Prof. Yoash Levron, Technion Bio: Yoash Levron received the B.Sc. (summa cum laude) degree in Electrical Engineering from the Technion in 2001, and the M.Sc. and Ph.d. degrees in Electrical Engineering from Tel-Aviv University in 2007 and 2013 respectively. In the years 2013-2014 he was a Postdoctoral Fellow at the Colorado power electronics center, at the University of Colorado, Boulder. He is currently an Assistant Professor in the Department of Electrical Engineering at the Technion – Israel Institute of Technology, Haifa, Israel. Dr. Levron has received several awards, including the group award of ‘Israel Security’ in 2008 and 2010, the Technion Viterbi fellowship for nurturing future faculty members (2013-2014), and the Taub fellowship for leaders in science and technology (2015). His research interests include power systems monitoring and estimation, power systems dynamics and control, and power electronics for renewable sources. |

This talk discusses several recent methods for modeling dynamic events in large interconnected power systems. Dynamic phenomena in large power systems may be highly complex, and are modeled using varying levels of abstraction, with an objective to find a good balance between accuracy and computational complexity. The most basic model is the static one, in which voltages and currents are assumed to be nearly sinusoidal, and are represented by phasors. On the other extreme, transient simulations may be very detailed, and view a power system as a set of differential equations.
This talk presents a third type of model based on the concept of "dynamic phasors". This model assumes time varying amplitudes and phases, and is shown to be the middle ground between static models and transient models in terms of accuracy and speed. Based on these concepts, I will also present a new method for modeling power networks by dynamic phasors in the direct-quadrature-zero (DQ0) reference frame.
This model extends the classic power flow equations, and accurately restates them for time-varying systems. This theorem generalizes the quasi-static approximation, and enables fast and accurate models based on dynamic phasors.
