Control systems of wind generators are usually designed neglecting the effect of the external grid (the impedance of the grid is much smaller than the impedance of the step-up transformers). Wind generator manufacturers are facing considerable challenges when connecting their machines to weak systems. A number of issues may arise. This paper classifies them and proposes a common approach to address them.
Keywords: Wind generation, weak systems, subsynchronous resonance, harmonic interaction, voltage stability, controller interaction.
