A New Approach to Load Flow Solutions for Radial Distribution System

Abstract

This paper presents a new approach to load flow solutions for radial distribution system, in which the choice of the switches to be opened is based on the calculation of voltage at the buses, real and reactive power flowing through lines, real power losses and voltage deviation, using distribution load flow (DLF) program. In the process of load flow calculation, two developed matrices bus injection to bus current (BIBC) and branch current to bus voltage (BCBV), and a simple matrix multiplication are used to obtain load flow solutions. The solution converges very early on; therefore execution time is very small. Particular attention is paid to the relationship between electrical parameters of the distribution system and the mathematical parameters that influence the convergence properties of the algorithm. The results reveal the speed and the effectiveness of the proposed method for solving the problems
