摘要

氢储能是能源转型的一个关键方面。利用燃料电池,储存的化学能可以再次转化为电能。与电池储能相比,燃料电池的优点是能量密度明显更高。此外,储氢容器的尺寸可以独立于燃料电池本身,这简化了系统设计。然而,燃料电池的一个典型问题是缓慢的动态行为。对于瞬变快的系统,通常需要辅助电源,这反过来又使系统设计复杂化。本文提出了一种基于给定负载分布的辅助电源尺寸确定方法。然后将该算法应用于三个工业案例研究,从而突出了应用程序之间的巨大差异。

Dimensioning Lithium-ion Battery Packs and Fuel Cells for Hybrid Power Systems
Energy storage using hydrogen is a key aspect of the energy transition. By means of fuel cells, the stored chemical energy can be converted again to electrical energy. Fuel cells have the advantage that the energy density is significantly higher, when compared to battery energy storage. Furthermore, the hydrogen storage container can be sized independently from the fuel cell itself, which simplifies the system design. However, a typical problem with fuel cells is the slow dynamic behaviour. For systems with fast transients, typically an auxiliary power source will be required, which in turn complicates system design. This paper presents a methodology to dimension the auxiliary power source based on a given load profile. The algorithm is then applied to three industrial case studies, thereby highlighting large differences between the applications.
