Harmonic Transfers for Quantifying Propagation of Harmonics in Wind Power Plants [PDF]
Energies, 2021 In this paper, primary and secondary emissions in wind power plants are studied by using transfer admittance and current transfer functions between turbines and the public grid. The use of such transfer functions allows harmonic propagation studies without knowledge of the emission from individual turbines or the background voltage distortion.
