| 摘要: |
| 针对传统一体化式共享储能存在的灵活性较差且无法兼顾多类型用户的差异性用电需求等问题，提出一种分散式共享储能系统优化配置与调度方法；针对用户通过储能补贴政策漏洞骗取补贴收益的问题，在已出台政府补贴政策的基础上，提出一种改进分时补贴策略。首先，以工业园区为应用背景，深入分析了分散式共享储能系统与多个工业用户的能量交互机理；然后，以多用户整体净收益最大化为目标构建了基于合作博弈的月前、日前两阶段优化调度模型，并采用Shapley值法对合作收益进行分配；接着，设计了以储能全寿命周期净收益、动态投资回收期、投资回报率为指标的储能投资评估方法；最后，通过对比一体化式共享储能和分散式共享储能的配置成本、运行经济性，对所提方法的有效性进行了验证。算例结果表明：所提分散式共享储能配置方法在降低工业用户初期投资成本、用电成本方面具有一定的先进性，所提改进分时补贴策略在防止用户投机骗补方面具有一定的有效性，对推动用户侧储能多元化发展具有理论指导意义。 |

| Abstract: |
| Aiming at the problems of traditional integrated shared energy storage system, such as poor flexibility and unable to take into account the different electricity demand of multiple types of users, an optimal configuration and scheduling method of decentralized shared energy storage system is proposed. Aiming at the problem that users cheat the benefits of energy storage subsidy through the loopholes of subsidy policy, an improved time-sharing subsidy strategy is proposed on the basis of the existing government subsidy policy. Firstly, the energy interaction mechanism between the distributed shared energy storage system and multiple industrial users is analyzed in depth with the application background of industrial park. Then, a cooperative game-based month-ahead and day-ahead two-stage optimization scheduling model is constructed to maximize the overall net profit of multiple users, and the cooperative profit is distributed by Shapley value method. Furthermore, the energy storage investment evaluation method is designed, which takes the life cycle net profit, the dynamic investment payback period and the rate of return on investment of energy storage as the indexes. Finally, the effectiveness of the proposed method is verified by comparing the configuration cost and operation economy of the integrated shared energy storage and the distributed shared energy storage. The numerical results show that the proposed configuration method of distributed shared energy storage is advanced in reducing the initial investment cost and electricity cost of industrial users, and the proposed improved time-sharing subsidy strategy is effective in preventing users from speculation and fraud. It has theoretical guiding significance for promoting the diversified development of user-side energy storage. |
