主　　题：Large-scale renewable energy voltage source converter-based ultra-high voltage direct current(UHVDC) mid-and high-frequency resonance suppression measure 

摘      要：Mid-and high-frequency resonance(MHFR)is highly likely to occur at the sending end of voltage source con-verter-based ultra-high voltage direct current(VSC-UHVDC)for large-scale renewable energy *** is of great im-portance to investigate the resonance characteristics and the corresponding suppression ***,this paper intro-duces the overall control scheme of VSC-UHVDC for large-scale renewable energy ***,the impedance mod-els of VSC under grid-forming control with AC voltage coordi-nated control are *** mid-and high-frequency im-pedance characteristics of VSC-UHVDC are *** key factors affecting the impedance characteristics have been re-vealed,including the AC voltage control,the voltage feedfor-ward,the inner current loop,the positive-sequence and nega-tive-sequence independent control(PSNSIC),and the control *** MHFR characteristics at the sending-end system are analyzed in the whole operation process,including the black start and the normal power transmission *** integrat-ed control scheme is proposed to address the MHFR ***,extensive case studies are conducted on a planned VSC-UHVDC project to verify the theoretical analysis.
