A Complex Network View of the Grid
The grid is a complex interconnected infrastructure, a system of systems. In this talk we will first extract network scientific metrics regarding the grid admittance by compiling, in a statistical model, key features of several samples of grid topologies and electrical characteristics. One of the interesting findings is that power grids are characterized by nodes that have what we call "high electrical centrality," which has a direct impact on the intensity of flows in certain portions of the grid. We examine the significance of this finding in terms of the electrical behavior of the grid, trying to shed light on the importance of different assets in shaping the power flow and how measuring these quantities is crucial for recovering reliably the network state. We also look how one could shed light on the grid cascading behavior, by considering how the operating conditions can affect congestion.
Professor Anna Scaglione (M.Sc.'95, Ph.D. '99) is currently Professor in Electrical and Computer Engineering at University of California at Davis. She joined UC Davis in 2008, after leaving Cornell University, Ithaca, NY, where she started as Assistant Professor in 2001 and became Associate Professor in 2006. Prior to joining Cornell she was Assistant Professor in the year 2000-2001, at the University of New Mexico. Dr. Scaglione is a Fellow of the IEEE since 2011 and was honored by both the Signal Processing and the Communication Societies. She is the Editor-in-Chief of the IEEE Signal Processing Letters, and served as Associate Editor for the IEEE Transactions on Wireless Communications from 2002 to 2005, and from 2008 to 2011 in the Editorial Board of the IEEE Transactions on Signal Processing from 2008, where she was Area Editor in 2010-11. She has been general chair of the workshop SPAWC 2005 in the Signal Processing for Communication Committee from 2004 to 2009, has been part of the SmartGridComm steering committee since 2010, and is currently in the Board of Governors of the Signal Processing Society. Dr. Scaglione is the first author of the paper that received the 2000 IEEE Signal Processing Transactions Best Paper Award. She has also received the NSF Career Award in 2002, is co-recipient of the Ellersick Best Paper Award (MILCOM 2005), and co-recipient of the 2013 IEEE Donald G. Fink Prize Paper Award. Her expertise is in the broad area of signal processing for communication systems and networks. Her current research focuses on studying and enabling decentralized learning and signal processing in networks of sensors. Dr. Scaglione also focuses on sensor systems and networking models for the demand side management and reliable energy delivery.
The seminar series is presented by the Trustworthy Cyber Infrastructure for the Power Grid (TCIPG) Project, an $18 million multi-university research effort whose partner institutions include the University of Illinois at Urbana-Champaign, Arizona State University, Dartmouth, and Washington State University. The TCIPG Project, a successor to the earlier NSF-funded TCIP Center, was founded in 2009 with support from the U.S. Department of Energy and the U.S. Department of Homeland Security. It is housed in the Information Trust Institute, University of Illinois at Urbana-Champaign.
