The embodiment of the invention provides a control method and device for a wind turbine generator set after icing, the wind turbine generator set and a storage medium, and the method comprises the steps: obtaining the operation state parameters and environmental meteorological parameters of the wind turbine generator set, and on the basis of the condition that the icing grade is greater than a first preset icing grade, determining the icing grade of the wind turbine generator set; switching the wind turbine generator set from a normal operation state to a shutdown state; and when the first output power meets the first preset condition, the wind turbine generator set is converted from the upwind direction to the downwind direction, the wind turbine generator set is switched from the shutdown state to the preset operation state, and when the first output power meets the first preset condition, the wind turbine generator set is switched from the preset operation state to the shutdown state so as to achieve the v
