摘　　要：共享储能在电力供应链的各个环节中已经呈现出极强的应用潜力和价值,被视为解决储能成本疏导困难的有效手段。然而,储能共享不仅会涉及多类型应用场景,且其本身的运行方式是功率、容量等多维参数耦合的,亟须探索高效的储能共享机制,以最大化挖掘系统灵活性潜力。为此,围绕考虑多维参数耦合的共享储能匹配交易机制展开研究。首先,构建考虑多维参数耦合的共享储能匹配交易框架,在此基础上,基于组合拍卖理论构建多维参数耦合的共享储能匹配交易模型。其次,针对传统方法求解组合拍卖计算复杂度较高的问题,提出投标密度的概念,以单位标的物的价值对投标信息进行价值评估并排序,以此实现共享储能组合拍卖问题的快速求解,进而提出基于投标密度的共享储能匹配交易结算机制。最后,通过算例证明所提方法的有效性。Shared energy storage,which has shown great application potential and value in all aspects of the power supply chain,is regarded as an effective means to solve the problem of energy storage cost dredging.Nevertheless,energy storage sharing will not only involve multiple types of application scenarios;but its own operation mode is the coupling of multidimensional parameters such as power and capacity.It is urgent to explore an efficient energy storage sharing mechanism to maximize the flexibility potential of the system.For that reason,shared energy storage matching transaction mechanism considering multidimensional parameter coupling was studied.Firstly,a shared energy storage matching transaction framework considering multi-dimensional parameter coupling was proposed.On this basis,a shared energy storage matching transaction model with multidimensional parameter coupling was constructed based on the combinatorial auction theory.Secondly,in allusion to the problem of the high computational complexity of traditional methods for solving combinatorial auctions,the concept of bid density,which evaluates and sorts the bid information based on the value of the unit subject matter so as to realize the fast solution of the problem of shared energy storage combinatorial auctions,was proposed.In addition,a shared energy storage matching transaction settlement mechanism based on bid density was proposed.Finally,the effectiveness of the proposed method was demonstrated by numerical examples.
