Metodologia para priorização de investimentos em redes de distribuição de energia elétrica com foco em ganhos operacionais e financeiros

Abstract

The current scenario of the Brazilian electricity sector, through the constant and recent regulatory changes imposed by ANEEL in recent years, aims to ensure continuous improvement in quality standards in the provision of electricity, significantly increased surveillance on the power quality delivered to consumers. Following this guideline, ANEEL established X Factor, which set the minimum volume of investments required to electricity distribution companies. In 2010, through the PRORET ANEEL established a new methodology for the calculation of the X Factor, including the Q component, relating to quality of service, setting a milestone in the recent regulatory history of the Brazilian electricity sector, as it allows for the first time gains the annual tariff adjustment or loss according to the performance measured in the year. In this context of regulatory innovations and increasing demands with performance standards and levels of investment made on the electrical system, the correct and efficient use of increasingly scarce resources to improve and expand the electrical system are presented as a vital challenge to financial health of companies. This paper presents a methodology for prioritizing investments in primary networks of electricity distribution, involving two consolidated methodologies aid to decision-making high complexity (AHP and PROMETHEE) and operations research methods to optimize the planning of improvement works to be held in short-term horizon, with direct reflection on regulatory issues, seeking still accommodate regional characteristics of the company and the ability to execute works of each region.
