Abstract: A wind farm side voltage source converter (32; 94) comprises a DC terminal (40) for connection to a DC transmission link (38), an AC terminal (42) for connection to a wind farm (44) that includes at least one wind turbine (46), and a main controller (10; 20; 96). The main controller (10; 20; 96) is configured to modify an active power demand (P demand ) of the voltage source converter (32; 94) which is received from a higher level controller by introducing an artificial inertia factor and/or in response to a measured DC voltage (V dc_msr ) at the DC terminal (40).
