摘要(Abstract)：

为解决电源侧电池储能参与辅助服务的间接效益无法量化,以致收益分配依据不足的问题,提出一种计及机组降损与延缓投资收益的储能经济效益建模及评价方法。首先基于全寿命周期理论完善储能参与调频调峰的成本模型,然后以转子疲劳寿命损耗理论为基础量化了火电厂配置储能参与调频的间接收益,同时建立计及储能调频降低机组磨损收益与储能调峰延缓投资的效益模型。最后基于成本和效益模型,采用动态投资回收期、投资收益率以及净现值等指标对配置储能系统的火电厂进行经济效益评价。算例仿真表明,通过计及储能对机组降损与延缓投资等间接收益,可有效提高储能系统的效益;采用优化运行策略,电源侧储能的各评价指标接近行业内各指标基准,可为未来电源侧投资储能及参与辅助服务市场机制的制定提供参考。
