Robust Unit Commitment with Energy Storage Participating in Reserve

To ensure the secure, economic, and low-carbon operation of the renewable-integrated power system and fully unleash the potential of energy storage, this study presents an approach for determining the optimal unit commitment, generation, and reserve scheduling using robust optimization. First, uncertainties associated with wind power output and load are modeled, the affine policy is introduced and detailed energy storage operation constraints are formulated with it participating in reserve. Then, a robust unit commitment model is developed, incorporating low-carbon factors. Next, the solution strategy is explained to transform the model into a deterministic form. Finally, case studies are conducted to assess the rationality and effectiveness of the proposed approach.
