    Title: Approximations and Relaxations of Power Flow Equations

    Abstract: The design, control, and operation of the power grid, probably the largest and most expansive system ever engineered, require the solving of optimization problems over the steady-state power flow equations. The resulting mixed nonconvex programs are often computationally challenging and increasingly so with the increased stochasticity in generation and load.This talk presents a number of advances in approximating and relaxing the power flow equations to address emerging applications in power systems, including large-scale power restoration after blackouts, the design of resilient networks, and the integration of renewable generation. Extensive computational results demonstrate some of the benefits of the proposed techniques.

    Biography: Van Hentenryck is the leader of the Optimization Research Group (about 60 people) at NICTA, the Australian Center of Excellence for ICT Research. He also holds the Strategic Chair in Data Intensive Computing at the Australia National University. He is the recipient of two Honorary degrees, the 2002 INFORMS ICS Award for research excellence at the intersection of operations research and computer science, the 2006 ACP Award for research excellence in constraint programming, and the 2010-2011 Philip J. Bray Award for Excellence in Undergraduate Teaching at Brown University. He is a 2013 IFORS distinguished lecturer and a fellow of the Association for the Advancement of Artificial Intelligence. Van Hentenryck is the author of five MIT Press books and has developed a number of innovative optimization systems that are widely used in academia and industry. He also teaches a massively open online course in Discrete Optimization with Coursera.
