Abstract:Abstract. We propose that considering mesoscale wind direction changes in the computation of wind farm cluster wakes could reduce the uncertainty of engineering wake modelling tools. The relevance of mesoscale wind direction changes is investigated using a wind climatology of the German Bight area covering 30 years, derived from the New European Wind Atlas (NEWA). Furthermore, we present a new solution for engineering modelling tools that accounts for the effect of such changes on the propagation of cluster wa… Show more
“…As a next step, our method can be used to further develop and evaluate the representation of dynamic wind direction e ects on power production in engineering wake models. Recently, von Brandis et al [251] incorporated mesoscale background fields into the Fraunhofer IWES wind farm and wake modeling software Farm Layout Program in Python (flappy). Their study highlights the importance of considering wind direction changes in the modeling of wind farms, especially if multiple wind farms within close proximity of each other are considered [251].…”

“…In addition to the LES study of wind farm wakes presented in this thesis, other mesoscale flow phenomena have to be taken into account when studying wind farm wakes. For example, von Brandis et al [251] discovered that the mesoscale wind direction can change by more than 7 ¶ when considering distances of 5-100 km. These wind direction changes can have a significant impact on the interaction between wind farms.…”
