Abstract

In this paper, results related to the statistical sensitivity analysis of physical-electrical attributes in reliability index calculation of distribution systems will be presented. Considering that electricity companies are inserted in a natural monopoly, the National Agency of Electrical Energy (ANEEL) current methodology proposes a comparative assessment strategy of different sets of consumer units, to classify their performance in relation to the power quality service. From a Stepwise regression model, the statistical sensitivity of different arrays of physical-electrical attributes is assessed. The results obtained for a real case studies demonstrate the impact of regional characteristics on the performance of distribution systems.
