This animation explains why sometimes oscillations at the fundamental frequency are observed in the d-q variables: the dc offset in stationary reference frame will show up as the fundamental ac term in synchronous reference frame.
The Python code for this animation is in the Google Colab file: https://colab.research.google.com/dri...
