Power flow analysis of unbalanced multiphase radial distribution systems

Abstract An alternative algorithm for power flow solution in radial distribution systems is presented. The algorithm uses a quartic equation of bus voltage magnitudes at the ends of a distribution section in a forward bus trace sequence, and the total power flows are summed up in a reverse component trace. A versatile implementation of the algorithm for the analysis of multiphase unbalanced distribution systems is described. Results of example problems solved using the algorithm are presented. A comparison of some of the special features of the algorithm with other methods reported in the literature is included.
