A new methodology for the purpose of real-time local control of transient stability

A new methodology is introduced solely for use in real-time local control of transient stability. The proposed method is based on localized transient stability of a power system. This is a completely new idea. In this method, the postfault power system is represented by a two-generator localized power system at the site of each individual generator. If each of these localized power systems reaches its stable equilibrium, then the power system reaches its stable equilibrium. Therefore, in terms of real-time local control of transient stability, if each of the localized power systems is driven to its respective stable equilibrium by local control actions with local computations using the locally measured data, then the power system is in stable equilibrium. Thus the method can be easily implemented for real-time local control of transient stability. This paper primarily focuses on the basic concepts of the method and presents some preliminary test results.
