This paper presents an effective methodto solve the reconfiguration problem of distribution systems for minimizing the real power losses using the new proposed technique and the ant colony optimization. The proposed technique based on three operations on loop removal, loop update and loop subscription is introduced to generate the feasible solutions and to correct the infeasible solutions during the whole evolutionary processwithout applying tedious mesh checks, therefore the computational burden and optimization time are reduced. The effectiveness of the suggested technique is demonstrated on 33-, 69-and 118-bus test distribution systems. The simulation results indicate that the proposed method is useful andefficient for the reconfiguration problem of distribution networks.
