Power system transient stability assessment – traditional vs modern methods

Abstract Different types of power system stability are identified, and transient stability is found to be the one which imposes the most stringent requirements. The three classes of approaches to transient stability assessment are also identified, and their ability to meet such requirements is examined. It is found that they can be met by appropriate combinations, lying at the crossroads of numerical, direct, and automatic learning methods. It is also found that many of the combinations advocated for the purpose of transient stability are readily adaptable to other stability problems. Finally, a general approach is suggested, where all types of stability would be handled in a unified way.
