This paper focuses on generic Type 4 wind turbine generators models, their applicability in modern HVDC connections and their capability to provide advanced ancillary services therefrom. A point-to-point HVDC offshore connection is considered. Issues concerning coordinated HVDC and wind farm control as well as the need of a communication link are discussed. Two possible control configurations are presented and compared. The first is based on a communication link transmitting the onshore frequency directly to the wind power plant, while the second makes use of a coordinated control scheme involving the HVDC converters- The performance against frequency disturbances of the two presented configurations is assessed and discussed by means of simulations.
