DESCRIPTION:Prof. Yoash Levron (Technion - Israel Institute of Technology)
 \nAbstract:\nThis talk discusses several recent methods for modeling dynam
 ic events\nin large interconnected power systems. Dynamic phenomena in lar
 ge\npower systems may be highly complex\, and are modeled using varying\nl
 evels of abstraction\, with an objective to find a good balance\nbetween a
 ccuracy and computational complexity. The most basic model is\nthe static 
 one\, in which voltages and currents are assumed to be\nnearly sinusoidal\
 , and are represented by phasors. On the other\nextreme\, transient simula
 tions may be very detailed\, and view a power\nsystem as a set of differen
 tial equations. This talk presents a third\ntype of model based on the con
 cept of "dynamic phasors". This model\nassumes time varying amplitudes and
  phases\, and is shown to be the\nmiddle ground between static models and 
 transient models in terms of\naccuracy and speed. Based on these concepts\
 , I will also present a new\nmethod for modeling power networks by dynamic
  phasors in the\ndirect-quadrature-zero (DQ0) reference frame. This model 
 extends the\nclassic power flow equations\, and accurately restates them f
 or\ntime-varying systems. This theorem generalizes the quasi-static\nappro
 ximation\, and enables fast and accurate models based on dynamic\nphasors.
 \nShort Bio:\nYoash Levron received the B.Sc. (summa cum laude) degree in 
 Electrical\nEngineering from the Technion in 2001\, and the M.Sc. and Ph.d
 . degrees\nin Electrical Engineering from Tel-Aviv University in 2007 and 
 2013\nrespectively. In the years 2013-2014 he was a Postdoctoral Fellow at
 \nthe Colorado power electronics center\, at the University of Colorado\,\
 nBoulder. He is currently an Assistant Professor in the Department of\nEle
 ctrical Engineering at the Technion – Israel Institute of\nTechnology\, 
 Haifa\, Israel. Dr. Levron has received several awards\,\nincluding the gr
 oup award of ‘Israel Security’ in 2008 and 2010\, the\nTechnion Viterb
 i fellowship for nurturing future faculty members\n(2013-2014)\, and the T
 aub fellowship for leaders in science and\ntechnology (2015). His research
  interests include power systems\nmonitoring and estimation\, power system
 s dynamics and control\, and\npower electronics for renewable sources.
