The progressive development of turbulence statistics and its impact on wind power predictability

This paper presents three aspects of turbulence assessment within the built environment. Firstly, an analysis of how turbulence is currently quantified is considered. The industry standard, TI (Turbulence Intensity) is compared with a proposed alternative metric described as TDf modelling (Turbulent Fourier Dimension). Secondly, the application of the turbulence assessment is considered with respect to how TI affects the productivity of small/micro wind turbines in complex environments though Gaussian distribution analysis. Finally, an extended discussion on current developments such as the concept of a turbulence rose and the ongoing development of statistical modelling is presented.
