Real-Time Simulation of an Electrolyzer with a Diode Rectifier and a Three-Phase Interleaved Buck Converter

In this work, we implement an electrical equivalent model of a water electrolyzer in a real-time simulation environment. To power the electrolyzer, a chopper-rectifier with passive filter (CRPF) and a 3-phase interleaved buck converter (IBC) are implemented. We further analyze the performance of the electrolyzer when it is used for primary frequency control. At the end, we integrate the electrolyzer model into our campus digital twin to evaluate its real-time simulation compatibility and performance. The simulations are executed on an OPAL-RT real-time simulator.
