Prof. Zussman will give a Distinguished Lecture at the IEEE GlobalSIP 2018 Symposium on Information Processing, Learning and Optimization for Smart Energy Infrastructures.
The lecture will focus on resilience of the power grid to cyber and physical attacks. The abstract is below.
Power Grid State Recovery following a Joint Cyber and Physical Attack
Abstract: We focus on joint cyber and physical attacks on power grids and present methods to retrieve the grid state information following such attacks. We consider models where an adversary attacks an area by (i) physically disconnecting some of the power lines, and (ii) blocking/modifying the measurements from monitoring devices within the area to mask the line failures. We use tools from linear algebra and graph theory, and leverage the properties of the power flow equations to develop methods for state recovery. Namely, using information observed outside of the attacked area, these methods recover information about the disconnected lines and the state inside the attacked area. We identify sufficient conditions on the area structure and constraints on the attack characteristics such that these methods can correctly recover the state. We consider the DC and AC power flow models, measurement noise, and false data injection attacks, and present corresponding analytical and numerical results.
