Abstract

This paper proposes an economic and resilient operation architecture for a coupled hydrogen-electricity energy system operating at port. The architecture is a multi-objective optimization problem, which includes the energy system optimal economy as the goal orientation and the optimal resilience as the goal orientation. The optimal resilience orientation looks for the best resilience performance of the port through reasonable energy management including (1) reducing the amount of electricity purchased by the port power grid from the external power grid (2) improving the energy level of electric energy storage (3) improving the energy level of hydrogen energy storage. Taking the actual coupled hydrogen-electricity energy system of Ningbo-Zhoushan Port as an example, four typical scenarios were selected according to renewable generation and load characteristics, and a comparative analysis was carried out under the oriented operation. The results show that although the resilience orientation increases the operating cost compared with the economic orientation, the four scenarios reduce the load shedding by 44.84 %, 30.26 %, 48.49 % and 34.37 % respectively when the external power grid is disconnected. The impact of changes in resilience-oriented weight coefficients and hydrogen price on system resilience performance was investigated to provide more references for decision makers.

港口氢-电耦合能源系统的经济和弹性运行

本文提出了一种港口运行的氢-电耦合能源系统的经济、弹性运行架构。该体系结构是一个多目标优化问题，以能源系统最优经济性为目标取向，以最优弹性为目标取向。最优弹性取向是通过合理的能量管理，包括(1)减少港口电网从外部电网购买的电量(2)提高电力储能的能量水平(3)提高氢储能的能量水平，寻求港口的最佳弹性性能。以宁波-舟山港实际氢电耦合能源系统为例，根据可再生能源发电和负荷特点，选择4种典型场景，并在定向运行下进行对比分析。结果表明，虽然弹性导向比经济导向增加了运行成本，但在无外网情况下，4种情景下的减载率分别降低了44.84%、30.26%、48.49%和34.37%。研究了弹性导向权重系数和氢气价格变化对系统弹性性能的影响，为决策者提供更多参考。

期刊介绍： Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
