The invention discloses a wind-storage combined system scheduling method and apparatus capable of improving the wind power schedulability. The scheduling method includes: the available scheduling output of a wind-storage combined system is calculated via the current charge state of a storage battery and the wind power prediction output; a scheduling model containing the wind-storage combined system is established, and the scheduling model is formed by a target function and restriction conditions; the target function serves as the bacteria fitness value, an improved bacteria foraging algorithm is employed to solve the scheduling model; and if the solution result satisfies all the restriction conditions, the solution result is the optimal solution and is outputted. The scheduling apparatus comprises a calculation module, an establishing module, a solution module, and an output module. According to the method and the apparatus, based on an operation strategy of the wind-storage combined system, the scheduling model of the wind-storage combined system is established, the improved bacteria foraging algorithm is improved for solution, the economy of the operation of the wind-storage combined system is fully considered, the wind power schedulability is effectively improved, the wind power utilization rate is increased, and the method and the apparatus are applicable to the coordination scheduling of the wind-storage combined system.
