This paper presents a wind model, which has been developed for studies of the dynamic interaction between wind farms and the power system to which they are connected. The wind model is based on a power spectral description of the turbulence, which includes the coherence between wind speeds at different wind turbines in a wind farm, together with the effect of rotational sampling of the wind turbine blades in the rotors of the individual wind turbines. Both the spatial variations of the turbulence and the shadows behind the wind turbine towers are included in the model for rotational sampling. The model is verified using measured wind speeds and power fluctuations from wind turbines. (C) 2002 Elsevier Science Ltd. All rights reserved.
