Method and apparatus for controlling power of wind farm

An apparatus for controlling power of a wind farm, wherein the apparatus for controlling power comprises:

• at least one processor;
• at least one memory storing computer-executable instructions,
• wherein the computer-executable instructions, when executed by the at least one processor, cause the at least one processor to:
• acquire a historical equivalent fatigue load of a target component of each of a plurality of wind turbines in the wind farm during a target historical period;
• acquire, in response to entering a limited power cycle, an entire fatigue load, an equivalent fatigue load of the target component and a pay per unit power generation of each of the plurality of wind turbines at a current moment, wherein the pay per unit power generation of a wind turbine is obtained based on the equivalent fatigue load and power generation of the wind turbine;
• determine an optimal power value of at least one of the wind turbines according to the historical equivalent fatigue load as well as the entire fatigue load, the equivalent fatigue load and the pay per unit power generation, to ensure that a sum of power values of the plurality of wind turbines is less than or equal to a limited power value in the limited power cycle;
• and
• send a control instruction to the at least one of the wind turbines to adjust a power value of the at least one of the wind turbines to the optimal power value for the wind turbine.
