The Predictor Corrector Primary Dual Interior Point Method is used to solve the OPF model. The effectiveness of load shedding is confirmed using the Q-V mode analysis method, which can be applied to compute eigenvalues of a reduced Jacobian matrix. The numerical results of 2 IEEE standard test systems demonstrate that the proposed OPF model is very effective since it automatically identifies the weak buses and circuits and calculates minimum load shedding.
