• An overview on formulations and optimization methods for the unit-based short-term hydro scheduling problem 

      Kong, Jiehong; Skjelbred, Hans Ivar; Fosso, Olav B (Journal article; Peer reviewed, 2019)
      The short-term hydro scheduling (STHS) problem aims at determining the optimal power generation schedules for either a single hydropower plant or an integrated system of cascaded watercourses during a time horizon from a ...
    • Dynamic incorporation of nonlinearity into MILP formulation for short-term hydro scheduling 

      Skjelbred, Hans Ivar; Kong, Jiehong; Fosso, Olav B (Journal article; Peer reviewed, 2019)
      Optimization tools are widely used for solving the short-term hydro scheduling (STHS) problem in a cascaded hydro system. In a mixed integer linear programming (MILP)-based formulation, the nonlinear and non-convex hydropower ...
    • Machine Learning for Hydropower Scheduling: State of the Art and Future Research Directions 

      Bordin, Chiara; Skjelbred, Hans Ivar; Kong, Jiehong; Yang, Zhirong (Peer reviewed; Journal article, 2020)
      This paper investigates and discusses the current and future role of machine learning (ML) within the hydropower sector. An overview of the main applications of ML in the field of hydropower operations is presented to show ...
    • Optimal Pricing of Production Changes in Cascaded River Systems with Limited Storage 

      Riddervold, Hans Ole; Skjelbred, Hans Ivar; Kong, Jiehong; Elvetun, Ole Løseth; Korpås, Magnus (Chapter, 2019)
      Optimization of hydroelectric power production is often executed for river systems consisting of several powerplants and reservoirs located in the same region. For hydropower stations located along the same river, the ...
    • 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 ...
    • Progressive hedging for stochastic programs with cross scenario inequality constraints 

      Aasgård, Ellen Krohn; Skjelbred, Hans Ivar (Journal article; Peer reviewed, 2019)
      In this paper, we show how progressive hedging may be used to solve stochastic programming problems that involve cross-scenario inequality constraints. In contrast, standard stochastic programs involve cross-scenario ...
    • Rolling Horizon Simulator for Evaluation of Bidding Strategies for Reservoir Hydro 

      Riddervold, Hans Ole; Aasgård, Ellen Krohn; Skjelbred, Hans Ivar; Naversen, Christian Øyn; Korpås, Magnus (Chapter, 2019)
      In this paper, a practical approach for benchmarking different bidding strategies towards the day-ahead market has been evaluated. A rolling horizon simulation framework is developed and closely integrated in the daily ...
    • Strategic Research Agenda of the EERA Joint Programme Hydropower 

      Aberle, Jochen; Avellan, Francois; Boes, Robert; Cavazzini, Giovanna; Perez Diaz, Juan I.; Doujak, Eduard; Finger, David Christian; Hendrick, Patrick; Heidenreich, Sara; Köhler, Berit; Lundström, Staffan; Riedelbauch, Stefan; Siemonsmeier, Marius; Schürhuber, Robert; Skjelbred, Hans Ivar; Storli, Pål-Tore Selbo (Research report, 2019)
      The launch of a new EERA Joint Programme on Hydropower is good news for energy system in Europe and beyond. The clean energy transition is necessary, demanding and accelerating. Hydropower in Europe and worldwide represents ...
