摘　　要：为探究光伏储能系统节能、减排及降本潜力,开展铁路车站太阳能光伏储能系统设计,构建全生命周期环境经济核算方法模型。以铁路车站为例,设计屋顶式光伏储能系统,核算全生命周期碳排放当量为2.62×10^(3)t CO_(2)e,仅为国家电网发电和可再生能源占比较高的地方电网发电碳排放当量的10%和37%;光伏储能系统全生命周期大气污染物不产生PM2.5排放,SO_(2)和NOx大气污染物排放量分别为4.58 t和3.66 t,远低于国家电网;光伏储能系统全生命周期经济成本也最低,仅为地方电网和国家电网供电电费的20%和25%。相比于国家电网和区域电网供电方式,光伏储能供电的碳排放回收期分别为2.5年和9.3年,显著低于光伏组件使用年限25年,具有优越的环境与经济效益,为铁路车站运营供电方式选择提供借鉴。To explore the potential of energy saving,emission reduction,and cost reduction of the photovoltaic energy storage system,this study carried out the design of a photovoltaic energy storage system for railway stations,and built its life cycle environmental economic accounting model.Taking actual railway stations as an example,a rooftop photovoltaic energy storage system is designed and the CO_(2)emission equivalent of the life cycle is calculated to be 2.62×10^(3)tCO_(2)e,which is merely 10%and 37%of the CO_(2)emission equivalent of the national grid power generation and the local power grid power generation with a high proportion of renewable energy.Additionally,the atmospheric pollutants in the life cycle of the photovoltaic energy storage system do not produce PM2.5 emissions,and the emissions of SO_(2)and NOx are 4.58 t and 3.66 t,respectively,far lower than those of the national grid.Moreover,the life cycle economic cost of the photovoltaic energy storage system is also the lowest,which is only 20%and 25%of the electricity cost of local grid and national grid power supply,respectively.Compared with the power supply methods of the national grid and regional grid,the carbon emission recovery period of photovoltaic energy storage and power supply is 2.5 years and 9.3 years respectively,which is significantly lower than the 25 year service life of the photovoltaic modules.Thus,it yields superior environmental and economic benefits,providing a reference for the selection of power supply modes for railway station operations.
