Analysis of the variation of the voltage magnitude and phase angle at both ends of small impedance branches is presented.This analysis is based on element equations of PQ decoupled load flow which has a good convergence for a system with small impedance branches.The analysis also demonstrates that the PQ decoupled load flow method may be used to develop fast,superior and robust algorithms.
