    摘要: A method and system for controlling the output power from a renewable energy installation (10) to a utility grid (56) having a predetermined bound for a variation in output power per unit of time is provided. The method and system includes constraining an output signal of a controller (76) to an upper and/or lower limit via a limiter (78), wherein the upper and/or lower limit comprises a predetermined upper and/or lower bound for a variation in output power per unit of time. The constrained output signal is then applied to the plurality of electricity generators (12, 14, 16) to limit the variation in output power per unit of time according to the predetermined bound.
