Wind Energy

Bakgrund

The wind resource over sea is generally greater than over land, which makes offshore wind power attractive. Difficulties exist in more accurate assessment of the wind climate over sea due to factors such as how the dynamic wave field should be included in the calculations. Across inland seas such as the Baltic Sea the meteorological conditions also differ from open sea conditions due to proximity to land. This gives effects such as low level jets (LLJ) , which have a large impact on the wind resource as they can exist near hub height.

The models’ ability to capture these important phenomena over sea is still unclear. An improved understanding of these types of mesoscale weather systems and the models ability to correctly capture them will improve future offshore wind resource assessments and also short term offshore production used at the energy market.

Aims

The overall purpose is to improve the conditions for assessing wind resources for offshore wind farms for the inland Baltic Sea and evaluation/improvement of forecast models’ ability to calculate wind over sea

Approaches

In situ observations of wind speed up to several hundred meters height are scarce especially over ocean. We will hear utilize the existing data from the Baltic Sea. This data will be the foundation for the evaluation and improvement of the model simulations.
