Dynamic decision-event trees for rapid response to unfolding events in bulk transmission systems

In order to defend against rare but catastrophic power system events, this paper proposes a generalization of the system protection scheme (SPS) that the authors call the dynamic decision-event tree (DDET). As a new adaptive approach, DDET takes rapid response to unfolding events before they degenerate into uncontrolled cascading, islanding or load interruption. The basic concept, together with some implementation issues, are described and discussed within this paper.
