考虑阶梯式碳交易的电-气-热综合能源系统低碳经济调度

针对如何实现系统低碳经济调度的问题,将阶梯式碳交易引入电-气-热综合能源系统低碳经济调度模型中,综合考虑系统的低碳性和经济性.首先,分析传统碳交易机制和阶梯式碳交易机制的区别,并说明阶梯式碳交易机制的合理性.然后,建立含电转气和燃气机组的电-气-热综合能源系统模型,并在模型中引入碳交易机制,比较不同碳交易机制下系统的低碳性和经济性.最后,基于改进的IEEE 30节点电网模型、6节点热网模型、7节点气网模型的系统,利用CPLEX软件对此系统进行仿真,验证所提的阶梯式碳交易机制对降低系统碳排放的有效性,从而为综合能源系统低碳调度运行提供参考.

Low-carbon economic dispatch of electricity-gas-heat integrated energy system based on ladder-type carbon trading

To realize the low-carbon economic operation of the whole system, a ladder-type carbon trading is introduced in the operation model of electricity-gas-heat integrated energy system, and the low-carbon and economic conditions of the system are considered comprehensively. Firstly, the difference between traditional carbon trading mechanism and ladder-type carbon trading mechanism is analyzed, and the rationality of developing the ladder-type carbon trading mechanism is explained. Secondly, an electricity-gas-heat integrated energy system dispatching model for power-to-gas and gas-fired units is established, and a carbon trading mechanism is introduced in the model to compare the low-carbon and economy of the system under different carbon trading mechanisms. Finally, the simulation of system is carried on CPLEX software based on the coupled modified IEEE 30-bus system model, 6-node heat network model and 7-node gas network model. The effectiveness of reducing carbon emissions through the ladder-type carbon trading mechanism is verified, thus providing reference for low-carbon operation of integrated energy system.
