Room: Hall G2
Advanced modelling methods are now standard in wind estimating modelling of annual energy production (AEP). In this session, speakers will present round robin tests of models for spatial variability of wind resource on projects using different modelling approaches. We will look at the consequences of including atmospheric stability in the calculation of AEP offshore and how you can measure wind profiles at heights of 100-200 metres by using LIDARs with emphasis on charactering extreme shear situations such as low-level jets causing extreme loads. Finally, we will hear about the variability of turbulence intensities measured offshore.

Learning objectives
- Understand the different methods for modelling the spatial variability of wind resource at the project scale and the errors based on the different modelling approaches;
- How to incorporate stability in the AEP modelling in offshore wind farms;
- Understand the effect of using high resolution modelled wind climatologies combined with advanced boundary modelling on the estimation of the tall winds at 100-200 metres;
- How to characterise and define the extreme events such as low-level jets that can cause fatigue loads in a wind farm;
- Understand the variability of the turbulence intensities offshore measured from multiple measurement towers.
