Fault Ride-Through for Hydrogen Electrolyzers

open access: yes2025 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe)
Abstract: This paper investigates the Fault Ride-Through (FRT) capability of a Proton Exchange Membrane (PEM) electrolyzer system supported by Supercapacitor (SC) energy storage under symmetrical fault conditions. Three configurations are analyzed: a baseline case without SC integration, SCs directly connected to the DC link, and SCs interfaced via a ...
