Validação de uma metodologia para restabelecimento de energia em cenários de múltiplas faltas em um sistema de distribuição real de grande porte

Abstract

The costly occurrences of faults in the distribution systems demand restoration plans that minimize the energy not supplied to consumers and respect the operational constraints of the network. In this context, this article seeks to computationally validate, in scenarios of multiple simultaneous faults, a methodology aimed at restoring energy in real distribution systems, capable of considering the existence of different levels of service priority among consumers, finding partial restoration solutions, in addition to prioritizing the operation of remotely controlled switches. Moreover, this article proposes an extension to the exhaustive search applied locally to obtain complete restoration solutions in cases of faults that affect neighboring feeders. The methodology was tested in situations of up to four simultaneous faults and proved capable of providing solutions for the most critical and challenging scenarios of multiple faults.
