DESCRIPTION:Title: Fast Fingerprints for Power System Events\nSpeaker:
	 David Bindel\nAbstract: In order to operate the power grid aggressively
	 enough to make full use of renewable power\, operators need new tools
	 for situational awareness and control.  Phasor measurement units (PMUs)
	 have been developed for the past thirty years\, but first saw wide-scale
	 production grade deployments in the US after DOE investments funded by
	 the American Recovery and Reinvestment Act of 2009.  PMUs report voltage
	 and current phasors thirty or more times every second\, promising
	 operators a real-time picture of the state of the grid -- but only with
	 systems and algorithms that transmit the data and analyze this
	 information at similar rates. In this talk\, we describe fast analysis
	 using PMU-sensed \"fingerprints\" of different types of system events 
	 (e.g. changes in line status or reconfiguration of substations).  Our
	 system\, FLiER (Fingerprint Linear Estimation Routine) identifies system
	 changes in close to real time through a novel filtering operation that
	 lets us discard most potential events from consideration with little
	 computation. We describe the elements of our approach\, as well as
	 giving an overview of work in progress to improve the quality of our
	 results (and the range of contingencies we can handle) by monitoring the
	 frequency content of transient \"ringing\" as the system passes from one
	 state to another.
