If you have a question about this talk, please contact Fulvio Forni. Recent advances in the theory for stability region estimation for several classes of nonlinear dynamical systems, including two-time-scale DAE systems will be presented. An effective methodology, termed BCU , for on-line transient stability assessment (TSA) and enhancement of a large set of contingencies at operating points obtained from state estimators will be presented. A critical evaluation of this methodology using a practical utility model as a fast screening and ranking method has been performed. This evaluation study is the largest in terms of system size—14,500 buses and 3000 generators—for a practical on-line transient stability assessment application. The evaluation results, performed on 5.3 million contingencies, were very promising in terms of speed, accuracy, reliability, and robustness. This study also confirms the practicality of a theory-based methodology for on-line TSA of large-scale power systems. More than a dozen on-line TSA systems have been installed in large utility companies. Extensions of the BCU methodology to modern power grids with IBRs will be discussed. The seminar will be held in the JDB Seminar Room, Department of Engineering, and online (zoom): https://newnham.zoom.us/j/92544958528?pwd=YS9PcGRnbXBOcStBdStNb3E0SHN1UT09 This talk is part of the CUED Control Group Seminars series.
