GlobalSIP 2013 Symposium on:

Information Processing in the Smart Grid

[Download the PDF Call for Papers]

Communication and information technologies are taking an increasingly important role in monitoring and controlling physical systems. The smart grid is a canonical example of a cyber‐physical system (CPS) in which the physical power grid is monitored by a network of sensors and other intelligent devices to dynamically track and control the network to ensure near‐perfect reliability. In contrast to the traditional grid in which generation, transmission, and distribution are clearly distinct and managed by well‐defined entities, the smart grid 1) allows integration of renewables (e.g., solar, wind) at all points on the grid (transmission, distribution and consumer premises); 2) enables consumers to manage their own energy resources and consumption via a host of new technologies and tools; 3) provides wide‐area situational awareness to grid operators; and 4) automates key decision‐marking processes at all layers of the grid. To realize these transformations, the smart grid is built on a vast cyber infrastructure that supports secure, reliable, and real‐time information processing throughout the power grid. The Signal Information Processing (SIP) Community will play a key role in architecting this key end‐to‐end communications, control, and computation (cyber) network that overlays and functions in synchrony with the power grid.

This symposium will focus on research and innovation results for the design of the power grid’s cyber infrastructure. It aims to bring together a mix of researchers from the SIP community and from other related fields to exchange novel ideas and explore innovative ideas in architecting key technologies in tomorrow’s power grid.

Keynote Speakers

Steven H. Low, California Institute of Technology, Power System Dynamics as Primal-Dual Algorithm for Optimal Load Control

We formulate an optimal load control (OLC) problem in power networks where the objective is to minimize the aggregate cost of tracking an operating point subject to power balance over the network. We prove that the swing dynamics and the branch power flows, coupled with frequency-based load control, serve as a distributed primal-dual algorithm to solve OLC. Even though the system has multiple equilibrium points, we prove that it nonetheless converges to an optimal point. This result implies that the local frequency deviations at each bus convey exactly the right information about the global power imbalance for the loads to make individual decisions that turn out to be globally optimal. It allows a completely decentralized solution without explicit communication among the buses. Simulations show that the proposed OLC mechanism can resynchronize bus frequencies with significantly improved transient performance.

Lang Tong, Cornell University, Man in the Middle Attacks on a Power Grid: Attack Mechanisms and Counter Measures

A defining feature of a smart grid is its ability to adapt to changing operating conditions and contingencies by leveraging advanced sensing, communication, and networking capabilities. However, relying networking for grid monitoring and real time operation comes with increasing security risks of cyber-attacks.

In this talk, we consider man-in-the-middle attacks on the power grid where an adversary manipulates analog and digital data with the goal of misleading the control center with an incorrect network topology and operating state. Two types of attacks are considered. The first type of attacks avoid detection by the control center and covertly change the system operating state. The second type of attacks openly attack the control center but hide the actual source of attack. We discuss the impacts of man-in-the-middle attacks on market operations and possible counter measures of such attacks.
