Fault Indicators Allocation Using Variable Neighborhood Search Aiming Energy Quality Improvement Jáder de Alencar Vas-concelos, Antônio César Baleeiro Alves, Marcelo Escobar de Oliveira, Luis Gustavo Wesz da Silva 2018/04/20

Abstract

Distribution systems are affected by faults that may lead to service interruption, which is inconvenient for the con-sumers and increases the refund costs payed by the company. Op-timizing the allocation of fault indicators devices (FIs) is a prom-ising alternative to improve the energy quality. Using FIs reduce the team`s average displacement time to the fault(s) location, which implies reduction on the Equivalent Interruption Duration per Consumer Unit (DEC) indicator. Since the indiscriminate use of FIs is prohibitive, this paper presents the implementation of the metaheuristic routine Variable Neighborhood Search (VNS) to determinate optimized locations to install the FIs, aiming DEC reduction. The results, collected from a real feeder, confirm the proposed methodology`s efficiency.
