Estudo do máximo carregamento em sistemas de energia elétrica via método da barreira modificada

Abstract

In this work the Modified Barrier Lagrangian Function (MBLF) method, a variant of the Interior Point Method, is applied for determination of the maximum loadability point in power systems. The formulation of the problem will have as constraints of equality the power system swinging equations, in a parametrized form, and as inequality constraints the voltage limits in the buses and the reactive generation limits in the buses with reactive control. The results found with the static optimization technique used in this study are confronted with the results obtained with the Primal-dual Barrier Logarithmic method. The performance of the method is illustrated using as pattern the systems IEEE 14, 57 and 118 bars. The tests demonstrated the robustness and the efficiency of the proposed algorithm.
