7. ELECTRIC DISTRIBUTION POWER SYSTEMS RELIABILITY OPTIMIZATION: An Approach Considering the Selection and Allocation of Protection and Switching Devices / OTIMIZAÇÃO DA CONFIABILIDADE DE SISTEMAS DE DISTRIBUIÇÃO DE ENERGIA ELÉTRICA: Uma Abordagem Considerando a Seleção e Alocação de Dispositivos de Proteção e Manobras
One of the main goals of the electric utilities is to provide energy to its customers in a reliable and low cost way. Traditionally, the electricity sector regulatory commissions impose continuity targets, which must be carried out, to avoid great penalties. For many years, the electric utilities have adopted the practice of allowing the increment of tempora
