The invention provides a control method capable of promoting a supercritical unit to participate in wind power dissipation, and belongs to the field of wind turbine set tuning control. The method aimsto solve the problem that an existing supercritical unit control technology cannot guarantee stable operation parameters in a unit, and the problem of heat storage needed for tracking the large-scalepower change of the unit can be rapidly and accurately supplemented. According to the method, the wind power signals are collected periodically, and the collected wind power signals are used for constructing a periodic boiler input acceleration signal BIR, and the constructed boiler input acceleration signal BIR is added into a boiler load instruction BM; and the absolute value of the steam pressure deviation signal delta pT is compared with a threshold value A; when |Delta pT|<=A, and Delta pT*Delta f(0, the energy of a power grid source is homeopathic, and the turbine load command TM is corrected, and the corrected
