Formulação do Problema de Fluxo de Potência Ótimo Através de um Modelo Implicitamente Acoplado

Abstract

In this work, the optimal power flow problem is formulated based on the implicitly coupled method (CRIC - Calcul de Reseaux Implicitement Couples) with the objective of optimizing energy generation costs and the voltage level of the electrical power system while satisfying the main operational and network security constraints. The characteristics and implementation processes used in the development of the implicitment coupling method are presented and discussed in detail. The proposed method was implemented in the AMPL language, solved using the solver KNITRO, and applied to IEEE 118-, ACTIVSg200-, and ACTIVSg500-bus systems. The obtained results demonstrate that, compared to the traditional coupled method, the proposed method for solving the optimal power flow problem determines solutions of comparable quality, if not superior. This presents the implicitly coupled method as a novel and promising alternative for the large-scale electrical system optimization.
