Formulação por balanço de correntes de barra para a solução do problema do fluxo de carga de redes de distribuição

Abstract

The classic formulation of the Load Flow Problem is based on calculating the power balance of buses in the electrical system under study and relies on obtaining the roots of residual power equations, whose solution needs to be obtained by iterative methods due to the non-linear nature of the equations. This Final Course Project aims to develop an alternative formulation for solving the Load Flow Problem of distribution networks, based on calculating the bus current balance and its solution by the Newton-Raphson Method based on obtaining the roots of residual current equations. The number of iterations and processing times are adopted as computational performance criteria for evaluating the developed formulation and comparing it with the classic Newton-Raphson method by power balance and the Sum of Currents, Sum of Powers, and Direct Load Flow methods. Distribution networks known from the literature are employed as test systems for evaluating and comparing performance based on normal operation and the limiting situation of system stability loss.
