摘　　要：为构建低碳可持续能源系统,推动我国未来能源系统转型,文章聚焦能源系统中低碳与清洁,建立了考虑经济与碳排放的电-气-热-氢综合能源系统日前调度模型。首先,在综合能源系统网络中,考虑负荷不确定性建立了电网潮流模型以及热网、气网的动态潮流模型。在能量转换设备中考虑到氢能的清洁、高效、安全等优点,引入电转氢(power to hydrogen,P2H)设备和氢储能设备。考虑到燃气轮机、燃料电池等余热浪费,引入有机朗肯循环(organic Rankine cycle,ORC)余热发电将剩余热能转化为电能,提高能源利用效率。其次,考虑以系统运行成本和环境成本为目标函数,给出电-气-热-氢的综合能源系统最优运行调度方案。最后针对多种优化运行模式进行仿真分析,结果表明,文章提出的电-气-热-氢综合能源系统优化运行策略能够有效保证运行的经济性和环保性。In order to build a low-carbon sustainable energy system and promote the transformation of energy system,this paper focuses on low-carbon and clean energy systems,and establishes a day-ahead dispatch model of an electricity-gas-heat-hydrogen integrated energy system that considers economy and carbon emissions.Firstly,in the integrated energy system network,the power flow model of the power grid and the dynamic power flow models of the heating network and the gas network are established considering the load uncertainty.Considering the advantages of clean,high-efficiency and safety of hydrogen energy in energy conversion equipment,power to hydrogen(P2 H)equipment and hydrogen energy storage equipment are introduced.Taking into account the waste heat of gas turbines,fuel cells,etc.,the organic Rankine cycle(ORC)waste heat power generation is introduced to convert the remaining heat energy into electric energy and improve energy utilization efficiency.Secondly,the system operating cost and environmental cost are considered as the objective functions.Then the optimal operation dispatching plan is put forward for the electricity-gas-heat-hydrogen integrated energy system.Finally,this paper conducts simulation analysis for multiple optimized operation modes.The simulation results show that the optimized operation strategy of the electricity-gas-heat-hydrogen integrated energy system proposed in this paper can effectively ensure the economic and environmental protection of operation.
