The uncertainty affecting wind resources has deep economic and technical consequences on the design, planning and operation of power systems. For this reason, long wind speed time series are typically necessary for planning and integration studies of this generation resource. Unfortunately, wind speed records of very limited length are often the only available wind information at the site of interest, which are typically insufficient for performing many studies. In this work, an algorithm based on spectral representation for generating synthetic wind speed time series in high resolution is presented. The algorithm exploits the limited available wind information and accurately replicates the statistical and the stochastic dynamics feature of wind observations. The modeling approach is non-parametric and therefore it can be applied to any wind site. Statistical tests indicate the simulated wind speeds can be further used with confidence in the framework of power system studies.
