Abstract

Based on the classical model of multi-machine power system with uniform damping, by the aid of the Lagrange Mean Value Theorem and LaSalle Invariance Principle, we present a method for constructing a closed hyper-ball that strictly resides in transient stability domain. This method is termed first order upper bounding function method. First of all, we derive the analytical expression and computational step of the approximated stability region. Three numerical examples are provided in the end, the result of simulation reveals that the method in this paper is strict and reliable although conservative to some extent. The remarkable merit of this method is its simplicity and reliability, and furthermore, the method avoids the difficulty of computing UEP that is essential in traditional transient energy function methods.
