Dr. Kenneth Hopkinson

Professor and Interim Head, Department of Electrical and Computer Engineering, Air Force Institute of Technology

Hopkinson will present, "Overcoming Communication, Distributed Systems, Simulation, and Security Challenges: A Case Study Involving the Protection and Control of the Smart Electric Power Grid". Meet and Greet to follow. Refrshements served.

Abstract: As power systems increasingly make use of computer networks, these so-called smart grid systems require new approaches to effectively test and evaluate the evolving next-generation protection and control systems in order to ensure the reliability and information security that is expected in modern critical infrastructures. This talk will discuss three efforts at the Air Force Institute of Technology (AFIT) to address these challenges. First, the presentation will discuss the development and subsequent use of the electric power and communication synchronizing simulator (EPOCHS), a distributed simulation environment, to help evaluate a new generation of communication-based protection schemes. The presentation will then go on to describe recent work to develop a trust-management toolkit, a robust and configurable protection system augmentation, which can successfully function in the presence of untrusted (malfunctioning) smart grid protection system nodes by combining reputation-based trust with network-flow algorithms to identify and mitigate faulty smart-grid protection nodes. The third portion of the talk will focus on the use of software model checking applied to smart grid protection software designs to rigorously assess their fault tolerance. The approaches we take provide valuable feedback to protection engineers during the development of new systems, for assessing the quality of competing designs, and for risk management purposes. The essential elements of the approaches taken also have broader application to distributed system problems, particular those with mission-critical requirements.

Bio: Kenneth M. Hopkinson received a B.S. degree from Rensselaer Polytechnic Institute, Troy, New York, in 1997 and M.S. and Ph.D. degrees from Cornell University, Ithaca, New York, all in Computer Science. He is a Professor of Computer Science at the Air Force Institute of Technology, Wright-Patterson AFB, Ohio, the graduate school for the Air Force. His research interests include networking, fault tolerant and reliable distributed systems, information security, the use of networks to enhance critical infrastructures, particularly in smart electric power grid protection and control systems, cognitive radios, space applications, and remote sensing.
