储能使用权是为了让更多的人共享储能，充分发挥储能的价值而提出的一个新概念。然而，目前还没有关于ESURs的招标、清算和定价一体化方法的报道。本文设计了一些新的ESURs，包括离散功率容量权(DPCR)和连续能量容量权(CECR)，以满足用户共享ES的不同需求。ESUR交易被描述为一个双层问题，其中上层问题表示用户的竞价策略，下层问题表示市场出清。提出了一种定价策略，通过保证两个层次上的问题的最优性来使交易有效和公平。利用Karush-Kuhn-Tucker(KKT)条件和二进制展开技术，将两层模型转化为一个线性问题，便于求解。此外，还可以从理论上证明每个参与者的收益都是非负的。数值实验验证了该方法的有效性。与DPC交易相比，由于额外考虑了CECR的交易，参与者的整体利润增加了23.6%-145.91个百分点。
Energy storage use right (ESUR) is a novel concept to make more people share the energy storage (ES) and give full play to its values. However, the integrated bidding, clearing and pricing method of ESURs is never reported nowadays. In this paper, we design some new ESURs, including the discrete power capacity right (DPCR) and the continuous energy capacity right (CECR), to meet the different needs of subscribers for sharing the ES. The ESUR trade is formulated as a bilevel problem, in which the upper-level problem represents the bidding strategies of subscribers, and the lower-level problem represents the market clearing. A pricing strategy is proposed to make the trading effective and fair by ensuring the optimalities of problems in both two levels. Using the Karush–Kuhn–Tucker (KKT) conditions and the binary expansion technique, the bilevel model is transferred into a linear problem to facilitate solving the model. In addition, it can be theoretically proved that the profit of each participant is non-negative. Numerical experiments are provided to demonstrate the effectiveness of the proposed method. Compared with the trading of DPCR, the participants’ overall profit is increased by 23.6%–145.91% owing to the additional consideration of the trading of CECR.
