If you have a question about this talk, please contact Fei Teng. This talk has been canceled/deleted Renewable-based resources have been integrated into power systems at a very high pace the last decades. As a result, the net load, i.e., the difference of load demand and generation of renewable resources, is highly variable and uncertain. A method of mitigating the risks associated with uncertainty sources related to renewable-based generation is with the development of hybrid energy systems. The hybridisation of energy systems is useful especially when complementary resources are coupled, e.g., hydro and solar generation are nicely coupled. Hydroelectric power systems are fitting candidates since they have good ramping capability and energy storage possibility in form of hydro reservoirs. Energy storage adds substantial degrees of flexibility and “dispatchability” in a highly stochastic future power system. Optimising the dispatch of such a hybrid system is a non-convex, potentially large scale problem. In this talk, a computationally efficient, highly scalable solution, including convex relaxations will be presented. In addition, uncertainty in the net load and the inflows to the hydroelectric system will be considered to construct a robust short-term optimal dispatch framework for a hybrid hydro-solar system. The developed robust variant is intractable due to the infinite number of constraints. Using tools from robust optimisation, the resulting problem is reformulated in a tractable form that is amenable to existing numerical tools and is used to show that the computed dispatch is immunised against uncertainty. Bio: Dr Dimitra Apostolopoulou is a Lecturer at the Department of Electrical and Electronic Engineering at City University of London. Prior to her current appointment, she was a Postdoctoral Researcher in the Engineering Department and a Lecturer at Christ Church College at University of Oxford. Previously, she worked at the Smart Grid & Technology Department in Commonwealth Edison (ComEd) at Chicago – a unit of Exelon Corp. (Chicago, Illinois, U.S.) that provides service to approximately 3.8 million customers. She was awarded a Ph.D. and a M.S. in Electrical and Computer Engineering from University of Illinois at Urbana-Champaign in 2014 and 2011, respectively and her undergraduate degree in Electrical and Computer Engineering from National Technical University of Athens, Greece in 2009. Her research lies on the interface of power and energy systems, decision and control, economics and energy policy. This talk is part of the Control and Power Seminars series.
