Description
Recent research has pointed out that wind farms can interact with the atmosphere at scales much larger than the turbine size. Although these large-scale effects are significant, they cannot be captured by the widely used engineering wake models. To bridge this gap, Allaerts & Meyers [1] developed an Atmospheric Perturbation Model (APM) that accounts for both turbine-scale and mesoscale effects on power predictions. The original model represents the atmospheric boundary layer as two sub-layers topped by the free atmosphere. This work aims to generalize the APM to a user-defined number of sub-layers, and to inform a simple physics-based procedure to define them. Preliminary results have shown that the improved model allows to study a wider range of atmospheric conditions. The current focus is placed on testing the performance of the model for realistic conditions provided by RMI (ECMWF data of the Belgian offshore zone).
