Newton downhill method
Witryna3 gru 2008 · Newton-Raphson Method is a widely used power flow method for the load flow analysis, but for the particular topology structure of the radial power distribution … WitrynaA new kind of inversion formula containing VS/VP as the inversion parameter is proposed, by which VS can be estimated in terms of the new inverted parameter. Due to the nonlinear relationship between the new inverted term and the VS, the Newton downhill method is used to solve the nonlinear problem.
