论文摘要
将氢存储融入具有高可再生渗透水平的电网中一直越来越兴趣。经济利益和电网可靠性对于氢存储整合都是必不可少的。在本文中，提出了一个年度能源轮毂（EH）耦合电网的调度模型（ASM），以研究季节性氢存储（SHS）的年度益处。每个能量轮毂都由氢，电解器和燃料电池组成。电气和氢能可以与能量轮毂在总线上交换。网格和EHS的物理限制在ASM中均受到实施。拟议的ASM考虑了EH耦合网格的季节内每日操作。 ASM中使用了四个典型的每日轮廓来表示四个季节的网格条件，从而减轻了计算负担。此外，季节内和跨季节氢交换和存储都在ASM中建模。因此，氢存储的利用在全年水平上进行了优化。数值模拟是在IEEE 24总线系统上进行的。模拟结果表明，季节性氢存储可以有效节省年度运营成本并减少可再生能源。
There has been growing interest in integrating hydrogen storage into power grids with high renewable penetration levels. The economic benefits and power grid reliability are both essential for hydrogen storage integration. In this paper, an annual scheduling model (ASM) for energy hubs (EH) coupled power grids is proposed to investigate the annual benefits of seasonal hydrogen storage (SHS). Each energy hub consists of hydrogen storage, electrolyzers, and fuel cells. The electrical and hydrogen energy can be exchanged on the bus with the energy hub. The physical constraints for both grids and EHs are enforced in ASM. The proposed ASM considers the intra-season daily operation of the EH coupled grids. Four typical daily profiles are used in ASM to represent the grid conditions in four seasons, which reduces the computational burden. Besides, both the intra-season and cross-season hydrogen exchange and storage are modeled in the ASM. Hence, the utilization of hydrogen storage is optimized on a year-round level. Numerical simulations are conducted on the IEEE 24-bus system. The simulation results indicate that seasonal hydrogen storage can effectively save the annual operation cost and reduce renewable curtailments.
