考虑碳捕集和碳交易机制的电-热综合能源系统低碳经济调度
Low-carbon Economic Dispatch of Integrated Electricity and Heat Energy System Considering Carbon Capture and Carbon Trading Mechanism
摘要
Abstract
In order to reduce the carbon emissions of the integrated energy system,a low-carbon economic opti-mal scheduling model for the integrated energy system of electric-thermal system considering carbon capture and carbon trading mechanism is proposed.Firstly,carbon capture unit,power-to-gas unit and supercritical CO2 Brayton cycle generator set are introduced into the system,and these units are modeled based on the pro-cess of CO2 production,capture and utilization in the system.CO2 captured by carbon capture equipment can provide raw materials for power to gas(P2G)equipment and working fluids for supercritical CO2 cycle units.Secondly,on this basis the economic dispatching model of the electric-thermal integrated energy system is con-structed,which takes the sum of the system operation cost as the optimization target.Finally,IEEE 39-node power system and 33-node thermal system are used for simulation analysis,and Gurobi 11.0 solver is called in MATLAB software to solve the problem.The results show that the carbon emission of the system is reduced by 42.9%,the wind and light abandonment rate is reduced by 6.0%,and the total cost is reduced by 4.3%due to the introduction of carbon capture and other units.The proposed model is conducive to the low-carbon economic operation of the integrated energy system.关键词
