Abstract—This paper proposes a new reconfiguration heuristicin order to reduce the total power loss and the maximum currentof electrical radial networks. It is based on the branch-and-boundstrategy, which is an implicit enumeration method that uses a treestructure and bounds to organize the searching process. The searchtree in this paper is constructed by subdividing the feasible setusing the branch-exchange technique in the networks. The constraints and the Pareto dominance are responsible for pruning thesearch tree. The heuristic also returns a feasible switching plan foreach solution. The algorithm was successfully applied to mediumand large-scale problems.Index Terms—Electrical energy distribution, heuristic method,multiobjective reconfiguration, radial network.
