IEA-Wind Task 31 WAKEBENCH 2 (2015-2018)

Verification, Validation and Uncertainty Quantification (VV&UQ) of wind farm flow models. The purpose of the project is to improve wind farm modeling techniques and provide a forum for industrial, governmental and academic partners to develop, evaluate and improve wind farm models. While Task 31 Phase 1 was limited to the wind farm (microscale) scale, Phase 2 will extend the scope to mesoscale and near-wake modeling in order to cover all the relevant atmospheric scales related to wind power meteorology. This will allow a more comprehensive approach to the wind farm integrated design process, facilitating the exchange of knowledge among various research communities: meteorologists, resource/site wind engineers and wind farm/rotor aerodynamicists. The focus will still be placed on wind resource assessment, site suitability and wind farm design but allowing for a larger variety of modeling approaches. Some benchmarks will also be explored in finer detail to better quantify the uncertainty of a range of models for different phenomena.
