• Assessment of wind conditions at a fjord inlet by complementary use of sonic anemometers and lidars 

      Jakobsen, Jasna Bogunovic; Cheynet, Etienne; Snæbjörnsson, Jonas Thor; Mikkelsen, Torben; Sjøholm, Mikael; Angelou, Nicolas; Hansen, Per; Mann, Jakob; Svardal, Benny; Kumer, Valerie-Marie; Reuder, Joachim (Journal article; Peer reviewed, 2015)
      Wind velocity measurement devices based on the remote optical sensing, lidars, are extensively applied in wind energy research and wind farm operation. The present paper demonstrates the relevance and potential of lidar ...
    • Offshore wind turbine wake characteristics using scanning doppler lidar 

      Krishnamurthy, Raghavendra; Reuder, Joachim; Svardal, Benny; Fernando, Harindra Joseph S.; Jakobsen, Jasna Bogunovic (Journal article; Peer reviewed, 2017-10)
      Within an offshore wind park, wind flow characteristics are quite complex and govern both the energy production and the structural wind turbine response. An experimental study focussed on assessing the spatial variability ...
    • Spectral characteristics of surface-layer turbulence in the North Sea 

      Cheynet, Etienne; Jakobsen, Jasna Bogunovic; Obhrai, Charlotte (Journal article, 2017-10)
      According to IEC 61400-1 and IEC 61400-3 standards, the wind load on the rotor-nacelle assembly of offshore wind turbines should be estimated from the Kaimal or Mann spectral models, unless site-specific full-scale ...
    • Wave Influenced Wind and the Effect on Offshore Wind Turbine Performance 

      Kalvig, Siri M.; Manger, Eirik; Hjertager, Bjørn H; Jakobsen, Jasna Bogunovic (Journal article; Peer reviewed, 2014)
      In this paper the effect of wave influenced wind on offshore wind turbines is studied numerically. The wave is seen as a dynamical roughness that influences the wind flow and hence the wind turbine performance. An actuator ...
    • Wind coherence measurement by a single pulsed Doppler wind lidar 

      Kumer, Valerie-Marie; Cheynet, Etienne; Jakobsen, Jasna Bogunovic; Svardal, Benny; Reuder, Joachim (Journal article; Peer reviewed, 2016)
      A single pulsed Doppler wind lidar, deployed at the FINO1 platform in the North Sea, has been used to monitor the lateral and vertical coherence of the along-wind component. To maximize the sampling frequency of the ...
