Though the Newton-Raphson method usually converges to a solution of the simultaneous nonlinear load flow equations, it can occasionally be nonconvergent. In this paper a method for identifying weak areas of systems which prevent convergence of the Newton-Raphson method is presented. This information aids load flow program users in the modification or correction of system data to obtain convergences. The method is tested on a 28-note test power system and on an 84-node case from a utility company.
