Zusammenfassung:	The invention discloses a wind power plant multi-unit frequency modulation reference power collaborative distribution method. The method comprises the following steps: obtaining a mathematical relationship between a rotor kinetic energy factor representing frequency modulation capability and rotor kinetic energy; obtaining a mathematical relationship between a unit capacity factor representing the frequency modulation capability and the operating point power; determining a setting algorithm of a cooperative control coefficient Kai based on the rotor kinetic energy factor and the unit capacity factor; and a cooperative control coefficient Kai is introduced into the frequency modulation strategy module, so that the frequency modulation reference power of the wind turbine generator operating under different wind conditions is distributed according to energy. According to the multi-unit frequency modulation reference power collaborative distribution method for the wind power plant, on the basis of a comprehensive
