Abstract: Power-flow or load-flow studies are very important in determining the overall operation of the existing system as well as for planning of future expansion following the constraints under steady state conditions. Load flow or power flow will give the systematic mathematical approach for obtaining the voltages at the buses, currents through branches and active and reactive power flow through different branches in the given system. In this paper, a new load flow method based on back tracking search algorithm, which in turn uses compensating factors. The system parameters are updated locally and as well as globally to obtain the solution without any iterative processes. The complete methodology is explained with supporting numerical and graphical results for Radial-33 node and Radial-69 node test systems.
Keywords: Distribution load flow, Back tracking search algorithm, Local compensating factor, Global compensating factor.
