Abstract
With increasing penetration of grid-edge distributed energy resources (e.g., solar panels and electric vehicles), the control and protection of the future distribution grid will need to properly function not only during normal conditions, but also under a wide range of contingencies that may arise from both end point supply/demand intermittency and cyber intrusions. We propose a framework for re-designing the control and protection to deal with two-way uncertain power flows and end-point adversaries. In particular, we introduce a deep reinforcement-learning-based adaptive relay that can perform two orders of magnitude better than conventional relays in solar-rich distribution grids. We also introduce an active cyber-defense mechanism based on dynamic watermarking for power electronically-interfaced distribution systems. This would potentially pave the way for much more residential PV and EV integration while the resiliency of the grid at large remains intact or improved.
Biography
Dr. Le Xie is a Professor and Eugene Webb Faculty Fellow in the Department of Electrical and Computer Engineering at Texas A&M University. He received B.E. in Electrical Engineering from Tsinghua University in 2004, S.M. in Engineering Sciences from Harvard in 2005, and Ph.D. in Electrical and Computer Engineering from Carnegie Mellon in 2009. His industry experience includes ISO-New England and Edison Mission Energy Marketing and Trading. His research interest includes modeling and control in data-rich large-scale systems, grid integration of clean energy resources, and electricity markets. Dr. Xie received the U.S. National Science Foundation CAREER Award, and DOE Oak Ridge Ralph E. Powe Junior Faculty Enhancement Award. He was awarded the 2017 IEEE PES Outstanding Young Engineer Award. He was the recipient of the Texas A&M Dean of Engineering Excellence Award, ECE Outstanding Professor Award, and TEES Select Young Fellow. He is an Editor of IEEE Transactions on Smart Grid, and the founding chair of the IEEE PES Subcommittee on Big Data & Analytics for Grid Operations. He and his students received the Best Paper awards at North American Power Symposium 2012, IEEE SmartGridComm 2013, and HICSS 2019. He chaired the 2018 NSF Workshop on Real-time Learning and Decision Making in Dynamical Systems.
