Optimization and Equilibrium Problems in Renewable Power Systems and Markets

Abstract This talk will focus on optimization and equilibrium problems in the energy sector. The transition to a sustainable energy system requires a redesign of traditional decision support to accommodate fluctuating renewable energy sources and the accompanying need for power system flexibility, e.g. through storage optimization and generation and transmission system expansion. A recent broadening of this research agenda is coordinated optimization across energy sectors, a critical element in achieving decarbonization. In combination, equilibrium modelling can appropriately account for the characteristics of liberalized markets, including misalignments of market player and social objectives, e.g. due to market imperfection. In addition to developing decision support for operation and investment, this may serve as a basis for energy policy assessment and design. The talk aims to bridge economic and technical aspects of energy modeling and optimization. 

Trine Krogh Boomsma is an Associate Professor in Operations Research (OR) at Department of Mathematical Sciences, University of Copenhagen. Her primary research focus has been on applications of OR to electricity systems, with emphasis on stochastic optimization and equilibrium modelling. Additional research interests encompass multi-objective optimization and shipping problems. Her publication record includes numerous papers published in internationally recognized journals. Academic experience further encompasses extensive teaching and supervision activities, departmental service as committee and board member, grant and project management, involvement in several assessment committees, conference organization, and the role of associate editor.

Technology and Policy Challenges to Decarbonize Electricity Systems

Abstract The electricity industry and policymakers are grappling with decarbonizing electricity systems. Decarbonization will yield significant changes in how electricity systems are planned and operated and will require policy and market-design reforms. This talk will survey these changes as well as the major challenge of achieving the final 10%-20% of decarbonization (relative to a business-as-usual benchmark).

Ramteen Sioshansi is a professor in Department of Engineering and Public Policy and Department of Electrical and Computer Engineering, director of Carnegie Mellon Electricity Industry Center, and a faculty affiliate of Wilton E. Scott Institute for Energy Innovation at Carnegie Mellon University and an adjunct professor in Department of Integrated Systems Engineering at The Ohio State University. His research focuses on the techno-economics of decarbonizing energy systems. He works also in energy policy and electricity-market design, especially as they pertain to energy decarbonization. He is an IEEE Fellow and served three two-year terms on Electricity Advisory Committee, a federal advisory committee to the U.S. energy secretary, and chaired its Energy Storage (Technologies) Subcommittee.

Modeling with Stochastic Programming

Abstract Much of the stochastic programming literature is on mathematics or algorithms, some is on principal models. But very few are on real use of the models. I discuss the problems that arise when trying to really use stochastic programming, and where I think we are (or should be) headed.

Stein W. Wallace is a Professor of Operational Research and leader of the Centre for Shipping and Logistics at NHH. He received his Dr. Scient degree in informatics from the University of Bergen in 1984. He has earlier held professorships at for example Lancaster University Management School, The Chinese University of Hong Kong, Molde University College and NTNU, as well as visiting positions at for example Business School of Sichuan University in Chengdu, IBM Watson Research in NY, Columbia University, ENP Grenoble and The University of Washington.

Wallace has published more than 110 papers in internationally leading journals such as Operations ResearchManagement ScienceProduction and Operations ManagementTransportation ScienceTransportation Research A, B and D and EMathematical Programming and INFORMS Journal on Computing. He is best known for his work in stochastic programming (in particular the two books Stochastic Programming (with Peter Kall from 1994) and Modeling with stochastic programming (with Alan King from 2012)), but also for work in logistics and energy systems. He has over 13000 citations.

He has been on numerous editorial boards, in particular INFORMS Journal on Computing (1990-2018). He founded the Norwegian OR Society and has held elected positions in The British OR Society as well as The Society for Transportation and Logistics in INFORMS and The Mathematical Programming Society.
