具有激励相容和能源共享特性的混合储能组合拍卖

Aiming at the problem ol the low energy storage economy of the separate configuration of integrated energy microgrids, a cost-effective electro-heat hybrid energy sharing model was established in the paper in which multiple integrated energy microgrids shared a single electro-heat hybrid energy storage device. In the research of electricity-heat hybrid energy storage capacity sharing, a hybrid energy storage combination auction method based on multi-item auction theory was adopted: Each microgrid submits multiple sets of different electricity and heat storage capacity requirements and corresponding bidding prices, bids for electrochemical energy storage capacity and heat storage tank capacity respectively, and uses the energy storage capacity to save the costs of purchasing electricity. Energy storage operators determined the outcome of the auction with the goal of maximizing social welfare, that is, how to allocate the energy storage capacity to each microgrid to maximize its utility. In the final fee settlement process, the Vickrey-Clarke-Groves (VCG) mechanism was used to calculate the fees to be paid by each microgrid. Due to the incentive compatibility of the VCG mechanism, each microgrid had no incentive to make false quotations and tended to submit the real bid price, which ensured that the combined auction results had the greatest social welfare. The example results show that in terms of social welfare, the hybrid energy storage portfolio auction proposed in this paper has more advantages than the general shared energy storage model.
