This paper proposes an efficient methodology for distribution network loss minimization and voltage stability improvement with optimal Distributed Generation (DG) placement and operation. A sensitivity-based technique is developed for finding the best location for DGs. Subsequently, with an objective to minimize the network power losses and improve its voltage profile, optimal size and power factor for the DGs are obtained by solving non-linear Optimal Power Flows (OPFs). When applied to standard distribution test systems such as IEEE 69 bus and Indian 85 bus networks, the proposed technique shows its effectiveness with significant reduction in network losses for all test cases. Use of free and open source software for the development and application of the methodology provide a cost-effective solution to the utilities.
