摘　　要：首先,分析电解槽以及燃料电池等设备工作特点,计及设备的动态能效,建立氢系统设备的精细化模型;其次,建立各种能源间的耦合关系模型,通过电热氢多种储能实现电热气氢系统的能量平衡;最后,计及电热气负荷的波动与可再生能源的不确定性,以日运行成本最小为目标,建立电热气氢综合能源系统随机优化调度模型。算例分析验证了该优化模型能有效消纳风光资源、降低日运行成本、减少环境污染,具有较好的经济性与环保性。Firstly,the working characteristics of electrolyzers and fuel cells have been analyzed.A refined model of the hydrogen system equipment is built considering the dynamic efficiency.Secondly,the coupling relationship model between energy sources is constructed,the energy balance of the integrated energy system is realized by introducing multiple energy storages.Finally,a stochastic optimal scheduling model of the integrated electric-heat-gas-hydrogen energy system is established considering the fluctuation of load and the uncertainty of renewable energy.Case studies verify that the proposed optimization model can effectively consume wind and photovoltaic energy,reduce operation cost and mitigate environmental pollution.
