Abstract

Through the load flow in an electrical power system one can determine the state of the network, how the flows are distributed and other quantities such as voltage and current. The traditional methods of calculating the load flow, such as the Newton-Raphson and Gauss-Seidel methods, present performance and convergence problems due to the peculiar characteristics of the distribution systems,  thus it was necessary to adapt iterative methods, already used, in order to correct technical imperfections, making the characterization of the electrical power system as reliable as possible. This work aims to analyze an iterative method, used for load flow analysis in distribution systems, presented in 2017 by Kersting, called Loop Flow. In the presentation of the method, two balanced sources are considered to close the mesh, however in this work it was analyzed that the behavior of the method when using two unbalanced sources. For this situation the result was non-convergence, so the method was adapted so that the convergence result could be obtained.
