A 2050 perspective on the role for carbon capture and storage in the European power system and industry sector
Holz, Franziska; Scherwath, Tim; Crespo del Granado, Pedro; Skar, Christian; Olmos, Luis; Ploussard, Quentin; Ramos, Andrés; Herbst, Andrea (Peer reviewed; Journal article, 2021)Carbon Capture and Storage (CCS) might be a central technology to reach the decarbonisation goals of the European energy system. However, CCS deployment faces multiple economic, technological, and infrastructure challenges. ... -
A Profit Maximisation Model for Operation of a Tidal Lagoon Power Plant - Determination of Optimal Operational Schedule and Potential Value Added by Integration in a High Intermittent Power System
Schaffer, Linn Emelie; Næss, Trine Rollefsen (Master thesis, 2016)A stochastic profit maximisation model for operation of a tidal lagoon power plant including production head effects, power market prices and start-up costs is developed. The model is formulated as a two-stage stochastic ... -
DSL and Engine for Pervasive Treasure Hunt Games
Hosseinpoor, Habibollah; Skar, Christian (Master thesis, 2012)The purpose of this master thesis was to eliminate the technical barrier for creating pervasive games. In order to achieve this a domain-specific language (DSL) was made along with an engine to interpret the DSL scripts. ... -
EMPIRE: An open-source model based on multi-horizon programming for energy transition analyses
Backe, Stian; Skar, Christian; Crespo del Granado, Pedro; Turgut, Ozgu; Tomasgard, Asgeir (Peer reviewed; Journal article, 2021)Energy and power system models represent important insights on the technical operations of energy technologies that supply the energy consumption in time steps with hourly resolution. This paper presents the European Model ... -
European energy transition under limited onshore wind and transmission expansion and the role of technology innovation
Hammersvik, Sylvia B. (Master thesis, 2021)I lys av Parisavtalen, så er det et kritisk behov for å redusere klimagassutslippene for å holde den globale oppvarmingen under to grader. For de Europeiske landene så er en gradvis overgang fra fossile- til fornybare ... -
Implementing Hydropower Scheduling in a European Expansion Planning Model
Brovold, Sondre Heen (Master thesis, 2014)This Master s thesis proposes a method for implementing an enhanced hydropower planning formulation in a long-term expansion planning model. The motivation for this work is the important role that hydropower plays in a ... -
Implementing Hydropower Scheduling in a European Expansion Planning Model
Brovold, Sondre; Skar, Christian; Fosso, Olav B (Journal article; Peer reviewed, 2014)A method for implementing an enhanced hydropower planning formulation in a long-term expansion planning model is proposed. The methodological framework involves assigning hydropower generation a marginal cost through water ... -
Investments in the EU Power System: A Stress Test Analysis on the Effectiveness of Decarbonisation Policies
Crespo del Granado, Pedro; Skar, Christian; Doukas, Haris; Trachanas, Georgios P. (Chapter; Peer reviewed, 2019)Ambitious emission reduction targets are challenging the status quo on designing effective strategies for electricity generation portfolios. In this chapter, we consider the role of low-carbon technologies and determine ... -
Linking Global and Regional Energy Strategies (LinkS)
Bakken, Bjørn Harald; Dalen, Kari; Graabak, Ingeborg; Knudsen, Jørgen Kjetil; Ruud, Audun; Warland, Leif; Wolfgang, Ove; Doorman, Gerard L.; Skar, Christian; Tomasgard, Asgeir; Valdes, Gerardo Alfredo Perez (SINTEF Energi. Rapport;, Research report, 2014)The LinkS project was designed to analyse how global long-term strategies can be used as guidelines for the development of energy supply and technology deployment in regional energy systems. In order to produce recommendations ... -
Modeling low emission scenarios for the European power sector
Skar, Christian (Doctoral thesis at NTNU;2016:198, Doctoral thesis, 2016)The long-term ambition for the European power sector is to almost completely decarbonize generation of electricity. There are potentially many ways of achieving this, however, assessing an optimal transition to a low-carbon ... -
Simplification algorithms for large-scale power system transmission grids
Kruijer, Tomas (Master thesis, 2015)The simulation of large-scale power system models including transmission grid representations is limited by available computation power and time. Therefore, the reduction of transmission grid models is of paramount importance. ... -
Strategic Hydro Reservoir Modeling with Intermittent Renewables in a Long-Term Capacity Investment Model for the European Power System
Laupsa, Hans; Holt, Mattis (Master thesis, 2018)An enhanced hydropower planning framework is introduced in a revamped formulation of the long-term European power system expansion model EMPIRE, making it a hybrid model featuring a combination between the traditional ... -
The Expectation Propagation Algorithm for use in Approximate Bayesian Analysis of Latent Gaussian Models
Skar, Christian (Master thesis, 2010)Analyzing latent Gaussian models by using approximate Bayesian inference methods has proven to be a fast and accurate alternative to running time consuming Markov chain Monte Carlo simulations. A crucial part of these ...
