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.

There is described a method of controlling a wind power plant, the wind power plant comprising a plurality of wind turbines (102) and being connected to a power grid (120), the method comprising (a) detecting a grid frequency instability, (b) selecting a subset of wind turbines, (c) modifying a power reference for each wind turbine in the selected subset of wind turbines to respond to the grid frequency instability, and (d) applying the modified power references to the corresponding wind turbines in the selected subset of wind turbines. There further described a wind power plant controller, a wind power plant, a computer program, and a computer program product.
