The invention belongs to the technical field of electric power system operation and control, and provides a transmission and distribution collaborative random scheduling method and system based on scene reduction. In the scene reduction process, the concept of target optimality distance for measuring the similarity between different random scenes is put forward; dividing each original scene into the category of the reduced scene according to the target optimality distance between the original scene and the reduced scene, and carrying out iterative clustering to obtain a plurality of reduced classic scenes; according to the scene reduction method based on the target optimality distance, the scene can be effectively reduced, the operation burden can be remarkably reduced, compared with a traditional scene reduction method based on the Wasserstein distance, the obtained reduced scene can better approximate to the original random scheduling problem, and the scheduling reliability of transmission and distribution
