ECE Seminar: Streaming Analytics for the Smart Grid
Tuesday, October 30, 2018 - 12:00pm to 1:00pm
Le Xie, Professor and Eugene Webb Faculty Fellow in the Department of Electrical and Computer Engineering at Texas A&M University
How to conduct real-time analytics of streaming measurement data in the power grid? This talk offers a dynamic systems approach to utilizing data of different time scale for improved monitoring of the grid cyber and physical security. The first example of the talk presents how to leverage synchrophasor data dimensionality reduction and Robust Principal Component Analysis for early anomaly detection, visualization, and localization. The second example presents an online framework to detect cyber attacks on automatic generation. A cyber attack detection algorithm is designed based on the approach of Dynamic Watermarking. The detection algorithm provides a theoretical guarantee of detection of cyber attacks launched by sophisticated attackers possessing extensive knowledge of the physical and statistical models of targeted power systems. The underlying theme of the work suggests the importance of integrating data with dynamic context-aware models in the smart grid.
