The invention discloses a method for optimizing the capacity of a wind-light-water storage resource complementary power generation system in a region, and the method comprises the following steps: 1, setting a wind-light-water power supply objective function and constraint conditions, and enabling the wind-light-water power supply objective function to enable the abandoning rate of a wind-light-water power supply to be minimum and the utilization rate to be maximum; 2, on the basis of the step 1, an energy storage power supply objective function and constraint conditions are set, and the energy storage power supply objective function enables the cost of an energy storage power supply to be the lowest; and step 3, setting an evaluation index, and evaluating a power grid composed of the wind-light-water power supply and the energy storage power supply. According to the method, target functions and constraint conditions of the wind-light-water power supply and the energy storage power supply are set respectively
