Planejamento da geração distribuida com foco na confiabilidade

Abstract

The present work presents a methodology for the allocation of Distributed Generation units in the Electric Energy Distribution System aiming at the improvement of network reliability indicators. The objective is to evaluate the best point of the system to perform the insertion of the GD unit. An analysis of how this allocation affects the quality indicators and the electrical losses of the system under study is also carried out. The inclusion of a limit for a quality indicator considered in the distribution of electric energy is explored in this work, verifying that the insertion of distributed generation in the network can cause that such restriction is met. The proposed methodology is based on the metaheuristic techniques Artificial Immune System and Genetic Algorithm in order to compare the results obtained by both techniques. The objective function evaluated is composed of a sum of the costs of reliability, costs of investment in distributed generation and the costs of the electrical losses of the system; always seeking to minimize these costs. The proposed algorithms are tested in systems known in the literature.
