A method for operating an asynchronous generator comprising receiving an
indication that a power grid frequency is reduced. Responsive to the
receiving the indication, reducing a speed of the asynchronous generator
from a first speed to a second speed for a first time period, wherein the
reduction of the speed of the asynchronous generator results in a
momentary increase in a total power output of the asynchronous generator.
Increasing the speed of the asynchronous generator from the second speed
to a third speed responsive to the end of the first time period.
