摘要:

在“双碳”目标引领下,电化学储能凭借其高效灵活的特性,成为新型电力系统中不可或缺的调节资源。当前亟需一种方法,能够全面量化储能在多元耦合辅助服务中的系统价值,并识别其价值形成的关键驱动因素,以支撑科学配置与政策制定。提出了一种面向多元耦合服务场景的电化学储能多维价值评估与归因分析框架。该方法构建了涵盖经济、技术与环境多维度的价值指标体系,系统反映储能在调峰、调频等多服务中的综合贡献。进一步地,基于随机森林模型识别系统运行特征对储能价值的非线性驱动关系,揭示复杂运行条件下的价值形成机制。算例结果显示,储能提供多元耦合服务可使系统惯量提升46.09%、最低频率改善0.21 Hz、碳排放强度降低18.9%,并在多维价值间呈现显著协同效应。所提方法可为储能的价值挖掘、功能定位与配置优化提供机制性、可解释的量化依据,服务于新型电力系统灵活性提升与低碳转型战略。

Abstract:

Driven by the "dual-carbon" goals, electrochemical energy storage (EES) has emerged as an indispensable flexibility resource in new-type power systems due to its high efficiency and operational flexibility. However, no systematic and interpretable framework is in place to comprehensively quantify the multidimensional values of EES across multiple coupled services and to identify the underlying drivers of value formation. Therefore, this paper proposes an integrated framework for multidimensional value and attribution analysis of EES under multi-service coupling scenarios. Firstly, a multidimensional value indicator system covering economic, technological, and environmental aspects is established to systematically reflect the comprehensive contribution of energy storage in multiple services such as peak shaving and frequency regulation. Furthermore, based on the random forest model, the nonlinear driving relationship between system operational characteristics and energy storage value is identified, revealing the value formation mechanism under complex operational conditions. The case study results demonstrate that energy storage providing multi-service coupling can increase system inertia by 46.09%, improve the minimum frequency by 0.21 Hz, reduce carbon emission intensity by 18.9%, and exhibit significant synergistic effects across multiple value dimensions. The proposed method offers a mechanism-driven and interpretable quantitative basis for value mining, functional positioning, and configuration optimization of energy storage, supporting the strategic goals of enhancing flexibility and promoting low-carbon transition in new-type power systems.
