【摘要】 针对北京某大型商场构建的光-气-储互补的综合能源系统展开研究，提出全生命周期优化方法，以全生命周期最小环境影响为目标函数，优化设备变工况运行下的容量配置。基于电跟随、热跟随两种运行策略，考虑多余的热、电产品是否计入环境收益构建4种场景；计算分析4种场景下的能耗和污染物排放，并研究全球变暖、酸雨和人体呼吸系统3种环境影响因素对全生命周期环境的影响程度。研究结果表明：电跟随运行策略在考虑剩余产品的环境收益方面优于热跟随策略，电跟随策略的效益案例对全生命周期环境的影响较小。更多还原

【Abstract】 In this paper, we study the integrated energy system of light, gas and storage in a large shopping mall in Beijing, and propose a whole life cycle optimization method, which takes the minimum environmental impact of the whole life cycle as the objective function to optimize the capacity allocation of equipment under variable working conditions. Based on the two operation strategies of electric follow-up and heat-following, four scenarios were constructed considering whether the excess heat and electrical products were included in the environmental benefit. The energy consumption and pollutant emission under the four scenarios were calculated and analyzed, and the impact of global warming, acid rain and human respiratory system on the whole life cycle environmental impact was studied. The results show that the electric follow-up strategy is better than heat-following strategy in considering the environmental benefits of the remaining products, and the benefit cases of the electric follow-up strategy have less impact on the whole life cycle environment.更多还原
