In his lecture, “Modeling Cascading Failure in Power Systems from a Network Perspective”, Prof. Tse first provided a historical data of blackouts in North America (1996 and 2003) provide real failure propagation profiles which contain some stereotypical features. He also presented and highlighted a network-based model, combining a deterministic physical model for power flow simulation and stochastic methods for estimating failure dynamics, is able to reproduce cascading failure dynamics that capture key features of realistic blackouts. Then Prof. Tse discussed that the 2016 Ukranian blackout was confirmed to have been triggered by cyber attacks, it is thus highly relevant to consider a cybercoupled power system model, which can be conveniently obtained from extending the network-based model, resulting in an effective simulation model that can be used to capture key features of the dynamics of failure propagation in cyber-coupled power systems. He finally concluded with an outlook of the future work.
