Distribution networks are responsible for supplying electricity to most consumers, and also are the power system part where the majority of electricity interruptions occurs. These infrastructures are in urban and rural regions and are organized to meet different geographical and operational restrictions and the energy demand. In this study, the use of metrics from complex networks theory to describe the organization of such important systems in topological and electrical perspectives was evaluated. A variety of metrics were extracted from different distribution networks. They were calculated considering topological and active power flow in nominal conditions information. The values obtained were investigated using exploratory factor analysis approach. Results indicated that the metrics can be grouped into three distinct factors, and there is a metric, unrelated to such factors, which describes how the power flow is distributed over the network structure. Considering the importance of such systems and the various possibilities of the operational and topological organization, the knowledge of metrics capable of characterizing, in a systemic perspective, is significant for the analysis of current and future challenges related to energy distribution. This topic and its applications will be furtherexplored in future research.
Nesse trabalho é abordado o problema de restabelecimento de sistemas de distribuição de energia elétrica (RSDEE). Uma introdução do problema é apresentada juntamente com uma breve discussão sobre estrategias para tratar o problema. A utilização de um algoritmo genético hibrido com busca local é proposta visando encontrar boas soluções em pouco tempo. Experimentos são realizados com as redes IEEE 14 bus test case e case 30 do MATPOWER, indicando que a abordagem híbrida resulta em melhor performance quando comparada a uma abordagem sem a busca local.
