Economic Dispatch Analysis of Comprehensive Energy System Considering Carbon Trading

In the context of energy internet and low-carbon power, integrated energy systems have become an important carrier for energy saving and emission reduction. Aiming at the schedulable value of integrated energy service providers including electricity, heat and natural gas loads in the electricity market and the natural gas market, a low-carbon dispatch model for power systems considering the response of integrated energy service providers was established. The carbon trading mechanism is introduced into the system's scheduling model, and a ladder calculation model for calculating the carbon trading cost in the carbon emission interval is constructed; considering the carbon trading cost and the cost of outsourced energy, a system suitable for electricity, heat and gas supply is established Low-carbon economic dispatch model. By comparing and analyzing the scheduling results of the three scheduling models, the effectiveness of the proposed model in considering the low-carbon and economic aspects of the system is verified. The analysis of the example shows that considering the response of integrated energy service providers in the electricity and natural gas market can reduce the carbon emissions of the power system and the operating cost of the entire system. The carbon trading mechanism and the comprehensive demand response are managed from the power generation side and the load. Effective means.
