Wind Height Distribution Influence on Offshore Wind Farm Feasibility Study

In this paper the Monin-Obukhov theory, with the modifications induced by the Charnock model, is used for the description of the wind speed profile and its implications on the potential site productivity of an offshore wind farm. The estimated gross annual energy production has been obtained starting from field wind data measured at 10m height, and the different theories have been used to derive the wind data at 85 m height. The comparison of the different annual directional distribution of the wind speed has been made, and the relative implications on the power production of an offshore wind farm have been discussed.
