Improving Damping of Power Networks: Power Scheduling and Impedance Adaptation

June 25, 2012
EE Conference Room
Hosted by: Columbia University Joint CS/EE Networking Seminar
Speaker: Enrique Mallada , Ph.D. candidate (Cornell University)


This work studies the effect of power scheduling and line impedances on the damping of a power network. We relate the damping of a network with the algebraic connectivity of a state dependent Laplacian. Via implicit function theorem, we further characterize its dependence on network parameters. This allows us to derive several updating directions that can locally improve the damping. The analysis also provides some interesting insight. For example, improving connectivity, by adding lines for instance, may not be beneficial in terms of damping.

Speaker Biography

Enrique Mallada received the degree of Telecommunications Engineer from Universidad ORT, Uruguay, in 2005. From 2004 to 2007, he was an IT Specialist at IBM; in 2008, he worked as an Engineer at the Traffic Engineering Department of ANTEL, the main telecommunications operator in Uruguay. He also was a Teaching and Research Assistant at the Department of Telecommunications at Universidad ORT, where he was also a member of the MATE research group. He has been in the M.S/Ph.D program in the School of Electrical and Computer Engineering at Cornell University since August, 2008. He is currently a member of the Networks Group led by Dr. A. Kevin Tang, member of the FoIE Group and coordinator of the ISN Seminar. He was a summer intern at IBM T. J. Watson Research Center during summer 2011. His research interests include networks, control, nonlinear dynamics and optimization.
