Multi-stage planning of park-level integrated energy system based on ladder-type carbon trading mechanism

针对能源互联背景下的园区综合能源系统规划问题,为了充分考虑园区综合能源系统的低碳性以及建设时序,提出了一种基于阶梯碳交易机制的园区综合能源系统多阶段规划方法。构建了阶梯碳交易机制下的碳交易费用计算模型,以计及碳交易费用的全寿命周期成本最小为目标函数,建立了园区综合能源系统的多阶段规划模型,对各个规划阶段的设备配置进行最优决策。通过仿真探讨了多阶段规划的经济性以及阶梯碳交易机制的碳交易基准价格、碳交易价格区间长度、区间数目等参数与多阶段规划之间的相互耦合影响。仿真结果表明系统的碳排放对阶梯碳交易机制的参数变化较为敏感,且各参数中碳交易基准价格是影响规划结果的主要因素。

Aiming at the planning of park-level integrated energy system in the background of energy interconnection,a multi-stage planning method of park-level integrated energy system based on ladder-type carbon trading is proposed in order to fully consider the low-carbon characteristic and the construction time sequence of park-level integrated energy system.The calculation model of carbon trading cost under ladder-type carbon trading mechanism is established,based on which,the multi-stage planning model of the park-level integrated energy system is established with the minimum life-cycle cost including the carbon trading cost as the objective function,so as to make the optimal decision on the equipment configuration in each planning stage.Through simulation,the economics of multi-stage planning and the coupling effects of carbon trading benchmark price,carbon trading price interval length,number of intervals and other parameters on multi-stage planning are discussed.The results show that the carbon emission of the system is sensitive to the changes of ladder-type carbon trading’s parameters and the carbon trading benchmark price is the main factor affecting the planning result.
