Yaw control method and device for wind generating set, electronic equipment and storage medium

The embodiment of the invention provides a yaw control method and device for a wind generating set, electronic equipment and a storage medium, and belongs to the technical field of control. The method comprises the steps that yaw actions of a draught fan are discretized, an N-way tree about the yaw actions of multiple step lengths is generated, branch sequences meeting sequence invalidation conditions in the N-way tree are cut off, the pruned N-way tree is obtained, and the N-way tree is subjected to yaw control; and according to a set control step length, selecting a control action solution matched with the control step length from the trimmed N-way tree as a target action solution, calculating a control sequence corresponding to each target action solution, and selecting an optimal control sequence from a plurality of control sequences, thereby greatly reducing a searchable solution space of the optimal control sequence, and improving the accuracy of the optimal control sequence. Therefore, the calculation
