In terms of technological advancement, DGs take part in minimizing power losses in the distribution system so as to achieve load requirements. An increase in power production has been capable of meeting growing demands at loading stations for the distribution system. One way to meet the essential load demand is to decrease the overall losses in distribution system. By lowering the reactive power losses of the system, actual power can be increased over the network. Therefore, in the distribution system by optimally allocating the DGs in distribution system we can decrease the power losses. The aim of the paper is to decide the best possible site and size of DG units to curtail the total reactive power losses & thereby reducing real power losses while keeping better voltages in distribution network. This paper work suggested an analytical method and also a new constant that identify the best optimally rating & site of DG. An objective function is presented to find the reactive power loss when fortified with DGs. The technique is experienced on standard 33 bus systems. On the basis of total reactive power loss minimization with real power loss minimization results are compared. The obtained results demonstrate that RPL reduction in RDS is feasible as compared to others.
