Description
Summary:Present scenario of Power system operation is contingency-constrained, and often associated with voltage limit violation problems. In this paper, the low voltage problems in an existing 2.2 MVA conventional electricity distribution network of a particular area of Gujarat State, India, have been identified and solved by injecting Renewable Distributed Generation at appropriate locations. The results of the simulations carried out using distribution system software were analyzed with respect to voltage at different nodes thereby identifying low voltage areas which were again studied by injecting RDGs at different locations and the results were analyzed. The final analysis revealed that there was no low voltage problem at any node on the network. It has been concluded that looking to serious environmental problems like pollution, greenhouse gas emissions, and long and over loaded lines attached to conventional electric power generation, transmission and distribution Networks, the injection of Renewable Distributed Generation can give a solution to low voltage problems. Reduction in losses and increased reserve capacity of the distribution network are the added advantages.
