Scalable monitoring and kernel learning for energy grids

Vassilis Kekatos
Department of Electrical and Computer Engineering
University of Minnesota

12:00pm-1:00pm, Thursday, 13 March 2014, ITE 325b, UMBC

The smart grid vision urges for enhanced situational awareness, sustainability, and economics over our energy systems. While meters are being installed throughout the grid, algorithms that can effectively process this big data deluge are now demanded. Aligned to that end, this talk focuses first on scalable grid monitoring. Albeit control centers monitor their local grids independently, deregulation and renewables call for power system state estimation (PSSE) at the interconnection level. To address the complexity and communication challenges involved, a decentralized PSSE framework based on the alternating direction method of multipliers has been developed. Beyond conventional least-squares, our framework can identify outliers and circuit breaker statuses as verified on IEEE grids having thousands of nodes. Electricity market inference is the second theme of this talk. We will first demonstrate how grid topologies can be revealed using only publicly available real-time energy prices. This becomes feasible after recognizing that the price matrix can be factorized as the product of the grid Laplacian times a low-rank and sparse matrix. Leveraging the link between energy markets and the underlying physical grids, we will then cast day-ahead price forecasting as a kernel learning task. Through a novel nuclear norm-based regularization, kernels across pricing nodes and hours are systematically selected. Numerical tests using real data from the Midwest ISO market corroborate the interpretative merits of our schemes.

Dr. Vassilis Kekatos is currently a postdoctoral associate with the ECE Dept. of the University of Minnesota, Minneapolis. He obtained his Ph.D. in Computer Engineering and Science from the University of Patras, Greece, in 2007. In 2009, he received a Marie Curie fellowship. During the summer of 2012, he worked as a consultant for Windlogics Inc.

talk: Probabilistic Information for Spectrum Sensing and Utilization, 11:45 3/7, UMBC

Exploiting Probabilistic Information for Spectrum Sensing
and Utilization: towards Efficient Wireless Coexistence

Prof. Xiangwei Zhou
University of Illinois, Carbondale

11:45am Friday, 7 March 2014, ITE 325b, UMBC

With the rapid growth of wireless devices and applications, the electromagnetic radio spectrum is considered to be in short supply. To overcome spectrum scarcity and satisfy emerging user demands, cognitive radio, which can sense and adapt to the surrounding spectral environment, has been introduced to enhance the utilization of the spectrum. However, it is a challenging task to design a robust and cost-effective system involving identification and reuse of spectrum opportunities changing over time, frequency, and space. In this talk, I will focus on efficient spectrum sensing and utilization techniques for dynamic spectrum access. In particular, I will emphasize the importance of exploiting probabilistic information unique to such a system. I will present novel techniques from the perspectives of both a single user and a multi-user network. In the end, I will discuss further extension of the work to enable the coexistence of heterogeneous wireless networks.

Toward strong, usable access control for personal data

Michelle Mazurek
Carnegie Mellon University

1:00pm Thursday, 6 March 2014, ITE 325b, UMBC

Users create, store and access a lot of personal data, both on their devices and in the cloud. Although this provides tremendous benefits, it also creates risks to security and privacy, ranging from the inconvenient (private photos posted around the office) to the serious (loss of a job; withdrawal of college admission). Simply refusing to share personal data is not feasible or desirable, but sharing indiscriminately is equally problematic. Instead, users should be able to efficiently accomplish their primary goals without unnecessarily compromising their privacy. In this talk, I describe my work toward developing usable access-control mechanisms for personal data. I review the results of three user studies that provided insight into users’ policy needs and preferences. I then discuss the design and implementation of Penumbra, a distributed file system with built-in access control designed to support those needs. Penumbra has two key building blocks: semantic-tag-based policy specification and logic-based policy enforcement. Our results show that Penumbra can enforce users’ preferred policies securely with low overhead.

Michelle Mazurek is a Ph.D. candidate in Electrical and Computer Engineering at Carnegie Mellon University, co-advised by Lujo Bauer and Greg Ganger. Her research interests span security, systems, and HCI, with particular emphasis on designing systems from the ground up for usable security. She has worked on projects related to usable access control, distributed systems, and passwords.
