介绍了研究大型氢电解槽快速频率响应的建模基础。具体来说,我们提出了一个动态模型的HE电解堆,电力电子接口,下游氢过程的操作约束,这是适合系统级的频率动态研究。然后,我们建模和研究HE FFR依赖于应急前的操作点,大小,转换器的过载能力,网络位置,和有源功率频率控制器。通过对2030年可再生能源占50%的情景以及2018年8月分离事件的动态模拟,在澳大利亚多区域测试系统上进行了不同的案例研究。我们的建模和结果说明了电网规模的HE如何支持低碳系统更安全和更有弹性的运行,以应对可靠和极端的停电以及不同设计设置和运行条件和限制的作用。
This paper introduces the modelling foundations to study the fast frequency response (FFR) from utility-scale hydrogen electrolyzers (HEs). Specifically, we propose a dynamic model of the HE electrolysis stack, power-electronics interface, and downstream hydrogen process operational constraints, which is suitable for system-level frequency dynamics studies. We then model and study HE FFR dependency on pre-contingency operating point, size, converter's overloading capability, network location, and active power-frequency controller. Different case studies are run on the Australian multi-area test system via dynamic simulations of a 2030 scenario with 50% renewables and in the context of the August 2018 separation event. Our modelling and results illustrate how grid-scale HEs could support a more secure and resilient operation of low-carbon systems for both credible and extreme outages and the role of different design setups and operating conditions and constraints.
