Annual impact of wind-farm gravity waves on the Belgian-Dutch offshore wind-farm cluster

While research on wind-farm-atmospheric boundary layer interaction has primarily focused on local effects inside and above the farm, recent studies found that wind farms may affect the wind conditions several kilometres upstream of the farm via the excitation of atmospheric gravity waves. Such non-local effects can have strong implications for the wind-farm energy extraction but are currently overlooked in wind-farm design and operation and control strategies. In the present study, we employ a fast wind-farm boundary-layer model in combination with ERA5 reanalysis data to assess the potential... Mehr ...
