Benefit Equilibrium Optimization of Pumped Hydro Storage Participating in Hydro-Thermal Bundling for Cross-Regional Consumption and Absorption

At present, the problem of benefit distribution of multi-energy joint delivery alliance which is affected by the "dual carbon" target needs to be solved urgently. On the basis of the traditional Shapley value method, considering the contribution fairness, four indexes of resource input, risk allocation, carbon policy influence, and contribution degree are introduced, and the improved Shapley model based on the cloud gravity method is constructed. The example analysis shows that compared with the traditional Shapley value allocation strategy, the improved Shapley model based on the cloud gravity method better matches the benefits of the subject and the comprehensive contribution.
