1. An intermittent characteristic-based demand-side resource coordination control method, comprising:
receiving a control request, wherein the control request is used for requesting control of demand-side resources having an intermittent characteristic;
determining an optimal total control quantity of demand-side resources;
determining a coordination strategy of a plurality of demand-side resources and an action quantity of each of the plurality of demand-side resources; and
performing coordinated control on the plurality of demand-side resources based on the optimal total control quantity of demand-side resources, the coordination strategy, and the action quantity of each of the plurality of demand-side resources;
wherein determining the optimal total control quantity of demand-side resources comprises:
determining an objective function min
