A key element in the development of smart power transmission systems over the past decade is the tremendous advancement of the Wide-Area Measurement System (WAMS) technology, also commonly referred to as the Synchrophasor technology. Significant research efforts have been made on techniques to use WAMS for monitoring and situational awareness of large power networks dispersed across wide geographical areas. In contrast, use of WAMS for automatic feedback control has received less attention from the research community. The objective of this talk is to bridge this gap by formulating wide-area control problems for oscillation damping and voltage control. We will pose four distinct control-theoretic problems. The first problem will be on using PMU measurements from selected nodes in a power system to identify reliable dynamic models with related discussions on identifiability and PMU placement. The remaining three problems will be to employ these models for designing output feedback damping controllers via control inversion, model predictive control, and energy function based methods. Some initial results on how these control mechanisms may be implemented in a distributed way on top of any typical arbitrated communication network with inherent time-delays will also be presented. Results will be illustrated using examples from the US west coast grid (WECC), as well as real-time simulations from the BEN-WAMS testbed recently developed at NC State.
Aranya Chakrabortty received his B.E. degree from Jadavpur University, India in 2004, and his MS and Ph.D degrees from Rensselaer Polytechnic Institute, Troy, NY in 2005 and 2008, respectively, all in Electrical Engineering. From 2008-2009 he was appointed as a postdoctoral research associate in the Aeronautics and Astronautics department of the University of Washington, Seattle. From 2009-2010 he was a faculty member in the Electrical and Computer Engineering department of Texas Tech University, Lubbock, Texas. Since fall 2010 Aranya has joined the ECE department of North Carolina State University, Raleigh, NC as an Assistant Professor. His research interests are in all branches of control system theory and applications, with a particular focus on electric power system networks. He is currently a part of the FREEDM Systems Center in NCSU, and is involved with several system and control theoretic research problems for the US power grid using synchrophasor technology, and its integration with renewable energy sources such as wind energy. He contributes actively to NASPI (North American Synchrophasor Initiative), and is a member of IEEE Control Systems Society and IEEE Power and Energy Society.
