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 further explored in future research.
