Abstract This paper presents the effects of five different modifications to the standard Newton-Raphson (NR) method for the solution of load flows in ill-conditioned power systems. The proposed modifications to the NR method are: (1) NR method with decelerated convergence; (2) accelerated method for Newton's method at singular points (two-step algorithm and three-step algorithm); (3) Broyden's Jacobian-updating procedure for the NR method; (4) constant positive shift algorithm; (5) increasing… CONTINUE READING
