1. A method for operating a wind turbine, the method comprising:
increasing electric power output of the wind turbine from an initial power value at a first power ramp rate;
when reaching an intermediate power value, increasing the electric power output to a target power value at a second power ramp rate that is different from the first power ramp rate;
wherein the intermediate power value is the sum of the initial power value and a predetermined power difference; and
wherein the predetermined power difference is a predefined percentage of the target power value that is determined prior to the step of increasing electric power output of the wind turbine at the first power ramp up rate.
