摘要(Abstract)：

储能作为重要的高弹性资源,能够为电网运行提供调峰、调频等辅助服务。针对电力市场环境下储能参与调频市场机制与考虑储能寿命的收益模型开展研究。基于基本市场框架建立了储能参与调频市场收益模型,分析储能充放电速率、充放电深度和储能荷电状态对储能电池寿命衰减的影响,通过类雨流计数法考虑了储能循环寿命对调频收益的影响。根据浙江电力市场典型方式仿真数据,对不同储能电站规模、储能放电容量及电池100%充放电深度循环寿命次数下的储能参与调频市场全寿命周期收益进行仿真分析,为相关研究提供参考。
As an important highly flexible resource, battery storage can provide auxiliary services such as peak regulation and frequency regulation for power system operation. This paper launches research of market mechanism for energy storage participating in frequency regulation and return model considering energy storage lifespan in the context of electricity market. First, a return model is built based on the basic power market framework; then the influence of charge and discharge rate of energy storage, depths of charge and discharge and energy storage SoC on battery life attenuation is analyzed, and the influence of energy storage cycle life on returns of frequency regulation is analyzed through the rain flow counting method. Finally, the returns for grid-scale battery storage in regulation market during the battery life is estimated in different energy storage station scales, energy storage discharge capacities and 100 percent depth of discharge battery life based on the simulation operation data of the Zhejiang power market.
