Optimization of Capacity Allocation of Integrated Energy System Considering Life Cycle Carbon Emissions
The integrated energy system(IES)coupling multiple energy sources and equipment has a flexible energy supply and a high energy utilization rate,which is conducive to the low-carbon and clean transformation of the national energy structure.In this paper,optimizing it from the perspective of the life cycle was more conducive to the realization of the dual-carbon goal.Firstly,the carbon emissions in the life cycle of energy and equipment used in the integrated energy system were calculated,and then a bi-level optimization model including carbon transaction cost was established to optimize the capacity alloca-tion and dispatching operation of the integrated energy system.Three scenarios were set up to analyze the economy and carbon emissions of integrated energy systems and traditional energy supply systems.The re-sults show that the integrated energy system has better low carbon and economy than the traditional energy system.Energy consumption is the main body of carbon emissions in the life cycle of an integrated energy system,of which more than 20％comes from indirect emissions of various upstream power plants,and the carbon emissions brought by system equipment are only about 1％.Considering life cycle carbon e-missions in the optimization of integrated energy system can reduce carbon,but it does not occupy an eco-nomic advantage by combining the current electricity price,gas price and carbon trading price.
