Alocação ótima de unidades geradoras em sistemas de distribuição utilizando programação evolucionária.

Abstract

The use of generators in actual distribution electrical systems is increasing mainly due to the government incentives to the use of new power sources in the energetical matrix of many countries. This increasing participation motivates the development of methods which allow technical and economical evaluation of such kind of investment in distribution networks. Thus, it is presented an algorithm for the allocation and sizing of generators in radial distribution networks in order to maximize the reduction on the total load supply costs. Additionally, it is given the operational schedule for each generator installed, in all load levels of the feeder. The evolutionary programming is used as the optimization technique. The applicability of the method was evaluated using a feeder with high losses index and the proposed generators allocation provided a considerable reduction on total costs.
