近年来,为提升能源系统韧性,电氢耦合综合能源系统的相关研究逐渐受到关注。提出了一种高时间分辨率(小时级)的能源系统韧性量化评价方法,并构建了一个自下而上的多目标优化模型,规划电氢耦合综合能源系统方案,旨在应对能源系统三难困境(经济−环境−韧性),评估电氢耦合技术在综合能源系统中的应用效益。以中国东南沿海某工业园区为案例,将文中提出的方法与模型应用于该园区的能源系统,根据极端事件对能源系统的干扰规律,在4种碳排放限制情景下进行多目标优化,以确定各情景下的最优方案。案例研究结果表明,由于目前电氢耦合技术应用成本较高,只有在对能源系统环境性和韧性均有要求下,电氢耦合技术应用才具有较大的价值。随着碳排放约束加强,经济性目标函数的净现值成本从全局情景的4.48×1010元上升至强碳排放限制情景的4.74×1010元,增长了5.80%。韧性指标则从5061.62MWh下降至4184.01MWh,减少了21%,电氢耦合显著提升了系统的环境性与韧性。最优化方案表明,氢储能不仅是跨季节长期储能的有效解决方案,其在短期储能中的独特优势同样值得关注。最后,将提出的韧性量化评价新方法与前人方法进行对比,可使优化方案净现值提高0.9%,系统最低供能水平提高5.19%,系统恢复能力提高12.57%。

In recent years,interest in electricity-hydrogen coupled integrated energy system is growing to enhance system resilience. Thispaper proposes a quantitative evaluation method of energy system resilience with high time resolution (hourly level),and constructs abottom-up multi-objective optimization model to plan the park-level electricity-hydrogen coupled integrated energy system,to cope withthe triple dilemma of the energy system (economic-environmental-resilience),and to assess the benefits of the application of electricity-hydrogen coupled technology to integrated energy system. In this paper,the methods and models proposed are applied to the energysystem of an industrial park along the southeast coast of China as a case study,and multi-objective optimization is carried out under fourcarbon emission limitation scenarios according to the disturbance pattern of extreme events on the energy system in order to determinethe optimal solution under each scenario. The results of the case studies indicate that,due to the current high cost of electricity-hydrogencoupled technology applications,electric-hydrogen coupled technology applications are of greater value only when both environmentaland resilience of the energy system are required. With the strengthening of carbon emission constraints,the net present value cost of theeconomics objective function increases from 4.48×10 CHY in the global scenario to 4.74×10 CHY in the strongest carbon emission limitation scenario,which is an increase of 5.80%. The resilience indicator,on the other hand,decreases by 21% from 5061.62 MWh to4184.01 MWh,and the electricity-hydrogen coupling significantly improves the environmental and resilience of the system. The optimalsolution shows that hydrogen storage is not only an effective solution for long-term energy storage across seasons, but its uniqueadvantages in short-term energy storage are also worthy of attention. Finally,comparing the new method of quantitative evaluation ofresilience proposed in this paper with the representative previous method,it can improve the net present value of the optimized solutionby 0.9%,the minimum level of system energy supply by 5.19%,and the system resilience by 12.57%.
