摘要：

新型配电台区配置多个共享储能(shared energy storage, SES)已成趋势，具有多资源协同的效果。但仅考虑SES自身价值难以实现其高效调用，需进一步关注共享储能个体差异对台区电网的多角度综合影响。为量化台区多共享储能共同作用下的单一SES边际运行贡献，提出了基于改进沙普利(Shapley)值的台区多共享储能运行效能分配方法。考虑新能源消纳及碳减排，建立含SES运行组合的台区运行成本最小优化调度模型；考虑SES对台区经济性、可靠性与环境的影响，建立SES运行效能评估指标，基于改进层次分析与层间相关性结合的主客观赋权法建立运行效能评估模型；考虑不同SES对台区运行的单方面效能差异，构建计及经济贡献度、可靠性贡献度与环境贡献度的SES修正因子以改进Shapley值法，将多种SES组合的运行效能分配至单个SES。对含3个SES的改进IEEE 33节点台区电网仿真验证，结果表明所提方法有效量化与分配不同节点SES对台区的综合效用，增加了对台区有益影响的SES1和SES2运行效能。所提方法为台区共享储能的高效率调度及潜力发挥提供全新思路。

Abstract:

The configuration of multiple shared energy storages (SESs) in a new distribution network (NDN) has become a trend, providing multi-resource cooperative effects. However, maximizing the efficiency of SESs requires more than just evaluating their value. The multifaceted and comprehensive impacts of each SES on the NDN must also be considered. To quantify the marginal operational contribution of a single SES under the joint effect of multiple SESs in the NDN, a method for allocating the operational efficiency of multi-SESs based on the improved Shapley value method is proposed. An optimized scheduling model was established to minimize operating costs in the NDN while considering new energy consumption and carbon emission reduction. The model includes operational efficiency evaluation indicators that evaluate the economic, reliability, and environmental impacts of SESs on the NDN. In addition, an operational efficiency evaluation model is established on the basis of a subjective-objective empowerment method, combining improved hierarchical analysis and inter-criteria correlation. To consider the differences in the unilateral efficiency of different SESs, correction factors were introduced to improve the Shapley value method. These factors consider each SES's economic, reliability, and environmental contributions to allocate operational efficiencies across multiple SES combinations. The proposed method was validated via simulations on an improved IEEE 33-node NDN with three SESs. The results demonstrate that the proposed method effectively quantifies and allocates the comprehensive utility of SESs at different nodes using the NDN. In particular, the operational efficiency of SES1 and SES2, which positively affect the NDN, is increased. The proposed method provides a new framework for the efficient scheduling and potential utilization of SESs in distribution networks.
