This research paper presents a comprehensive comparative analysis of load flow methods applied to the IEEE 39 bus system, focusing on Newton-Raphson, Gauss-Seidel, and two variations of the Fast Decoupled method, XB and BX. The study evaluates the convergence behavior and iteration performance of these methods across two widely used software platforms: MATLAB and Power World Simulator. Through extensive simulations, the research investigates the convergence characteristics and computational efficiency of each method, providing insights into their respective advantages and limitations. The findings offer valuable guidance for power system engineers and researchers in selecting suitable load flow methods for analyzing complex power systems.
