Abstract


A power system's most important and fundamental tool is load flow analysis. Most commercial power systems are too complicated to solve manually. Likewise, because of the power stream condition which is nonlinear, more calculation time were required and become confounded as the quantity of transport expansion in transport frameworks. Power flow solution iterative methods simulation can be used to improvise this. Using the ETAP (Electrical Transient Analyzer Program) software, a simulated iterative algorithm for resolving power flow equations was created. The study's objectives are to discover the distribution network's load flow solution, or system losses; to compare the time elapsed, real power losses, power mismatch, reactive power losses and load flow analysis using Newton Raphson, Gauss-Seidel, and Fast Decoupled method. The Port Harcourt zone 4 distribution network was tested by three different methods based on the results from the three, Fast Decoupled method required less number of iterations compared to Newton Raphson and Gauss-Seidels methods. All three iterative algorithms were successful to give the load flow solution for the Distribution system.
