DESCRIPTION:Prof. Yoash Levron\, Technion\nBio: Yoash Levron received the 
 B.Sc. (summa cum laude) degree in Electrical\nEngineering from the Technio
 n in 2001\, and the M.Sc. and Ph.d. degrees\nin Electrical Engineering fro
 m Tel-Aviv University in 2007 and 2013\nrespectively. In the years 2013-20
 14 he was a Postdoctoral Fellow at\nthe Colorado power electronics center\
 , at the University of Colorado\,\nBoulder. He is currently an Assistant P
 rofessor in the Department of\nElectrical Engineering at the Technion – 
 Israel Institute of\nTechnology\, Haifa\, Israel. Dr. Levron has received 
 several awards\,\nincluding the group award of ‘Israel Security’ in 20
 08 and 2010\, the\nTechnion Viterbi fellowship for nurturing future facult
 y members\n(2013-2014)\, and the Taub fellowship for leaders in science an
 d\ntechnology (2015). His research interests include power systems\nmonito
 ring and estimation\, power systems dynamics and control\, and\npower elec
 tronics for renewable sources.\nThis talk discusses several recent methods
  for modeling dynamic events in large interconnected power systems. Dynami
 c phenomena in large power systems may be highly complex\, and are modeled
  using varying levels of abstraction\, with an objective to find a good ba
 lance between accuracy and computational complexity. The most basic model 
 is the static one\, in which voltages and currents are assumed to be nearl
 y sinusoidal\, and are represented by phasors. On the other extreme\, tran
 sient simulations may be very detailed\, and view a power system as a set 
 of differential equations.\nThis talk presents a third type of model based
  on the concept of "dynamic phasors". This model assumes time varying ampl
 itudes and phases\, and is shown to be the middle ground between static mo
 dels and transient models in terms of accuracy and speed. Based on these c
 oncepts\, I will also present a new method for modeling power networks by 
 dynamic phasors in the direct-quadrature-zero (DQ0) reference frame.\nThis
  model extends the classic power flow equations\, and accurately restates 
 them for time-varying systems. This theorem generalizes the quasi-static a
 pproximation\, and enables fast and accurate models based on dynamic phaso
 rs.
