An optimal strategy for switching devices allocation in radial distribution network

Métodos de programação inteira aplicados ao planejamento da automação de sistemas de manobra em redes de distribuição

“…As chaves automatizadas são equipamentos de custo elevado, entre U$ 9.000,00 e e 20.000,00 (CHAO-SHUN et al, 2006;DE TUGLIE et al, 2004), e que demandam um sistema de comunicação e software de gerenciamento. Devido a esse alto custo, nãoé viável, em um primeiro momento, a sua alocação generalizada em todos os alimentadores de uma rede de distribuição abrangente.…”

Anomaly Inference Based on Heterogeneous Data Sources in an Electrical Distribution System

“…The strategy of distribution system switch reconfiguration is utilized for fault localization, isolation, system restoration, and optimizing the performance during those procedures. In [141,142], the authors deal with the problem of optimal reconfiguration of radial distribution networks for minimum loss operations while [143,144] proposed an optimal strategy for switching devices considers costs of customer outage, installation, as well as annual operation and maintenance. A switch reconfiguration procedure was presented in [145,146,147,148] for distribution system restoration with maximizing the restored load and minimizing the number of switching operations and the analyses in [145,146] were based on graph theory.…”

“…The main purpose to exploit this problem is to achieve optimization. In [141,142], the authors deal with the problem existed in radial distribution networks for minimum loss operations while [143,144] proposed a strategy for switching devices considers costs of customer outage, installation, as well as annual operation and maintenance. In [145,146,147,148] introduce methods with maximizing the restored load and minimizing the number of switching operations to achieve distribution system restoration based on the graph theory.…”
