参与辅助服务的用户侧储能优化配置及经济分析

为使用户侧储能收益最大化，提出了一种参与辅助服务市场的用户侧储能优化配置方法。首先，建立了用户侧储能的全生命周期成本和考虑辅助服务的收益模型；其次，在两部制电价下，基于对储能电池运行特性和用户负荷特性的考虑，建立了一种参与辅助服务的用户侧储能优化配置模型，以储能容量和辅助服务参数为优化变量，对工业用户全寿命周期的净收益进行优化计算；然后，以广西储能辅助服务市场为例，实现了用户侧储能最优容量下的配置优化，确定了参与辅助服务的变量值；最后，通过改变政策敏感度对比分析了不同辅助服务的经济效益，给后续储能投资提供了指导性意见。

Optimal Configuration and Economic Analysis of User-Side Energy Storage Participating in Auxiliary Services

In order to maximize the benefits of user-side energy storage, a user-side energy storage optimization allocation method is proposed to participate in the auxiliary service market. First, a life-cycle cost model of user-side energy storage and a benefit model considering ancillary services are established. Secondly, under the two-part electricity price system, based on the consideration of the operating characteristics of energy storage batteries and user load characteristics, a user-side energy storage optimization configuration model is established to participate in auxiliary services. The energy storage capacity and auxiliary service parameters are taken as optimization variables to optimize the net income of industrial users during the whole life cycle. Then, taking the energy storage auxiliary service market in Guangxi as an example, the optimization of configuration under the optimal user-side energy storage capacity is realized, and the variable values involved in the auxiliary service are determined. Finally, the economic benefits of different auxiliary services are compared and analyzed by changing the policy sensitivity, which provides guidance for future energy storage investment.
