There are major discussions worldwide, and particularly in Australia, as to how production of clean fuels, such as hydrogen, from renewable electricity could facilitate whole-energy system decarbonization. There exist, in fact, great synergies between grid integration of renewable energy sources (RES) and hydrogen production. However, RES is also driving power systems into low-inertia conditions, which might raise frequency stability challenges. Potential consequences include frequency-related outages, such as under-frequency load shedding and/or photovoltaic trip. These frequency instability phenomena may combine with severe changes in active power flows through system interconnectors, which can potentially result in interconnectors’ trip and system split, thereby threatening system resilience too.

This talk presents the capabilities of hydrogen electrolysers in provision of fast frequency response, contingency frequency control ancillary services (FCAS), regulation FCAS, and virtual inertia response, while highlighting the associated technical challenges. This presentation includes modelling foundations and simulation results to illustrate how utility-scale electrolysis plants could support a secure and resilient operation of low-carbon grids for both credible and extreme events, and the role of different converter control design setups and operating conditions and constraints.
