Adequação do método da soma das potências versão retangular considerando elementos shunts de barra e de ramos de redes de distribuição

Abstract

Electrical distribution networks are mostly composed of series elements, which justifies the use of classical power flow algorithms based on this topology, such as the Power Summation Method (PSM) in its polar and rectangular versions. However, the inclusion of shunt elements—such as voltage regulators, capacitor banks, reactors, and the capacitive effects of feeders—requires adaptations to traditional methods. While the formulation of the PSM in polar coordinates with shunt elements is already discussed in the literature, there is still a lack of equivalent development for the PSM in rectangular coordinates. This work aims to propose a formulation that incorporates these elements into the rectangular PSM. The necessary equations are developed, followed by computational tests to evaluate the accuracy and performance of the proposed method compared to existing approaches. The results indicate that the new formulation preserves the reliability of classical methods while extending their applicability to more complex network configurations.
