Sub-synchronous oscillations with type 3 wind turbines and MMC-HVDC

Sub-synchronous oscillations is an undesirable phenomenon in power systems. It is associated with the energy exchange between different elements of the system. Power electronics-based devices, such as windfarms and AC/DC converters are also prone to such oscillations. In this presentation, a case of sub-synchronous oscillations between type 3 wind turbines and MMC-based HVDC transmission is demonstrated and analyzed using EMTP.
