Active power optimization scheduling method for smoothing output power of wind turbine generator

The invention belongs to the technical field of automatic control of wind power, and more specifically relates to an active power optimization scheduling method for smooth output power of a wind turbine generator. The method comprises the steps of obtaining active power generation power data of each fan and an overall active power reference value of a wind power plant; setting a wind power plant overall active power reference value issued by a power grid; an optimization function is set by minimizing the sum of the standard deviations of all the fans; setting constraint conditions of an optimization function according to the active power generation power data of each wind turbine generator set; after the optimization function with the constraint is set, solving by using an interior point method to obtain the optimal reference power at the t moment; and taking the optimal reference power solved at the moment t as the generation power output at the moment t, and participating in the calculation of the optimal r
