Resumen

This paper attends to the modelling of power fluctuations of large offshore wind farms, concretely this paper focuses in the analysis of the spectral coherence models for the wind speed. So, firstly the current coherence models are analysed from the point of view of the Power Fluctuation. Then the paper shows the need of a new coherence model adapted to this frame i.e. to the characteristic length and height of nowadays wind farms and the characteristic time of the power fluctuation. This paper provides an adapted coherence model. That model has been developed using wind speed and power measurements from the 72 Wind Turbines and 2 of the meteorological masts from Nysted Offshore Wind Farm during 9 months.
