Análise do impacto de parâmetros regulatórios e de mercado no planejamento da expansão de sistemas de distribuição com geração distribuída

Abstract

The introduction of distributed generation (DG) in distribution systems should cause a paradigm change on the expansion planning. Few authors have been concerned about evaluating the long term impact caused by these local power sources in the distribution networks. Therefore, this paper proposes the extension of an expansion planning model for distribution systems, to include the DG problem in different regulation scenarios. The model is used to analyze the DG insertion impact in the expansion planning, as well as the impact of the regulation and market parameters associated to it. It was verified through simulation and analysis that, under the conditions established during the study, the DG may bring planning benefits, reducing the overall network expansion cost. Nevertheless, the regulation scenario and the market conditions might have a great impact on the benefits due to the DG presence.
