Smart Grid (SG) systems have drawn the attention of academia, industry and government agencies due to the great impact of such systems on society, economics and the environment. These next generation systems integrate control, communication and computation to achieve stability, efficiency and physical robustness. The increased dependency of the control of physical processes upon communication networks make them vulnerable to various cyber-threats. We present an SG cyber-physical security (CPS) framework based on a cross-layer perspective. Data acquired at the physical layer is interpreted at the cyber domain layer, which uses high-level functions to analyze data, implement distributed state estimation, and use robust control to generate new protective actions between the physical subsystems. A novel Distributed Software-Defined Network (DSDN) framework is used to leverage data, network monitoring statistics and machine learning to detect abnormal behavior of the SG communication network. The DSDN then prompts corrective actions within the physical access devices. Our real-time, distributed approach will respond to protect the system in real-time for both failures and attacks. This novel CPS approach creates new pathways for research in physical systems. (This Project is supported by the National Science Foundation under Grant Number 1809739.)
Dr. Janise McNair is an Associate Professor in the department of Electrical & Computer Engineering at the University of Florida. She received the B.S. and M.S degrees from the University of Texas at Austin, in 1991 and 1993 and the Ph.D. degree from the Georgia Institute of Technology in 2000. Since then, Dr. McNair has been on faculty at the University of Florida, where she leads the Wireless And Mobile (WAM) Systems Laboratory. Her lab conducts systems research on smart grid, small satellites, 5G/6G, Internet of Things, and mobile social networks. She has participated in a DARPA Computer Science Study Group project, and is currently a member of the Intelligence, Science and Technology Group of the National Academy of Sciences, Engineering and Medicine. McNair has served on several conference organizing committees (IEEE SmartGridComm, IEEE INFOCOM, and others), editorial boards, and steering committees (IEEE Transactions on Mobile Computing). She is a senior member of IEEE and a member ACM.
