电化学储能系统参与调峰调频政策综述与补偿机制探究

近年来，储能参与电网调峰调频辅助服务的政策层出不穷，有必要对其进行梳理与分析。本文结合电化学储能调峰调频性能与电化学储能电站运行案例，从国家、区域、省市三个层面剖析了近年来储能参与调峰调频辅助服务的政策，并归纳了典型省份对储能参与调峰调频辅助服务的准入要求、交易价格与交易模式。随后，分别从美欧储能参与调频补偿方式，以及我国主要的调频补偿方法两个方面探究了储能参与调频的补偿机制；以青海省为例，梳理了我国储能参与调峰的主要方式与补偿机制。最后，简要分析了现阶段储能参与调峰调频辅助服务的问题，从完善差异化补偿、优化储能调频调控方案、探索共享储能运营模式、完善准入及评价标准等方面对电化学储能参与调峰调频辅助服务提出了建议。

Review on the policies and compensation mechanism of BESS participation in the auxiliary service of frequency and peak modulation

With numerous policies of energy storage participating in the peak and frequency modulation service been re-leased, it is necessary to make clear analysis about those policies. In this paper, policies and cases of battery energy storage system (BESS) participating in the auxiliary service of peak and frequency modulation are summarized from the national, regional and provincial sides, combined with the frequency and peak modulation characteristics of BESS. The admittance requirement, compensation price and trading mode in typical provinces are summarized. Then, the compensation mechanism for BESS participating in frequency modulation service in the United States and Europe, as well as two compensation mechanisms in China are discussed, and the modes and mechanism of BESS participating in peak modulation in China are summarized, taking Qinghai province as an example. Finally, the existing problems of BESS participating in peak and frequency modulation under the existing policies are briefly analyzed. Suggestions related to those problems are put forward from the aspects of differential compensation, optimal allocation of frequency modulation resources, the mechanism of energy storage sharing and evaluation standard.
