• A branch-and-bound method for discretely-constrained mathematical programs with equilibrium constraints 

      Shim, Yohan; Fodstad, Marte; Gabriel, Steven; Tomasgard, Asgeir (Journal article; Peer reviewed, 2013)
      We present a branch-and-bound algorithm for discretely-constrained mathematical programs with equilibrium constraints (DC-MPEC). This is a class of bilevel programs with an integer program in the upper-level and a ...
    • Coordinated optimization of weekly reserve, day-ahead and balancing energy trade in hydropower 

      Fodstad, Marte; Grytli, Eirik Schou; Korpås, Magnus (Journal article; Peer reviewed, 2017)
      We present a model for optimal trade in a weekly power reserve market under day-ahead and balancing market price uncertainty. The model takes the perspective of a price-taking hydropower producer and a case study for the ...
    • Investments in the LNG Value Chain: A Multistage Stochastic Optimization Model focusing on Floating Liquefaction Units 

      Røstad, Lars Dybsjord; Erichsen, Jeanette Christine (Master thesis, 2012)
      In this thesis, we have developed a strategic optimization model of investments in infrastructure in the LNG value chain. The focus is on floating LNG production units: when they are a viable solution and what value they ...
    • Market Power in Hydro-Thermal Systems with Marginal Cost Bidding 

      Löschenbrand, Markus; Korpås, Magnus; Fodstad, Marte (Chapter, 2018)
      Traditionally, electricity markets have been designed with the intention of disabling producer side market power or prohibiting exercising it. Nonetheless it can be assumed that players participating in pool markets and ...
    • Multi-horizon stochastic programming 

      Kaut, Michal; Midthun, Kjetil Trovik; Werner, Adrian; Tomasgard, Asgeir; Hellemo, Lars; Fodstad, Marte (Journal article; Peer reviewed, 2014)
      Infrastructure-planning models are challenging because of their combination of different time scales: while planning and building the infrastructure involves strategic decisions with time horizons of many years, one needs ...
    • Optimal Bidding Strategy in the Reserve Capacity Market 

      Grytli, Eirik Schou (Master thesis, 2016)
      Good balancing services is a prerequisite for a well-functioning power market. Additionally to the day-Ahead market (DA) for electricity, there is a balancing market (BM) which provides the necessary buffers to handle short ...
    • Optimization Models and Algorithms for the Natural Gas Supply Chain 

      Fodstad, Marte (Doktoravhandlinger ved NTNU, 1503-8181; 2013:276, Doctoral thesis, 2013)
      Sammendrag Denne PhD-avhandlinga består av sju artikler om operasjonsanalytiske modeller og algorit- mer for forsyningskjeden for naturgass. Fokus er på oppstrømsdelen av forsyningskjeden, fra produksjon til salg i ...
    • Optimizing day-ahead bid curves in hydropower production 

      Aasgård, Ellen Krohn; Naversen, Christian Øyn; Fodstad, Marte; Skjelbred, Hans Ivar (Journal article; Peer reviewed, 2017)
      In deregulated electricity markets, hydropower producers must bid their production into the day-ahead market. For price-taking producers, it is optimal to offer energy according to marginal costs, which for hydropower are ...
    • Profitability of a Hydro Power Producer Bidding in Multiple Power Markets 

      Rasmussen, Caroline; Hansen, Jakob Boye; Korpås, Magnus; Fodstad, Marte (Peer reviewed; Journal article, 2016)
      The production scheduling of a hydro power producer exposed to the day-ahead, balancing and capacity market is examined to find what profit the producer may achieve by strategically bid in the above mentioned markets. ...
    • The Portfolio Perspective in Electricity Generation and Market Operations 

      Fleten, Stein-Erik; Midthun, Kjetil Trovik; Bjørkvoll, Thor; Werner, Adrian; Fodstad, Marte (Chapter, 2018)
      Selecting portfolios of electricity production assets, energy sources and market participation strategies facilitates usage and management of complementary resources. It helps also power producers to address uncertainties ...
    • Veikart for energi i Norge mot 2050 

      Schäffer, Linn Emelie; Rosenberg, Eva; Pisciella, Paolo; Damman, Sigrid; Espegren, Kari Aamodt; Fodstad, Marte; Graabak, Ingeborg; Perez-Valdes, Gerardo Alfredo; Sandberg, Eli; Johansen, Ulf; Seljom, Pernille Merethe Sire; Tomasgard, Asgeir (SINTEF Rapport;, Research report, 2020)
