“Computational and Analytical Tools for Resilient and Secure Power Grids”

Speaker: Saleh Soltan (Princeton)

Abstract: In this talk, I provide an overview of the challenges facing the power grid resilience and security, and present some of our recent analytical results to address these challenges. I mainly focus on two of our recent works on power grid state estimation following a cyber-physical attack (based on papers in ACM SIGMETRICS’15, IEEE Trans. Control of Networked Systems 2017&2018, IEEE Trans. Network Science and Engineering 2018, and IEEE PES-GM’17&’18) and power grid Islanding (based on a paper in ACM-SIAM SODA’17). In the first part of the talk, I demonstrate that by leveraging the algebraic properties of the power flow equations and graph theory, the state of the grid can be efficiently estimated based on partial information after a cyber-physical attack. In the second part, I show that using convex graph embedding, the power grid can be efficiently partitioned into two balanced almost equal sized islands. Such islanding scheme can be exploited at the time of stress to stop the failures from cascading.

Speaker Bio: Saleh Soltan is a postdoctoral research associate in the department of Electrical Engineering at Princeton University. He obtained his Ph.D. in Electrical Engineering from Columbia University in 2017. He received the B.S. degrees in Electrical Engineering and Mathematics (double major) from Sharif University of Technology, Iran in 2011 and the M.S. degree in Electrical Engineering from Columbia University in 2012. He is the Gold Medalist of the 23rd National Mathematics Olympiad in Iran (2005) and the recipient of Columbia University Electrical Engineering Armstrong Memorial Award (2012) and Jury Award (2018).
