    • Accounting for reserve capacity activation when scheduling a hydropower dominated system 

      Naversen, Christian Øyn; Farahmand, Hossein; Helseth, Arild (Journal article; Peer reviewed, 2020)
      As the penetration of variable renewable power generation increases in power systems around the world, system security is challenged. It is crucial to coordinate the available flexible generating resources, such as hydropower, ...

    • Continuous Hydrothermal Flexibility Coordination Under Wind Power Uncertainty 

      Naversen, Christian Øyn; Parvania, Masood; Helseth, Arild; Farahmand, Hossein (Peer reviewed; Journal article, 2022)
      This paper develops a stochastic continuous-time optimization model for coordinating the operation of flexibility in a hybrid hydro-thermal-wind power system. The developed model gives insight for investigating the short-term ...

    • Continuous-time scheduling of a hydrothermal system with integration of offshore wind power 

      Øvstebø, Mari Lund; Naversen, Christian Øyn; Helseth, Arild; Farahmand, Hossein (Chapter, 2020)
      In this work, a continuous-time unit commitment formulation of a hydrothermal system with integration of offshore wind power is used to model the North European system operation. The cost of covering the structural imbalances ...

    • Flow-Based Market Coupling in Short-Term Hydro-Thermal Scheduling 

      Meberg, Torbjørn Røed (Master thesis, 2019)
      Flyten av kraft i det nordiske kraftsystemet er under endring, der det er en økning i produksjon fra fornybare energikilder i tillegg til en elektrifisering av ulike deler av industrisektoren, som forandrer sammensetningen ...

    • Fundamental Multi-Product Price Forecasting in Power Markets 

      Jaehnert, Stefan; Helseth, Arild; Naversen, Christian Øyn (SINTEF Rapport;, Research report, 2019)
      This report has been prepared in the first phase of the project 'Pricing Balancing Services in the Future Nordic Power Market1, and its purpose is two-fold. First, a review on expected future trends in European power markets ...

    • Hydrothermal scheduling in the continuous-time framework 

      Naversen, Christian Øyn; Helseth, Arild; Li, Bosong; Parvania, Masood; Farahmand, Hossein; Catalao, João P.S. (Peer reviewed; Journal article, 2020)
      Continuous-time optimization models have successfully been used to capture the impact of ramping limitations in power systems. In this paper, the continuous-time framework is adapted to model flexible hydropower resources ...

    • Modelling Approaches for Hydro-Dominated System Balancing 

      Naversen, Christian Øyn (Doctoral theses at NTNU;2021:8, Doctoral thesis, 2021)
      The generation mix in many power systems across the world is rapidly shifting towards higher degrees of variable renewable power generation. Maintaining the continuous power balance of the system under higher levels of ...

    • Multi-Market Price Forecasting in Hydro-Thermal Power Systems 

      Helseth, Arild; Haugen, Mari; Jaehnert, Stefan; Mo, Birger; Farahmand, Hossein; Naversen, Christian Øyn (Chapter, 2018)
      This paper presents a framework for price forecasting in hydro-thermal power systems. The framework consists of a long-term strategic and a short-term operational model. The strategic model provides the end-of-horizon ...

    • Operating a Battery in a Hydropower-Dominated System to Balance Net Load Deviations 

      Naversen, Christian Øyn; Bjarghov, Sigurd; Helseth, Arild (Chapter, 2019)
      Decreasing costs of battery storage technologies make them a viable option for providing flexibility in power systems. In this paper, we study the operations of a battery in combination with cascaded hydropower in a system ...

    • 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 ...

    • The Impact of Offshore Wind Power Variations on Continuous-time Scheduling of a Hydrothermal System 

      Øvstebø, Mari Lund (Master thesis, 2020)
      Som en del av klimapolitikken, forventes et betydelig omfang av offshore vindkraft å bli integrert i det nordeuropeiske kraftsystemet de kommende årene. Den varierende og i stor grad uforutsigbare kraftproduksjonen fra ...
