The invention relates to an energy storage capacity configuration method for improving the stability of a power system based on high-proportion new energy consumption, and the method comprises the steps: building a system operation optimization sub-model with the lowest system operation cost and the maximum system stability as double targets; establishing a capacity optimization configuration parent model by taking the minimum total cost of the system as a target and taking the conditions that the new energy discarding rate does not exceed the maximum allowable new energy discarding rate and the rated energy storage capacity to be configured does not exceed the energy storage capacity limit value as constraint conditions; solving a system operation optimization sub-model by using a beetle foraging multi-objective optimization algorithm, transmitting the system operation cost and the new energy abandoning rate to a parent model, and transmitting the rated energy storage capacity to be configured to the sub-mod
