A new combinational objective function for locating switches in distribution network

Distribution networks are often very wide and are comprised of vast number of feeders. Always feeders are considerably broadened, and for them lots of maneuver points placements are predicted for load relocation and reducing the power outage period of customers. In this paper, locating the switching equipment in a radial distribution feeder is investigated. Given to budget restrictions and looking for technical and economic considerations and importance of load points, a combinatorial objective function is defined that pursues three main goals. First goal is minimizing installation and maintenance costs and power outages by optimal switches placement so that maximum budget is considered. For the second goal, consuming available and financial resources in distribution network is investigated in order to optimizing reliability. As the third goal, reaching a particular reliability level with the lowest price is considered. For optimization problem single objective and double objective genetic algorithm are employed. Experiments on a paradigm network and on a real Iranian power distribution network has validate the efficiency of the proposed method.
