Selection of multiple credible contingencies for real time contingency analysis

The need to increase situational awareness in power systems is more evident than before. Increased power system complexity and integration of intermittent resources have contributed to the emerging need to monitor power systems in real time. Real time contingency analysis can increase situational awareness by monitoring the power system in real time and alarming the operators of the impending problems. Monitoring all multiple contingencies in real time is impossible and therefore, there is a need to reduce the number of monitored contingencies. This paper introduces a method for identifying most critical contingencies in power system for real-time monitoring.
