In the emergency control, the assessment of the stability margin of the systems is a very crucial but difficult task. Actually, it is even difficult for us to define a reasonable concept of the stability for the systems when a sustained serious disturbance occurs and finally results in an emergency alarm. Usually, in such an emergency occurs, the structure of the systems will be destructed constantly until the disturbance is cleared. Hence, the system models are usually unavailable for the stability assessment of the disturbed systems. This talk introduces some aspects of the basic progress in this area. Several problems are proposed for further studies.
