Sub-Synchronous Oscillation Characteristics and Analysis of Direct-Drive Wind Farms With VSC-HVDC Systems

IEEE Transactions on Sustainable Energy, 2021
Field experiences have shown that sub-synchronous oscillations (SSOs) can occur in direct-drive wind farms with VSC-HVDC (DDWFV) systems. In light of this, a dynamic mathematical model of the DDWFV is established in this paper.
