Mitigating Extraordinary Events using Wide Area Monitoring Applications

Increased understanding of extraordinary events in the electrical power system is vital in order to develop and assign appropriate remedies to limit the presence and consequences of such events in the future. In this paper extraordinary events are discussed in a generalised way, describing sequence and causes of historical events. Results from a dynamic study of an improved description of the IEEE Reliability Test System 1996 are used to illustrate the importance of proper representation of a power systems dynamic behaviour in order to be able to study consequences of extraordinary events and the development of various remedial applications based on Wide Area Monitoring Systems.
