Reconfiguration of distribution networks by a series of switching operations is a simple and inexpensive way to improve reliability and reduce power losses, which without the addition of additional equipment to the network, makes optimal use of distribution systems. In this paper, optimal reconfiguration is proposed to improve reliability and minimize power losses as objective functions. To demonstrate the functionality and applicability of the proposed method, five states are defined based on the trade-off between buyer-seller. Particle swarm optimization (PSO) algorithm has been used to solve this problem. Then, the proposed method has been implemented on the Lorestan Distribution Network.
