also been reviewed and presented. The various optimization techniques employed in the DG planning and operation with their merits and demerits has been discussed. Keywords— Distributed Generation, DG Technology, Distribution System Planning, Optimization Techniques.
