Abstract:
A power distribution system reconfiguration methodology considering the reliability and the power loss is developed in this paper. Probabilistic reliability models are used in order to evaluate the reliability at the load points. An algorithm for finding the minimal cut sets is utilized to find the minimal set of components appearing between the feeder and any particular load point. The optimal status of the switches in order to maximize the reliability and minimize the real power loss is found by a binary particle swarm optimization-based search algorithm. The effectiveness of the proposed methodology is demonstrated on a 33-bus and a 123-bus radial distribution system. Index Terms—Binary particle swarm optimization (BPSO), distribution system reconfiguration, minimal cut set, power loss, probabilistic reliability model.
I. INTRODUCTION
DUE TO the rapid increase in the demand for electricity, environmental constraints, and the competitive energy market scenario, the transmission and distribution systems are often being operated under heavily loaded conditions. In the earlier days, evaluation of the adequacy of the generation system and reliability of the transmission system were among major studies in the system planning. The recent experiences from blackouts indicate that, in many cases, the triggering events for such widespread failures took place in the distribution level [1]. Statistically, the majority of the service interruptions to the customers come from the distribution systems [2], [3]. Detailed reliability evaluation of the distribution system has, therefore, become very important in the planning and operating stage of a power system. For economic reasons, minimization of the losses in the distribution system should also be considered in a distribution system reconfiguration process.
