基于能值的水泥产消者电-碳融合可持续性分析OA北大核心CSTPCD

The environmental and ecological sustainability of factories from energy consumers to prosumers is still a mystery.Taking a power prosumer of a cement plant as an example,based on the emergy analysis method,an effective emergy sustainability index(EESI)of photovoltaic power generation system was proposed,subsequently,statistical and comprehensive calculations were conducted on the costs and"free"resources invested in the distributed photovoltaic power generation system throughout its lifecycle.Furthermore,the calculation method of green card and carbon offset electricity based on the emergy index was proposed.Then,the carbon reduction effects in different electricity consumption patterns and natural value of electricity-carbon-green power certification integration generated of this prosumer were quantified and compared.The results show that the distributed photovoltaic system of this prosumer has low emergy demand per unit power output,the"self use,surplus power access"mode of this prosumer is compatible with the economy to achieve efficient carbon reduction,and the emergy index reduces the monthly green card and carbon market tradable volume of this prosumer.Therefore,it is necessary to improve the emergy sustainability of power prosumers of cement plants,and to advocate personalized electricity carbon securities trading in mechanism development,so as to achieve the harmonious development of energy supply and ecological services.
