A fast Newton-FGMRES method for power flow calculations is proposed in this paper. Three accelerating schemes to speed up the Newton-FGMRES method are proposed. Numerical studies show that the proposed fast Newton-FGMRES method consistently outperforms the traditional Newton-GMRES method and Newton-LU method on two practical power systems-one with 12 000 buses, another with 21 000 buses. For the 21 000-bus system, the fast Newton-FGMRES method can be 45.7% faster than the traditional Newton-LU method.
