The regulation in the public electric energy distribution service considers quality and continuity indicators, presented in Module 8 of the Electric Energy Distribution Procedures in the National Electric System (PRODIST), established by the National Electric Energy Agency (ANEEL). Collective continuity indicators are defined for measuring the distribution quality services, such as: System Average Interruption Duration Index (SAIDI) and System Average Interruption Frequency Index (SAIFI). Also, there are several individual indicators of continuity that deal with the single consumer unit interruption, such as: duration (CAIDI) and frequency (CAIFI). Each of these individual indicators has a stablished limit value, which, if exceeded, results in financial compensation by the utility directly to the consumer units. In this way, this paper presents a methodology applied in an algorithm developed with the purpose of analyzing these indicators impacts along with their financial compensation for modified configuration of the current sets of consumer units of an energy utility, based on the contiguity criteria. For the development and application of the methodology, initially each substation is considered as a unit of consumers combined. Real consumer history data were used, from 2017 to 2020, with the study area consisting of four sets and five substations, where 43 configurations are proposed, divided into 5 scenarios. The new proposed configurations resulted in a reduction of 1.80% in the total amount of financial compensation, referring to the indicators CAIDI and CAIFI, monthly period. In addition to a 45% reduction in the SAIDI and 26% in the SAIFI, for the four years under study. Meaning there is a possibility of future gains by carrying out a reconfiguration of sets without the requiring investment in the grid system.
