Coordination and control in next generation energy systems

Professor John Lygeros, ETH Zurich

Modern energy systems involve a large number of agents (for example, the buildings in a district) each with local decision making capabilities, that interact through their common use of shared resources (for example, the energy conversion devices housed in a shared "energy hub"). The mutual constraints imposed by the shared resources require that the actions of the agents are coordinated. This can be accomplished through the exchange of information about global considerations of the system, provided, for example, by a central aggregator who can impose prices on certain actions, or mutual constraints among the agents. Since the local decision making of each agent typically also involves a local cost and local constraints, the question that arises is what type of information exchange ensures that the decisions of the players converge to a sensible global fixed point. In many cases the process is further complicated by the presence of uncertainty, for example about the weather, hence energy demand and renewable generation; in such cases, the decisions of the agents not only have to be coordinated with their peers, but also be robust against this uncertainty. In this talk we will discuss how such questions can be addressed using tools from distributed optimisation, robust optimisation, and game theory. The discussion will be motivated by applications to energy management in districts and demand response in electricity grids.

Biography

John Lygeros completed a B.Eng. degree in electrical engineering in 1990 and an M.Sc. degree in Systems Control in 1991, both at Imperial College of Science Technology and Medicine, London, U.K.. In 1996 he obtained a Ph.D. degree from the Electrical Engineering and Computer Sciences Department, University of California, Berkeley. During the period 1996-2000 he held a series of research appointments at the National Automated Highway Systems Consortium, Berkeley, the Laboratory for Computer Science, M.I.T., and the Electrical Engineering and Computer Sciences Department at U.C. Berkeley. Between 2000 and 2003 he was a University Lecturer at the Department of Engineering, University of Cambridge, U.K., and a Fellow of Churchill College. Between 2003 and 2006 he was an Assistant Professor at the Department of Electrical and Computer Engineering, University of Patras, Greece. In July 2006 he joined the Automatic Control Laboratory at ETH Zurich, first as an Associate Professor, and since January 2010 as a Full Professor; he is currently serving as the Head of the laboratory. His research interests include modelling, analysis, and control of hierarchical, hybrid, and stochastic systems, with applications to biochemical networks, automated highway systems, air traffic management, energy systems, and camera networks. John Lygeros is a Fellow of the IEEE, and a member of the IET and the Technical Chamber of Greece; since 2013 he is serving as the Treasurer of the International Federation of Automatic Control.
