摘要

用户侧储能有助于负荷聚合商规避因需求响应偏差而导致的收益风险。共享储能作为一种创新应用模式,能够节约用户侧储能的投资容量并提升储能利用效率。设计了一种面向负荷聚合商的共享储能组合拍卖机制,以期通过提高共享储能设备利用效率,进一步降低负荷聚合商购买共享储能服务的成本。首先,设计一种将共享储能功率权与容量权以“与”投标形式进行组合拍卖的市场机制,以及该机制下各交易主体的参与方式及运营流程;其次,在满足投标约束条件下,构建以社会福利最大化为目标的竞胜标决定模型,设计在购售双方之间合理分配社会福利的定价机制,以及中标结算和违约惩罚相结合的资金结算机制,并分析各参与主体的效益;最后,通过算例验证该机制的有效性及优越性。

Abstract：

Customer-side energy storage system helps load aggregators hedge the revenue risk due to demand response deviations. As an innovative application model, shared energy storage system can save the investment capacity of user-side energy storage system and improve the efficiency of energy storage system utilization. A shared energy storage system portfolio auction mechanism for load aggregators is designed to further reduce the cost of shared energy storage system services purchased by improving the efficiency of shared energy storage system equipment utilization. Firstly, a market mechanism is designed to auction shared energy storage system capacity and power rights in the form of "with" bids, and the operation process of each trading entity under this mechanism. Secondly, under the constraints of bidding, a winning bid decision model is constructed with the objective of maximizing social welfare. A pricing mechanism is designed to share social welfare between buyers and sellers, as well as a capital settlement mechanism that combines winning bids and penalties for default, and the benefits of each participant are analyzed. Finally, the effectiveness and superiority of the mechanism is verified through arithmetic examples.

Key words： Load aggregators shared energy storage system "with" bids combinatorial auction mechanism design
