Abstract: Under the dual background of network power strategy and "double carbon" goal, in order to solve the power supply pressure and energy saving and emission reduction problems caused by the increase of density and data volume of 5G mobile network, a low-carbon optimization operation strategy based on the collaboration of 5G base stations (BSs) and integrated energy system (IES) is proposed. Firstly, in order to optimize the energy management of the BSs and strengthen the interaction between the BSs and IES, the BSs sleep mechanism and the demand response model of the BSs energy storage battery are introduced, and their operation effects in different time and space are compared. Secondly, in order to promote the efficient coupling utilization between the BSs and IES electric-thermal energy, a 5G BSs waste heat model is established, which is coupled with the photothermal power station in IES to give full play to the energy supply potential of the two. Finally, in order to measure the low-carbon benefits brought by the addition of the BSs, the reward and punishment ladder carbon trading mechanism is introduced into the system decision-making, and the three-stage optimization scheduling model of the cooperative operation of 5G BSs and IES is constructed. The optimization model is simulated and analyzed under different operation scenarios. The results show that the operating costs of IES and 5G BSs decreased by 20.3% and 22.5% respectively after collaborative scheduling, and the carbon emissions of IES decreased by 24.2%.
