This paper presents control strategies for multi-terminal HVDC systems to provide primary frequency support to connected AC networks via coordinated DC voltage manipulation. Inertia response from DC connected large offshore wind farms can also be incorporated without telecommunication based on the detection of DC voltage derivation. Simulation studies ba sed on a 3-terminal HVDC system connecting one large wind farm and two separate AC networks validate the operation of the system during frequency events.
