DESCRIPTION:Prof.  Ali Abur - Northeastern University Boston\, MA\, USA\n
 Bio: Ali Abur obtained his B.S. degree from Orta Dogu Teknik Universitesi\
 , Ankara\, Turkey in 1979 and both his M.S. and Ph.D. degrees from the Ohi
 o State University in 1981 and 1985 respectively. He was a faculty member 
 at Texas A&M University until November 2005 when he joined the faculty of 
 Northeastern University as a Professor and Chair of the Electrical and Com
 puter Engineering Department. His research and educational activities have
  been in the area of power systems. He is a Fellow of the IEEE for his wor
 k on power system state estimation. He co-authored a book and published wi
 dely in IEEE journals and conferences. He was on the Editorial Board of IE
 EE Transactions on Power Systems and Power Engineering Letters during 1999
 -2011. He is an IEEE PES Distinguished Lecturer.\nAbstract: Phasor measure
 ments are quickly populating the transmission substations and creating new
  opportunities as well as some challenges for power system operators and d
 esign engineers. In this talk we will describe the utilization of phasor m
 easurements for the specific application of state estimation that we have 
 investigated in the recent years. One of the main features of phasor measu
 rements that distinguish them from SCADA counterparts is their time-stamps
 \, making it possible to directly measure the phase angles of bus voltages
  at a high scan rate of 30 or more times a second. Noting that SCADA scans
  are typically every few seconds\, the phasor measurement scan rate opens 
 up possibilities of near real-time tracking\, prediction of both the syste
 m states as well as network model. Use of phasor measurements also simplif
 ies the estimation formulation which in turn also facilitates implementati
 on of some alternative robust estimation methods which have so far not bee
 n widely considered due to their computational disadvantages when applied 
 to SCADA measurements. Use of phasor measurements also enables utilization
  of modal domain solutions paving the way to simple extension of estimatio
 n procedures to unbalanced multi-phase power grid monitoring. Finally\, we
  note some results on the use of phasor measurements at area boundaries an
 d formulation of a sparse estimation problem in order to detect and identi
 fy major line outages in external network model. Such unreported outages a
 re known to have a significant impact the static security analysis results
 . The talk will include numerical examples to illustrate the discussed pro
 cedures and solutions when applied to typical power systems.
