Ferramenta para maximização de carga na fase fluente de recomposição de sistemas elétricos

Abstract

This work proposes a methodology to help the studies related to electric power systems fluent restoration. At this early restoration stage, power system is structured in long transmission corridors and the reactors set definition is one of the adopted strategies for overvoltages disposal. The proposed tool, based on an optimization model, aims the network procedures establishment leading to a minimum reactors configuration connected to the system and maximum load pick-up during this restoration phase. The various fluent restoration scenarios, corresponding to new transmission lines sections inrush, are represented by sub problems. Benders decomposition technique associated to primal-dual interior points methodology is used to solve the proposed nonlinear optimization problem. Case studies are conducted in fluent restoration branches of Brazilian Electric interconnected System to verify the methodology effectiveness. The results are compared with other proposed methods in the literature.
