Aplicación de un Método Iterativo de dos Pasos para el Cálculo de Flujos de Potencia

Abstract

This paper presents an iterative method for solving the power flow equations, starting from the establishment of non-linear functions on each node. With the proposed method, N-1 nonlinear functions are generated, which are iteratively solved to achieve convergence at voltages of each node in the power system. The convergence analysis showed that the two-step iterative method is fourth order. The original formula of Newton-Raphson method in the first step and Halley-type method in the second step is used in this work. Test systems with 14, 30 and 57 nodes are simulated to determine the characteristics of the proposed method. Among the strengths of the method it may be mentioned that it does not require sophisticated programming and that it represents an additional method for calculating power flows.
