Binghamton Data Science TAE / IEEE PES Seminar: Integrated Dynamic State Estimation in Power Systems
December 2, 2022 @ 7:00 am - 8:00 am
To make well-informed decisions, power system operators need accurate timely estimates of the operational conditions of the power grid. Up to the present time, conventional static state estimators have been widely deployed in utility control centers to improve the estimation accuracy and expand the monitoring areas. However, these estimators are no longer sufficient for monitoring the modern power grid, which is experiencing increasing uncertainty and variation driven by the high penetration of intermittent renewable energy sources (mainly solar and wind). In fact, conventional static state estimation methods for power grids often fail to provide any useful information during transmission-line tripping and cascading grid failures when the power system rapidly changes, and state estimation results are crucially needed.
In this presentation, the conventional state estimation is reviewed. Also, a dynamic state estimation (DSE) approach is proposed that can not only estimate current operational conditions but also predict their future trends and quantify their uncertainty. To minimize the financial cost of measurement devices while achieving observability of important system states, observability and detectability studies are carried out to guide measurement placement and model selection. It is shown that many dynamic states in the power systems are marginally observable (virtually unobservable). If an observer model can be chosen to make the eigenvalues of the corresponding states stable, the DSE can still converge to the true value of the states.
