Talk Title: Application of Polynomial Optimization to Electricity Transmission Networks
Series: CommNetS
Abstract: Multivariate polynomial optimization where variables and data are complex numbers is a non-deterministic polynomial-time hard problem that arises in various applications such as electric power systems, signal processing, imaging science, automatic control, and quantum mechanics. Complex numbers are typically used to model oscillatory phenomena which are omnipresent in physical systems. We propose a complex moment/sum-of-squares hierarchy of semidefinite programs to find global solutions with reduced computational burden compared with the Lasserre hierarchy for real polynomial optimization. We apply the approach to large-scale sections of the European high-voltage electricity transmission grid. Thanks to an algorithm for exploiting sparsity, instances with several thousand variables and constraints can be solved to global optimality.
Biography: Cédric Josz is currently pursuing a postdoctoral project under the supervision of Jean Bernard Lasserre in the Laboratory for Analysis and Architecture (LAAS CNRS) in Toulouse, France. His work is funded by a European Research Council Advanced Grant and deals with non-convexity in optimization. He received a PhD in applied mathematics from the University of Paris VI in 2016 in collaboration with the French transmission system operator (Rte) and the French Institute for Research in Computer Science and Automation (INRIA).

Talk Title: Increasing Battery Potential: Estimation & Control of Electrochemical Models
Series: CommNetS
Abstract: Batteries are ubiquitous. However, today's batteries are expensive, range-limited, power-restricted, die too quickly, and charge too slowly. Batteries are conservatively operated because their control systems treat the internal electrochemical dynamics as a black-box. Given real-time estimates of the electrochemical states, however, one can safely operate batteries near their physical limits, thus significantly enhancing performance beyond current state-of-art battery management systems. This talk reviews recent advancements in enhanced battery performance via estimation and control of PDE electrochemical models.
First, we review battery electrochemistry. Second, we discuss canonical state-of-charge (SOC), state-of-health (SOH), and other so-called SOx estimation algorithms. Third, we present recent theoretical results in state estimation and optimal control with PDE models. Finally, we close with exciting new opportunities for next-generation battery management systems.
Biography: Scott Moura is an Assistant Professor at the University of California, Berkeley in Civil & Environmental Engineering and Director of eCAL. He received the Ph.D. degree from the University of Michigan in 2011, the M.S. degree from the University of Michigan in 2008, and the B.S. degree from the UC Berkeley, in 2006 - all in Mechanical Engineering. He was a postdoctoral scholar at UC San Diego in the Cymer Center for Control Systems and Dynamics, and a visiting researcher in the Centre Automatique et Systemes at MINES ParisTech in Paris, France. He is a recipient of the O. Hugo Shuck Best Paper Award, Carol D. Soc Distinguished Graduate Student Mentoring Award, Hellman Faculty Fellows Award, UC Presidential Postdoctoral Fellowship, National Science Foundation Graduate Research Fellowship, University of Michigan Distinguished ProQuest Dissertation Honorable Mention, University of Michigan Rackham Merit Fellowship, and Distinguished Leadership Award. He has received multiple conference best paper awards, as an advisor & student. His research interests include control & estimation theory for PDEs, optimization, machine learning, batteries, electric vehicles, and the smart grid.
