    • Integrated Modelling Platform for Dynamic Performance Assessment of Floating Wind Turbines 

      Endegnanew, Atsede Gualu; Satertro, Kristian; Gjerde, Sverre Skalleberg; Svendsen, Harald Georg; Anaya-Lara, Olimpo; Tande, John Olav Giæver; Uhlen, Kjetil; Gjolmesli, Svein (Journal article; Peer reviewed, 2015)
      The paper presents an integrated modelling platform that can be used to assess the dynamic performance of an offshore wind turbine mounted on a spar-buoy type floater. Sub-models of generator and converter controllers and ...
    • Using Decentralized Control Techniques for Interaction Analysis in Hybrid AC/DC Grids 

      Endegnanew, Atsede Gualu; Kalemba, Lester; Uhlen, Kjetil (IEEE Power & Energy Society General Meeting;2018, Chapter; Peer reviewed, 2018)
      One of the ancillary services that can be provided by Multi-terminal Direct Current (MTDC) grid to connected ac grids is power oscillation damping (POD). However, using PODs at multiple terminals of an MTDC grid results ...
    • Wind farm voltage dip measurements 

      Marvik, Jorun Irene; Tande, John Olav Giæver; Uhlen, Kjetil (Journal article; Peer reviewed, 2014)
      This paper is based on continuous measurements of voltages and currents from three wind farms for a period of 1 year, and the focus is on voltage dips. The purpose is to get an overview of the characteristics and rate of ...
