FLUJO DE CARGAS NEWTON-RAPHSON CON INYECCION DE CORRIENTE BASADO EN MATRICES DISPERSAS

Abstract

El metodo del flujo de cargas Newton-Raphson es ampliamente utilizado en aplicaciones industriales. El principal inconveniente de este metodo es la factorizacion y la actualizacion de la matriz Jacobiana del sistema durante el proceso iterativo. Este articulo describe el flujo de cargas Newton-Raphson basado en los residuos de la inyeccion de corriente y el uso de la matriz dispersa. Se considera que el calculo de la matriz Jacobiana es la principal ventaja de este metodo de flujo de cargas, donde, los elementos no pertenecientes a la diagonal y algunos elementos diagonales son constantes e iguales a los elementos correspondientes de la matriz de admitancias. El metodo de residuos de la inyeccion de corriente se considera un metodo de flujo de carga robusto especialmente cuando las barras son de tipo PQ. La tecnica de matrices dispersas se aplica para el analisis de redes a gran escala para reducir el tamano de la memoria y el tiempo de calculo. La libreria SuperLU es utilizada para realizar todos los calculos de las matrices del sistema. Por lo tanto, la matriz Jacobiana se divide a cuatro matrices, donde, cada matriz tiene la misma estructura de la matriz de admitancias e incluye solo los elementos no nulos. El algoritmo propuesto ha sido comprobado usando los sistemas de transporte IEEE.
