Optimización multiobjetivo de la red de distribución de energía eléctrica

Abstract

The optimal design of the electric power distribution grids has been developed through the application and adaptation of the evolutive algorithm NSGAII. This algorithm is based on the elitism and dominance of Pareto. To this end, three objectives have been considered: the maximization of loses; the maximization of the reliability of the system supply and a costs function. This costs function is not the generic one of costs minimization, but a new function adapted to the sector reality, and so it is considered as a function of maximization of the retribution of the retribution activity. The problem is supedited to the habitual restrictions of voltage drop, capability of the elements, radiality of the gris and power balance. There are also two specific restrictions related to the legiation: the standarization of the elements and the maximum investment allowed.The location and size of the lines and substations that must be installed or enlarged are considered decision variables.
