The risk of resonances in the frequency range of several hertz to several hundred Hertz may occur in wind farms integration via MMC-HVDC. Stability of wind power integration via MMC-HVDC based on frequency-coupled impedance scanning method is analysed in this paper. First, a frequency-coupled impedance analysis method that is used to measure the sequence impedance models of wind power integration via MMC-HVDC is presented. Then, the network damping stability criterion and aggregated RLC circuit approach is applied for the quantitative assessment of potential resonance risk. Finally, impedance characteristic and stability assessment of doubly-fed induction generator-based wind farms integration via MMC-HVDC is analysed for the resonances in sub/super-synchronous frequency band, medium frequency band and high frequency band respectively.
