Abstract (EN): Power quality requirements related to renewable energy systems and distributed generation are becoming more restrictive, especially in the total harmonic distortion of the injected grid current. The doubly-fed induction generator is particularly appropriate to be used in wind power generation systems. However, in weak grids its stator connection to unbalanced or distorted voltages not only causes harmonic currents in the stator but also imposes low frequency and high amplitude rotor current harmonics. Also, the grid-side converter must deal with the same voltage conditions. The paper addresses the first issue presenting a voltage harmonics controller in the d-q reference frame to be included in the high dynamics rotor current controller Simulation and experimental results demonstrate the performance of the proposed controller imposing a sinusoidal input current.
