Abstract :
A fast Newton-FGMRES method for power flow calculations is presented in this paper. Three accelerating schemes to speed up 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 12000 buses, another with 21000 buses-indicating that the proposed fast Newton-FGMRES method can be a good alternative to power flow calculations.
