摘　　要：为推动集中式储能与多风电场站间的协调互动与合作共赢,促进新能源场站共享储能的可持续发展,对多风电场集中式共享储能的资源分配与价格机制进行研究。首先,构建多风电场站联合共享储能运行框架,以实现风电场站平滑稳定并网与集中式独立储能的共享使用。其次,基于维克里-克拉克-格罗夫斯(Vickrey-Clarke-Groves,VCG)机制提出具有激励相容特性的储能共享两阶段的交易机制。第一阶段建立以多风电场站为领导者、共享储能为跟随者的主从博弈运行模型,以确定风电场群与储能各时段的初始交易价格。第二阶段通过双向拍卖的方式,以社会福利最大化为目标对初始交易价格进行修正,并利用收支差额补偿法应对VCG机制收支不平衡问题,形成最终交易价格。最后,选取新疆地区的风电数据构建算例,验证所提机制的有效性。相比固定价格交易模式下风电场站与共享储能的交易结果,得出风电场站收益分别上升了11.14%、5.26%和6.61%,该机制为促进集中式共享储能的发展提供了参考。To promote cooperation between centralized energy storage and multiple wind farms for the sustainable development of shared energy storage,this paper explores the resource allocation and trading mechanisms for centralized shared energy storage in multi-wind farms.First,a joint operational framework for multiple wind farm shared energy storage is constructed to achieve smooth and stable grid connection of wind farms and shared use of centralized independent energy storage.Based on the Vickrey-Clarke-Groves(VCG)mechanism,a two-stage incentive-compatible trading mechanism for energy storage sharing is proposed.In the first stage,a master-slave game model with multiple wind farms as leaders and shared energy storage as followers determines the initial transaction prices between the wind farm cluster and the energy storage for each time period.The second stage uses a two-way auction mechanism to refine the initial transaction price,aiming to maximize social welfare.Additionally,the final transaction price is formed by using the compensation method for the difference between revenues and expenditures to address the imbalance between revenues and expenditures of the VCG mechanism.Finally,the effectiveness of the proposed mechanism is verified by an example using wind power data from the Xinjiang region.Compared with the trading results of wind farms and shared energy storage under the fixed-price trading model,the revenues of the wind farms are increased by 11.14%,5.26%and 6.61%,respectively.The mechanism provides a reference for promoting the development of centralized shared energy storage.
