摘　　要：在当前“碳达峰,碳中和”战略目标下,针对孤立能源系统的能源自给及低碳化需求,本文提出一种孤立综合能源系统的净零碳日前优化调度方法。该方法首先基于物质的量守恒和能量平衡原理,分析异质能量的转换和碳元素流转过程,并以氢能和碳为中心,提出面向孤立综合能源系统的净零碳运行机制;然后以孤立能源系统的日成本最优为目标,考虑净零碳运行机制、电力系统运行约束和天然气系统运行约束,建立了孤立综合能源系统的日前优化调度模型,并将该模型转化为混合整数线性规划问题;最后以IEEE 39-NGS20电-气互联系统作为测试系统进行仿真分析,仿真结果表明,本文所提方法可以实现综合能源系统的100%自给和净零碳运行,并明显提升孤立综合能源系统日前调度的经济性。In view of the carbon peaking and carbon neutralization goals,this paper proposes a net⁃zero carbon emis⁃sion day⁃ahead optimal scheduling method for the isolated integrated energy system based on the hydrogen⁃carbon coupling,to address the self⁃sufficiency and low⁃carbon energy supply of the isolated integrated energy system(IIES).First,the amount of substance and energy balance principles is applied to analyze the cycle of different kinds of energy and carbon atoms.The net⁃zero carbon emission operating mechanism is proposed based on hydrogen and carbon.Then,a net⁃zero carbon emission day⁃ahead optimal scheduling model for IIES is established.The daily total cost of IIES is minimized in the optimization model,and the net⁃zero carbon emission mechanism,operation of power system and natural gas systems are considered by constraints.The model was transformed into a mixed integer linear programming problem.Finally,a simulation is implemented by using IEEE 39⁃NGS20 electric⁃gas interconnec⁃tion system.The simulation results show that the proposed method achieves 100%self⁃sufficiency and net⁃zero carbon emission operation of the system,and significantly improves the economy of the day⁃ahead scheduling of the IIES.
