    Abstract

    As electric power systems become larger and more complex, they become increasingly difficult to control. The problem of transient stability has, accordingly, attracted much recent attention owing to the concerns over the possibility of multiswings occurring in longitudinal power systems such as the Japanese power grid. Although multiswings are becoming an important issue, it remains difficult to develop analytical solutions for modeling their constituent modes. One simplifying method involves using Prony analysis to resolve swings into less complex elements. In this paper, a method of stability screening is suggested in which Prony analysis and single machine equivalent (SIME) methods are used to evaluate the risk of step-out by calculating the area between the swing curve trajectory and the time axis by using a series of estimated values. The validity of this proposed method is verified by simulation on a 10-machine, 47-bus system.
