Assessment of Transient Stability via Stochastic Approach and its Application to Optimum Load Dispatching Problem in Power Systems

Abstract

This paper describes a method of transient stability evaluation via the stochastic approach developed for the application to security control, and the method is applied to a model system. A comparison was made between the results obtained by the method here proposed and by the pattern recognition method proposed recently for the same purpose. The superiority of the former was ascertained. Furthermore, as an example of a practical application of this method, it was applied to the optimum load dispatching problem, considering not only economy but also transient stability.
