Method and arrangement for responding to a grid event, such as fast under frequency combining demand response, inertial response and spinning reserve

摘要

A method for controlling a wind power plant in case of a frequency drop in a utility grid to which the wind turbines are connected is provided. The method includes combining demand response, inertial response and spinning reserve for given wind speeds in order for wind power plants to deliver fast aggregate under frequency response for a wide wind speed range with minimal recovery time and minimal production loss at each wind speed.

1. A method for controlling a wind turbine, when a frequency drop in a utility grid to which the wind turbine is connected exists, the method comprising:
increasing power extraction from a rotating rotor of the wind turbine; and simultaneously
decreasing a power demand of the wind turbine from a nominal power demand,wherein a net power output of the wind turbine to the utility grid is increased.
