Reconfiguración multiobjetivo en sistemas de distribución primaria de energía

Abstract

This paper presents the problem of power loss reduction in the distribution power systems without affecting the supplied electrical service quality. An approach of this problem using a methodology for the multi-objective reconfiguration is proposed. In the statement of the problem two objective functions are used: The Net Actual Value of Costs (VANC) and the Equivalent Duration of Interrupted Power (DEPI). While in the model’s solution a Non-dominated Sorting Genetic Algorithm (NSGA-II) is used, which is an evolutionary algorithm implemented in MATLAB from where a feasible set of solutions is obtained. The methodology proposed is used in the reconfiguration of circuits Y-410, Y-283 and Y-285 in the Camagüey city, Cuba, where the power losses were reduced in 51.7 kW, improving in that way the quality of the service supplied, diminishing to 0.3966 hours/year the equivalent hours in which the electric service fails for each kVA installed in the clients.
