11:30 - 13:00 Wakes: LiDAR measurements, layout optimization and modelling uncertainties
The focus of this session is on wind turbine wakes. Two studies deal with measurement of the wake wind field using LiDARs, and subsequently verifying them against reference instruments. One study deals with wind farm layout optimization in a complex terrain, where the wake wind field is generated using CFD tools. One study deals with providing a framework for evaluating wake models uncertainties, and subsequently their influence on the predicted wind turbine power in wakes.
- The importance of evaluating the uncertainty of the estimated wind speed in wakes using measurements from a Doppler LiDAR, with an example of how to do it under different atmospheric conditions
- How a 3D wake wind field looks like from LiDAR measurements, potentially paving the way for its subsequent use in wake tracking and model parameterization
- How CFD wake results in complex terrain can be combined with layout optimization techniques, potentially being applicable to wind farm design
- A framework for wind farm flow model validation, where it is demonstrated how uncertainties in input variables propagate into resulting uncertainties in predicted wind turbine power in wakes
