Complementarity-constrained predictive control for efficient gas-balanced hybrid power systems
Hoang, Kiet Tuan; Knudsen, Brage Rugstad; Imsland, Lars Struen (Peer reviewed; Journal article, 2024)Controlling gas turbines (GTs) efficiently is vital as GTs are used to balance power in onshore/offshore hybrid power systems with variable renewable energy and energy storage. However, predictive control of GTs is non-trivial ... -
Constrained adaptive sampling for domain reduction in surrogate model generation: Applications to hydrogen production
Straus, Julian; Ouassou, Jabir Ali; Knudsen, Brage Rugstad; Anantharaman, Rahul (Peer reviewed; Journal article, 2021)We propose a new approach for sampling domain reduction for efficient surrogate model generation. Currently, the standard procedure is to use box constraints for the independent variables when sampling the exact simulator. ... -
Decarbonizing integrated chlor-alkali and vinyl chloride monomer production: Reducing the cost with industrial flexibility
Foslie, Sverre Stefanussen; Straus, Julian; Knudsen, Brage Rugstad; Korpås, Magnus (Peer reviewed; Journal article, 2023)Industrial demand response will become increasingly important in power grids with high shares of variable renewables, yet the existing knowledge on how the industrial electricity demand and flexibility will change with the ... -

Hierarchical nonlinear model predictive control of offshore hybrid power systems
Hoang, Kiet Tuan; Knudsen, Brage Rugstad; Imsland, Lars Struen (Peer reviewed; Journal article, 2022)This paper presents an approach for controlling ofshore hybrid power systems consisting of gas turbines, offshore wind, and batteries for satisfying an exogenous power demand. A hierarchical controller is developed comprising ... -
Hybrid Versus Radial Offshore Wind Connections: Power Grid Investments in the North Sea
Sævareid, Erik; Durakovic, Goran; Knudsen, Brage Rugstad; Straus, Julian; Tomasgard, Asgeir (Chapter; Peer reviewed, 2022)To enable offshore wind in the North Sea to take a key, rapid role in the European energy transition, massive grid expansions and investments are required. We consider the impact of such grid expansion in the North Sea on ... -
