Analyse of measurements on wind turbine arrays. Vol. 2

The aim was to discover a suitable model for the prognosis of the power output of wind turbine arrays. Models should show the output over a chosen period of time, a linear transferable function model for output with wind velocity as the variable, a combination of the time period model for the wind velocity and the output curve, and a combination of wind velocity prognoses from VTC-Karup and output curve. The first three models are different from the fourth as they are based on the actual development of output and/or wind velocity whereas the fourth model is based on professional meteorologists' prognosis of the wind speeds. A number of output curve models are discussed in detail in order to determine which is the most satisfactory. (AB)
