Abstract Wu elimination method is applied to solve the analytical solutions of power flow equations without extraneous roots or missing roots. By Wu elimination method, two other groups of solutions are obtained under low-load conditions, despite the normal groups of high-voltage and low-voltage solutions. On basis of computation, V-P curve, and VPQ three-dimensional surface are obtained, as well as the stable operational area. V-Q sensitivity analysis method is used to analyze the stability under different operational conditions. The properties of Jacobian matrix are also analyzed in this paper.

Key words： Wu elimination method power flow equations V-P curve V-Q sensitivity analysis Power flow Jacobian matrix
