This paper presents a study on the convergence characteristics of the backw
ard/forward sweep method, which is one of the most effective methods for th
e load-flow analysis of the radial distribution systems. After revisiting t
he theoretical background, the convergence conditions and the evolution of
the iterative process are investigated in detail for different load models.
A dedicated study of the properties of the backward/forward sweep method i
s performed, taking into account different line X/R ratios and different ty
pes of voltage-dependent loads. Some useful indicators are introduced to es
timate the number of iterations required to reach the convergence of the it
erative process under a given tolerance. Test results are included for a tu
torial two-node system and for a real 84-node system. (C) 2000 Elsevier Sci
