Abstract

The complementarity between natural gas and solar energy is an effective way to improve energy efficiency and achieve energy conservation and emission reduction. This article constructs a light-gas-storage complementary combined cooling, heating and power （CCHP） system with complementary Based on the whole life cycle theory, taking the primary energy saving rate and total pollutant emission reduction rate as the objective functions, the optimization model of the combined cold, heating and power system is established, and the genetic algorithm is applied to optimize the capacity configuration under variable working conditions of the system. Incorporate the material recovery phase into the life cycle assessment and consider fuel transportation during the transportation phase. The results show that after optimization, the electric following （FEL） strategy of CCHP system can achieve better energy saving and emission reduction benefits. The separated production （SP） system has little environmental impact during the material recovery stage, and the CCHP system consumes much less fuel transportation than the SP system.
