March – April 2014
Dr. Masoud Honarvar Nazari, Post Doctoral Fellow
Georgia Institute of Technology
When: Friday, March 7, 2014 at 3:05 p.m.
Where: Warnock 1230
In this talk, I will first discuss needs for transforming today’s fossil-fuel dependent and highly polluting electric power systems into sustainable, efficient, and reliable electric energy systems, which have functionalities similar to Internet.
Next, I will present my recent efforts to design a distributed decision-making and control architecture for internet-like energy systems. I will discuss the fundamental differences between internet-like distribution energy systems and conventional transmission power systems, regarding dynamic behavior under a high penetration of distributed generators.
Then, I will present a novel distributed frequency regulation architecture, whereby frequency regulators communicate with their neighbors in the network in order to improve performance. I will show that despite the frequency regulators being distributed, stability can be ensured while avoiding inter-area oscillations using a limited control effort. The efficacy of the proposed frequency regulation framework is shown through simulations on two real-world electric energy systems of different scale and complexity.
Masoud Honarvar Nazari is a Post Doctoral Fellow in the School of Electrical and Computer Engineering at Georgia Institute of Technology. He received his first Ph.D. in Electrical and Computer Engineering in a joint program between Carnegie Mellon University and the University of Porto, Portugal in 2012 and obtained his second Ph.D. in Engineering and Public Policy from Carnegie Mellon in the same year. He was a visiting scholar at MIT Energy Initiative in 2010. He was also awarded the five-year international FCT (Fundação para a Ciência e a Tecnologia) fellowship in 2007. His research interests include Power System and Smart Grid operation; Distributed Control Architecture for Internet-like Energy Systems; Large-scale Integration of Distributed Energy Sources, and; Policy implication and regulation design for modernizing Electric Power Systems. He has several book chapters, journals, and conference papers in the subject of Power System Stability and Control.
Mr. Tom Armstrong, Chief Technologist for Broadband Communication Systems
Applied Signal Technology – Raytheon Space and Airborne Systems
When: Monday, March 17, 2014 at 3:05 p.m.
Where: Warnock 1230
The Global Telecommunication Network touches our lives daily, and many do not appreciate the complexity of the network. This talk introduces fundamental engineering concepts of the network in a simplified view, and shows that the evolution of the core network in meeting today’s communication needs has not changed since the late 1800s.
Tom Armstrong is the chief technologist for Broadband Communication Systems in the Applied Signal Technology mission area of Raytheon Space and Airborne Systems. In this role, he provides direction and vision in all technical aspects of signal communications and intelligence product and system development and deployment: aspects including product design, system integration and test, operations and maintenance, and mission management and analysis. He is also a Raytheon Applied Signal Technology Senior Fellow and in such capacity he directs research and development in advanced modulation, high speed switching, error correction, signal multiplexing, communication protocols, and signal processing technologies.Prior to joining Raytheon Applied Signal Technology in 1999, Armstrong enjoyed a twelve-year career at the U.S. Department of Defense. He served in many technical capacities. In his final position with the DoD, he served as Technical Director of one of the operational divisions where he oversaw all aspects of design, development, and deployment of multiple signal communications systems. Mr. Armstrong earned his bachelor and master degrees in electrical engineering from the University of Utah in 1986 and 1987, respectively. On two different occasions—in 1997 and again in 2004—he received a Meritorious Citation from the US Government for exceptional achievement and superior performance which contributed significantly to the deployment of a major technical system of national importance.
Dr. Willie Padilla, Professor
Dept. of Physics, Boston College
When: Friday, April 4, 2014 at 3:05 p.m.
Where: Warnock 1230
Metamaterials are artificial electromagnetic materials which have realized exotic electromagnetic responses including negative index of refraction and invisibility cloaking. As the underlying physics of these fascinating materials continues to be uncovered, effort is now shifting toward demonstration of devices. I will present the design, fabrication, and demonstration of active metamaterials that function as a real-time tunable, spectrally sensitive spatial masks for use in THz imaging with only a single pixel detector.
Willie Padilla received a PhD from the UC San Diego and was a Director’s Postdoctoral Fellowship at Los Alamos National Laboratory. In 2006 he joined the Department of Physics at Boston College and is a Full Professor. In 2007 he was awarded a Young Investigator Award from the Office of Naval Research and Presidential Early Career Award for Scientists and Engineers in 2011. In 2012 he was elected a Fellow of the Optical Society of America and a Kavli Frontiers of Science Fellow in 2013.
