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.
