Low Carbon Economy Optimization of Integrated Energy System Considering Electric Vehicle Charging Mode and Multi-Energy Coupling
In order to enable a multi-energy coupling integrated energy system(IES)to meet the needs of load diversity in low-carbon economic operation,a bi-level optimal configuration method for low-carbon economic operation of multi-energy coupling IES in different charging modes of electric vehicles(EVs)is proposed.First,an IES including cold-thermal-electric-gas coupling is established.Then,in the day-to-day operation stage,factors such as hierarchical carbon trading mechanism and different charging modes of EVs are considered to achieve the lowest daily scheduling cost.In the configuration planning stage,based on the daily operation cost,the equipment capacity is configured with the lowest equipment investment cost and annual operation cost.Finally,Cplex is used to solve the above two-stage objective functions and obtain the optimal configuration scheme and scheduling results through mutual iteration.The results show that the charging method considering the remaining charge of EVs and carbon trading mechanism can significantly reduce carbon emissions and operating costs of the system.The proposed configuration approach can well realize low-carbon economic operation of the multi-energy coupling IES.
