1. A method, comprising:
operating a wind turbine in a spinning reserve mode to provide a spinning reserve, the spinning reserve being an extra power generating capacity of the wind turbine that is available by increasing a power output of the wind turbine;
calculating an available power of the wind turbine when operating in the spinning reserve mode;
defining a reliability band around the calculated available power based on data of real available power and calculated available power such that the real available power lies within an upper bound and a lower bound of the reliability band;
selecting a reliability factor, wherein the reliability factor defines a probability that a reliable available power within the reliability band is below the real available power;
determining the reliable available power based on the selected reliability factor and the reliability band;
determining a power setpoint for the wind turbine based on a difference between a desired spinning reserve and the determined reliable available power; and
controlling the wind turbine to operate in the spinning reserve mode in accordance with the power setpoint.
