Acceleration Factor Optimization of Gauss-Seidel Numerical Analysis for Power Flow Using FA

Abstract Load flow analysis is one of the essential ways used by electrical power engineers to achieve high system quality owing relevance load in economic optimization, planning, and stability. This issue can be formulated as a set nonlinear algebraic equations, which solved iterative algorithms. Gauss-Seidel simple determining system, with acceleration factor being most considerable modification when aiming at improving accuracy this method. article reports determination optimal using PSO Firefly (FA) The simulation was done MATLAB 4-bus, 6-bus, 9-bus IEEE standard for factor. proposed methods were evaluated benchmarked against conventional value number iterations fitness function. outcome study showed FA method preferable identifying optimum
