RESUMO

This work investigates methodologies to automatically obtain energy restoration plans in distribution systems, involving multiple objectives that are conflicting. The reduction energy interruption indices is a permanent objective of the distribution companies in order to improve power supply. Interruptions may be carried out for maintenance or may occur due to system faults. After a fault have been identified and isolated, a restoration plan is required in a short interval of time. Due to the combinatorial explosion problem it is not possible to apply mathematical programming techniques to produce restoration plans for large networks. On the other hand, an evolutionary algorithm utilizing graph, chain has shown to be able to obtain restoration plans for real-size networks in a short interval of time. Tests are performed for three different size networks, considering several objectives to evaluate the proposed technique.
