Methods for estimating stability regions with applications to power systems

A specialized method for constructing a hyper-ellipse that resides inside the stability regions of a class of nonlinear autonomous systems such as electric power systems is provided. This method is further generalized to estimate the stability region of a fairly general class of high dimension nonlinear autonomous systems. Applications of the introduced results to power system transient stability analysis are described, together with numerical examples. Copyright © 2006 John Wiley & Sons, Ltd.
