Classification: CPC H  F  Y | IPC F  H

Claim 14:
15. A wind turbine, comprising:
a tower;
a nacelle disposed on the tower and housing a generator;
a rotor extending from the generator and having a plurality of blades disposed on a distal end thereof;
a machine side converter;
a line side converter;
a DC link
a chopper electrically connected to an output of the machine side converter and an input of a grid side converter; and
a control system configured to perform an operation, comprising:
determine a virtual synchronous machine rotational speed and a virtual synchronous machine angle, where the virtual synchronous machine rotational speed is determined based on a combination of a feedback of a damping power, a power reference for a desired power output of the wind turbine, a grid power supplied by the wind turbine to a power grid and a chopper power dissipated by the chopper and an inertial integration model, where the virtual synchronous machine angle is determined based on an integration of the virtual synchronous machine rotational speed, and where the damping power is determined based on the virtual synchronous machine rotational speed.
