    • Optimal LQG Controller for Variable Speed Wind Turbine Based on Genetic Algorithms 

      Barrera-Cardenas, Rene Alexander; Molinas Cabrera, Maria Marta (Journal article; Peer reviewed, 2012)
      Linear Quadratic Gaussian (LQG) control methodology shows useful properties of good performance and robust-ness in controller design applied to wind turbine. Typically, in the design procedure LQG method is necessary to ...

    • Passive Filter Design and Offshore Wind Turbine Modelling for System Level Harmonic Studies 

      Brantsæter, Henrik; Kocewiak, Łukasz; Tedeschi, Elisabetta; Årdal, Atle Rygg (Peer reviewed; Journal article, 2015)
      This paper is aimed at creating a framework for harmonic studies of an offshore wind power plant by means of system level time domain simulations. Many modern wind turbine generators employ full-scale power electronic ...

    • 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. ...

    • Smooth Transition Between Controllers for Floating Wind Turbines 

      Lindeberg, Eivind; Svendsen, Harald Georg; Uhlen, Kjetil (Journal article; Peer reviewed, 2012)
      This paper presents a novel wind turbine control system which gives a smooth power output during transitions between different controllers. The paper presents an implementation of a control system designed for an offshore ...

    • Smoothing of Offshore Wind Power Variations with Norwegian Pumped Hydro: Case Study 

      Destro, Nicola; Korpås, Magnus; Sauterleute, Julian Friedrich (Peer reviewed; Journal article, 2016)
      The solar and wind energy production in the European countries has been growing in the last years and the need of energy storage too. One of the most competitive technologies already available for large-scale balancing is ...

    • The Assessment of Overvoltage Protection Within Energization of Offshore Wind Farms 

      Soloot, Amir Hayati; Høidalen, Hans Kristian; Gustavsen, Bjørn Alfred (Journal article; Peer reviewed, 2012)
      The beneficiary of Offshore Wind Farms (OWF) to land wind farms in the sense of more power productivity and land view disturbance leads to more investment and consideration. Nevertheless, the maintenance of OWFs is a ...
