Yaw optimization control method, device equipment and medium by considering wake flow of wind power plant

The invention provides a yaw optimization control method, device equipment and medium by considering wake flow of a wind power plant. The method comprises the steps of establishing a wind power plantwake flow model and a wind turbine generator yaw optimization model; obtaining yaw optimization results in different wind condition intervals through the wind power plant wake flow model and the windturbine generator yaw optimization model; evaluating the loads of corresponding wind turbine generators based on the yaw optimization results in different wind condition intervals, and adding the yawoptimization results in the corresponding wind condition intervals to a preset yaw optimization strategy library when the loads pass evaluation; and acquiring the real-time wind condition of the windpower plant, calling a target yaw optimization result corresponding to the real-time wind condition from the yaw optimization strategy library, and then adjusting a yaw angle of the corresponding windturbine generators in the wi
