The invention belongs to the technical field of power system operation and control, and provides a multi-time-scale evaluation method and system for the schedulable capability of an active power distribution network. The method comprises the steps of model construction: constructing an energy storage equipment response model and an electric vehicle response model; in the first stage, parameter information of schedulable resources of the active power distribution network is determined according to the temperature control load response model, the energy storage equipment response model and the electric vehicle response model, the upper and lower bounds of the aggregation schedulable capability range of the active power distribution network are evaluated, and a first-stage evaluation range is obtained; in the second stage, according to the evaluation range of the first stage, simulating the scheduling instructions, and checking whether all the scheduling instructions in the pre-evaluation range can be responded
