Wind Power in Forest II - Forestwind
Research Project , 2014 – 2017

The project aims at a better assessment of how a wind farm in forest produces and what loads occur. Over forest, there exists a larger vertical wind shear and turbulence compared to places without forest. This leads to reduced production but the uncertainty is large. Measurements at each individual wind turbine location are too expensive. Therefore, one must use models to estimate the energy production. The models' uncertainty over forest, however, is much greater than over places without forest. Forest effects on the wind resource, turbulence and loads are studied. Existing models for wind resource and load calculation are further developed. An LES-model is coupled to a mesoscale model for a more detailed description of turbulence over forest. Production data from existing wind farms in forests is analysed along with meteorological data. Additional wind and turbulence measurements are made with a min. 180 m high mast to gain further knowledge on the effect of forest on wind turbines.
