Otimização de redes de distribuição através da inserção de chaves e da redução de perdas elétricas: um estudo de caso

Abstract

Electric distribution networks are essential within the electric power system, since they are responsible for the delivery of electricity to the consumers. The malfunction of these networks causes harm to the consumers, either by lack of energy or by the low quality of the delivered power. The proposal of this work is to study a distribution network with seasonality load characteristics in order to find the most significant variables and to optimize the operation to reduce power losses and to improve the network continuity, without major investment. For such end, methodologies have been proposed for the reconfiguration of the network and for the analysis of continuity in supply, after the determination of problematic sections of the system. Thus, they were indicated the portions of the system where investments should be made, improving their performance. The study was based on a real distribution network, from which the possible solutions were simulated for each situation investigated.
