Reconfiguração de redes de distribuição de energia elétrica usando algoritmo genético multiobjetivo

Abstract

In this work, the reconfiguration of electrical energy distribution systems is studied by using a multi-objective genectic algorithm. Three objective functions are considered here: monetary costs of the network(installation, maintenance and energy losses), costs involved in the reability of the system and number of lines switching used for the reconfiguration. The multiobjective algorithm used here is the NSGA II. Faults in the system branchs and changes in the loads at the buses have been simulated to provoke a system reconfiguration. Two test systems have been used: A 21 bus system and an 100 bus system. A novelty presented here is a methodology based on optimization for choosing the spare cables of the network.
