A direct method for frequency stability assessment of power systems is proposed in this paper, which is based on the latest Jacobian matrix of the Newton-Raphson load flow calculation. The method can directly calculate the final system frequency after the last switching without step-by-step integral, and the system frequency stability can be determined. The proposed method has been applied to the New England 68-bus system, and the results show that the method is of good accuracy and the fine prospect of online application.
