Análise de métodos de agrupamento de conjuntos de unidades consumidoras aplicados na definição de limites dos indicadores de continuidade

Abstract

In the context of electricity distribution in Brazil, the National Electric Energy Agency (ANEEL) is responsible for regulating and inspecting the performance of companies. The quality of services provided by distributors is measured by indicators of continuity of supply, to which performance limits are defined using a comparative analysis methodology. The premise of this methodology is that similar sets of consumer units must have equivalent performance. Such similarity between sets is defined by attributes, which describe characteristics of the electric distribution system and the consumer market. Failure to comply with regulatory limits implies the payment of financial compensation to consumers, which can represent a significant part of the company’s revenue. Thus, the methodology for calculating the limits can influence the financial results of distributors. This work analyzes the step of grouping sets of the current model used by ANEEL for calculating the limits of the DEC and FEC indicators. The limits for different case studies are calculated, in which the selected attributes, the grouping method and the adopted parameters are varied. Then, the sensitivity of variations is analyzed through the limits calculated in each case study. As main results, it was observed a greater sensitivity for variation of attributes and of the clustering method and a lower sensitivity for variation of the parameters of the dynamic method.
