摘　　要：电热氢系统作为一种高效的综合能源供用系统受到广泛关注。然而,氢气的燃爆特性导致了其面临着安全性挑战。为此,提出了考虑安全性风险的电热氢系统优化配置方法。首先,分析电热氢系统的安全性,对电解槽和燃料电池的工作范围和工作温度进行约束;然后,基于氢气的非理想气体压强公式对储氢罐压强进行更为准确地约束,并基于TNT当量法量化了储氢罐的安全性风险;最后,通过安全风险系数,将储氢罐的安全风险折算进目标函数中,建立了以系统投资成本、运行成本和安全性风险为优化目标的电热氢系统优化配置模型,并利用禁忌混沌量子粒子群算法进行求解。算例结果表明,在考虑安全性风险的情况下,通过合理的容量设计,可以在提高系统经济性的同时有效降低系统安全风险,进而验证了该优化设计方法的有效性。The electric-thermo-hydrogen system(ETHS),a highly efficient and integrated energy supply system,has attracted widespread attentions.However,the explosive characteristics of hydrogen poses unique safety challenges.To ensure the safe and economical operation of ETHS,this paper proposes an optimal configuration method considering safety risks.Firstly,the safety of the ETHS is analyzed,and the working range and temperature of the electrolysis cells and fuel cell are constrained.Then,the pressure of the hydrogen storage tank is more accurately constrained using the non-ideal gas pressure formula of hydrogen,and the safety risk of the hydrogen storage tank is quantified using the TNT equivalent method.Furthermore,the safety risk coefficient is used to convert the safety risk of the hydrogen storage tank into the objective function.The optimal configuration model of the ETHS is then established with the system investment cost,operation cost,and safety risk as optimization objectives,and the tabu chaotic quantum particle swarm optimization(TCQPSO)algorithm is employed to solve the model.The case study results demonstrate that with consideration of safety risks,the economy of the system can be improved through reasonable capacity design while effectively reducing system safety risks,which verifies the effectiveness of the optimization design method proposed in this paper.
