Description
Summary:Reliability is a fundamental concept for Power Systems and the application of efficient Switch Placement is a valuable tool for improvements. The goal of this paper is to present an approach for efficient switch placement in Power Distribution Systems using Pareto optimality of a multi-objective function to improve reliability of distribution power systems based on an index that is reasoned on the number of consumers unsupplied. The discrete Pareto front considers the trade-off between the number of switches and the number of deenergized customers. The cost-reliability dilemma solution uses a Particle Swarm Optimization algorithm to achieve a set of solutions assumed to be effective. Then, this set of solutions is subjected to a contingency evaluation in order to select the solutions that enable unconstrained system restoration within its limits of current and voltage. The approach is applied to the medium voltage distribution network of Ceara's Federal University campus. The approach is an important tool to support the planning of power distribution system.
