Grid-forming functional requirements for HVDC converter stations and DC
The onshore HVDC converter station can get power supply from its DC-side. Another example is, for a remote-end HVDC converter station in GFM control or V/f control, it is the only voltage source in the offshore AC network transferring power from GFL PPMs to the DC circuit. The definition can also apply to a DC-connected PPM if it is in GFM control.
