The installed offshore wind energy capacity in Europe has been increasing rapidly over the past years, this trend is expected to continue thanks to the European green deal. In order to meet the future energy demand, new wind energy solutions such as increasing wind turbine size but also floating structures are being developed. This means that stability phenomena and their effects on wind turbine fatigue and energy yield are becoming increasingly important.
The aim of this thesis project is to define and quantify the applications and limitations of the Dutch Offshore Wind Atlas for wind energy purposes by using it to calculate the energy yield and fatigue damage of two reference wind turbines at multiple locations in the North Sea, with special attention for atmospheric stability. Atmospheric stability is quantified using the shear exponent, Obukhov length and potential temperature profile. For the energy yield and fatigue calculations, a comparison is made between DOWA hourly data, 10-minute LES runs and site measurements as well as a comparison between locations across the North Sea. Additionally, some relevant parameters for wind farm design such as weather windows and dominant wind direction are analysed.
The results show that for certain wind energy applications, the DOWA data performs relatively well, but several limitations were found as well.
