Abstract

This paper presents grid-code considerations that must be addressed when connecting large electrolyzer plants to the electrical grid. A model for an electrolyzer module based on a grid-connected three-phase H-bridge converter is presented, together with a scaling method, for investigating relevant aspects. A low-voltage-ride-through strategy is implemented into the converter and the performance of the strategy is tested against running the system with no low-voltage-ride-through strategy. Finally, the paper will conclude on the ability of the electrolyzer plant to provide reactive power support and the considerations that must be made if this support is desired.
