Abstract

In this work, the power oscillations during continuous operation of a whole wind farm and a single turbine are characterized for timescales in the range of minutes to fractions of seconds. A stochastic model is derived in time and frequency domains to link the overall behavior of a large number of wind turbines from the operation of a single turbine. A literature review on experimental data of Power Spectral Densities (PSD) and periodograms (averaged spectrum) of power output from wind turbines and wind farms are presented. The variability of PSD is also studied through spectrograms (joint time-frequency domain)
