A new pre-conditioning technique, which is used to improve the convergence performance of Newton-GMRES power flow computation, has been presented in this paper. By using four basic types of matrix splitting algorithms and the matrix inversion operation skill based on Neumann series, a new kind of pre-conditioned method based on Neumann series is proposed. The pre-conditioning technique used for power flow computation of Newton-GMRES method can significantly improve the convergence performance and the efficiency of power flow computation. Finally, the computation results of IEEE 118-bus system verifies effectiveness of the proposed method.
