Abstract

Nowadays, multi-energy supply utility grid system has witnessed the destruction of increasing natural disasters. Under the disasters, the energy supply capability from the utility grid system to the end-user microgrids is decreased, which is due to the destruction of the system infrastructure. Thus, how to improve the resilience of the microgrids under disasters is an essential problem. In this paper, a mobile hydrogen truck-assisted methodology is proposed to deliver hydrogen tanks to end-user microgrids via transportation network to resist to the natural disasters. First, a temporal–spatial destructive model of the natural disasters based on the grid division is presented, and the dynamical energy supply ability of an IEEE30+gas20+heat14 utility grid system is derived. Second, a hydrogen tank delivering model from hydrogen company to microgrids based on transportation network is presented. Third, a real-world transportation network based on SUMO simulator is linked with Matlab to simulate the real-time coupling between transportation network and power network. Last, microgrids optimal operation based on the temporal–spatial destructive model and hydrogen tank delivering model is presented. The simulation results show that with the assistance of the arrived hydrogen tanks through real-world transportation network in microgrid, one can indeed reduce load shedding. However, when considering the damaged transportation network, the saving loads are reduced due to the increase of the mobile hydrogen storage delivery time. It reveals that delivering mobile hydrogen tanks to end-user microgrids can effectively improve the system resilience.

基于交通网络的移动氢能卡车提高多能源供应微电网弹性

目前，多能源供电公用电网系统受到越来越多的自然灾害的破坏。在灾害条件下，由于系统基础设施的破坏，电网系统向终端用户微电网的供能能力下降。因此，如何提高微电网在灾害条件下的恢复能力是一个至关重要的问题。本文提出了一种移动氢车辅助的方法，通过运输网络将氢罐运送到终端用户微电网，以抵御自然灾害。首先，建立了基于网格划分的自然灾害时空破坏模型，推导了IEEE30+gas20+heat14公用电网系统的动态供能能力。其次，提出了基于交通网络的氢能公司向微电网输送氢罐的模型。第三，将基于SUMO模拟器的现实交通网络与Matlab相结合，模拟交通网络与电网的实时耦合。最后，提出了基于时空破坏模型和氢罐输送模型的微电网优化运行。仿真结果表明，在微电网实际运输网络中到达的氢罐的辅助下，确实可以减少减载。然而，考虑到运输网络的损坏，由于移动储氢交付时间的增加，节省的负荷会减少。研究表明，向终端用户微电网提供移动氢罐可以有效提高系统的弹性。

期刊介绍： eTransportation is a scholarly journal that aims to advance knowledge in the field of electric transportation. It focuses on all modes of transportation that utilize electricity as their primary source of energy, including electric vehicles, trains, ships, and aircraft. The journal covers all stages of research, development, and testing of new technologies, systems, and devices related to electrical transportation. The journal welcomes the use of simulation and analysis tools at the system, transport, or device level. Its primary emphasis is on the study of the electrical and electronic aspects of transportation systems. However, it also considers research on mechanical parts or subsystems of vehicles if there is a clear interaction with electrical or electronic equipment. Please note that this journal excludes other aspects such as sociological, political, regulatory, or environmental factors from its scope.
