Power curves for wind energy converters (WECs) provide an essential relation between wind speed and electrical power output. The current industry standard IEC 61400-12-1 defines a unified procedure for the derivation of power curves. Recently, a novel method has been proposed to obtain power curves for WECs from high frequency data of power output P(t) and wind speed measurements u(t), the dynamical or Langevin power curve P L (u). This approach models the short-time dynamics of the wind power conversion as a relaxation process, driven by the turbulent wind. In this contribution, we show the independence of the Langevin approach from the turbulence characteristics of the inflow.
