The network reconfiguration (NR) of a distribution system is a technique that well adapts to this new deregulated environment for it allows improvement of system reliability indices without the onus involved in procuring new equipment. This paper presents a reliability-based NR methodology that uses metaheuristic techniques to search for the optimal network configuration. Three metaheuristics, i.e. Tabu Search, Evolution Strategy, and Differential Evolution, are tested using a Brazilian distribution network and the results are discussed. © 2009 IEEE.engDifferential evolutionDistribution system reliabilityDistribution systemsEvolution strategyNetwork reconfigurationTabu searchCompetitive environmentDeregulated environmentsDifferential EvolutionDistribution networkEvolution strategiesMeta heuristicsMeta-heuristic techniquesNetwork re-configurationOptimal network configurationPower distribution companyReliability IndexReliability measureSystem reliability indexDistributed parameter networksEvolutionary algorithmsIntelligent systemsLocal area networksPumpsReliabilityTrabalho apresentado em evento10.1109/ISAP.2009.5352859Acesso aberto2-s2.0-76549109235
