Abstract: Service restoration in power distribution system is to restore power in healthy portion of out of service area as much as possible followed by a fault and isolating the faulted zone by operating the line switches connected in the network. In service restoration, not only the final network configuration but also the number of switching operations held for service restoration is important with a number of constraints like node voltage deviation, load balancing and priority customers. Thus the Service restoration problem is a multi objective multi constraint (M.O.M.C) combinatorial optimization problem. This paper proposes an Ant Colony optimization based methodology for minimizing the area where energy is not supplied and no of manually controlled and remotely controlled switching operations during the restoration process. A fuzzy membership function is defined for each term in objective according to relevant conditions and the final solutions are ranked according to the importance of objective under consideration.
