Robust Economic Dispatch with Energy Storage as Reserve Provider Considering the Correlation Between Uncertainties

To help the renewable-integrated power system operate in a secure, economic, and low-carbon way and fully unleash the potential of energy storage, this paper presents a novel approach for determining the optimal generation and reserve scheduling. First, uncertainties associated with the wind power output and load are modeled with the consideration of the correlation between uncertainties, the affine policy is introduced, and detailed energy storage operation constraints with it as reserve provider are formulated. Next, a robust economic dispatch model is developed, incorporating low-carbon factors. Then, the solution strategy is outlined to transform the model into a deterministic form. Finally, case studies are conducted to demonstrate the rationality and effectiveness of the proposed approach.
