ABSTRACT: The objective of this work is to analyze a load flow program based on Newton Raphson method and Fast Decoupled method. MATLAB software is used for this study. The program was run on an IEEE 30-bus system test network and the results were compared and validated for both the methods. Both the NewtonRaphson method and the fast decoupled load flow method gave similar results. However, the fast decoupled method converged faster than the Newton-Raphson method. The bus voltage magnitudes, angles of each bus along with power generated and consumed at each bus were evaluated. It is estimated that the total power generated is 192.06 MW whereas the total power consumed is189.2 MW. This indicates that there is very less line loss of about 2.86 MW. Moreover, the fast decoupled load flow method is verified to be more efficient and consistent method of obtaining optimum solution for a load flow problem
