The invention discloses an integrated scheduling method for demand-side resources and renewable energy in an intelligent distribution network environment. The method comprises the following steps that: the basic information of a power distribution network system is obtained, wherein the power distribution network system comprises a scheduling center, at least one response agent in communication connection with the scheduling center, and at least one demand-side resource in communication connection with the response agents; a rolling optimization scheduling model under multiple time scales is established according to the basic information, wherein the scheduling model comprises an objective function and constraint conditions, wherein the objective function is used for calculating the operation cost of the power distribution network system, and the optimization objective of the scheduling model is to minimize the value of the objective function; the optimal solution of the scheduling model is calculated, wherein the optimal solution comprises the optimal load of each demand-side resource; and the load of each demand-side resource is adjusted to be the optimal load. Therefore, the distributed demand-side resources are scheduled orderly, the operation cost of the power distribution network system is reduced, peak load shifting can be realized, and renewable energy consumption can be improved. The invention also discloses a corresponding computing device.
