Abstract:
A variable speed wind turbine is arranged to provide additional electrical power to counteract non-periodic disturbances in an electrical grid. A controller monitors events indicating a need to increase the electrical output power from the wind turbine to the electrical grid. The controller is arranged to control the wind turbine as follows: after an indicating event has been detected, the wind turbine enters an overproduction period in which the electrical output power is increased, wherein the additional electrical output power is taken from kinetic energy stored in the rotor and without changing the operation of the wind turbine to a more efficient working point. When the rotational speed of the rotor reaches a minimum value, the wind turbine enters a recovery period to re-accelerate the rotor to the nominal rotational speed while further contributing to the stability of the electrical grid by outputting at least a predetermined minimum electrical power.

Claim (Index 1):
A wind turbine for connection to an electrical grid, the wind turbine comprising:\n a rotor with blades coupled to an electrical generator; and a controller configured to:\n increase, in response to an event, an electrical output power from the wind turbine for a duration of an overproduction period using kinetic energy stored in the rotor thereby decreasing a rotational speed of the rotor, and \n after increasing the electrical output power and before the rotational speed of the rotor reaches a predetermined minimum value, accelerate the rotor for a duration of a recovery period to a previous rotational speed while outputting at least a predetermined minimum electrical power to the electrical grid.
