Fast contingency screening is expected to be an integral part of any practical online dynamic security analysis (DSA). Ranking of contingencies requires the use of severity indices, and for DSA such an index must be a measure of stability. From experience in static security analysis, it is well known that some indices work better than others for particular power systems and that combinations of indices usually work better than a single index. For DSA, which is still in its infancy, severity indices are more complex and very few have been tested for screening. In this paper, several indices are proposed for contingency screening in online DSA. These indices are based on the concepts of coherency, transient energy conversion between kinetic energy and potential energy and three dot products of system variables. Test results on realistic power systems show the promise of these indices in contingency screening
