Fault Ride-Through for Hydrogen Electrolyzers

2025 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 ...

Fault coordination control for converter-interfaced sources compatible with differential protection during asymmetrical faults

Energy Reports, 2022
Converter-interfaced renewable energy sources (CIRESs) may have a different fault current angle with synchronous generators (SGs), so the large angle difference on both sides will cause low sensitivity or failure for traditional proportional braking ...
