Distributed generation deployment: State-of-the-art of distribution system planning in sustainable era

One of the major consequences of evolutionary growth of industrial era is the continuously growing rate of energy consumption across the world. In the industrialized countries, the concern about economies accompanied by the environmental perspective is a significant driver for inventions of efficient and cost effective modular energy delivering structures. DGs with their heterogeneous forms are likely to be increased in utilization as an outstanding alternative solution to the prevailing energy crises. The advent of DG penetration is leading to fundamental changes in distribution network exploitation and exploration. Nonetheless the DG installation and exploitation has been debated in distribution networks, the fact is that, practically the Distribution Network Operators (DNOs) has limited control or influence over DG allocation and design. Their owners and investors depending on site and fuel availability finalize DG placement. The prime objective to achieve the most from DG installation, owes special attention of DNOs towards DG placement and sizing. This objective encompasses two major sub problems: which may be the optimal location for DG installation and with which capacity? Enormous quality literature is available enlightening this area. This paper presents a state of art of DG deployment techniques and their influence on the ongoing research efforts in this field. To relieve the imminent researchers from the difficulties of availing appropriate guidance, an elfin attempt has put forward through this paper by presenting significant information of research work done in this field.
