Power flow analysis of balanced radial distribution system with composite load model

Abstract

In this paper, power flow solution of a balanced distribution system is obtained by formulation and multiplication of two matrices BIBC (branch current and bus current) and BCBV (branch current and bus voltage). The load is modeled as composite load considering all four practical voltage dependent load models. The projected method has been evaluated to demonstrate the convergence ability of the power flow program for different voltage dependent load models by varying loading conditions, power factor, R/X ratios and load growth scenarios. The method is validated by testing it on two systems: IEEE 30- and IEEE 33-bus system and the results are compared with seven existing methods in the literature.
