Convergence Region of Newton Iterative Power Flow Method: Numerical Studies

Figure 10

The convergence region and the number of iterations needed for the FDPF method to converge at different loading conditions on ( ) plane: (a) the lightly loaded condition, ; (b) ; (c) ; (d) the heavily loaded condition, . From an initial condition, the number of iterations required by the FDPF method increases with the increase of loading condition.
