Load flow analysis is an important aspect of power system studies in both planning and operating areas. This thesis studies several methods for load flow solution by developing corresponding digital computer programs and b applying them to different size systems. The conclusion was reached that the overrelaxed Newton-Raphson Method and the Optimum Accelerated Gauss-Seidel Method are the preferable methods for normal load flow studios. The speed of convergence and the optimum acceleration factor for different methods was studied using numerical analysis techniques. The relationship between tho optimum acceleration factor and the maximum eigenvalue of the coefficient matrix for each different method was determined and applied to the iterative process.
