Application: Electrolysis device having a converter and method for providing instantaneous reserve power for an ac voltage grid (Patent ID: US20240117513A1)
The patent filed by SMA Solar Technology AG describes a method for operating an electrolysis device that involves a converter connected to an AC voltage grid and an electrolyzer. The method includes operating the electrolysis device within a specific electrical power range when the grid frequency matches the nominal frequency of the AC voltage grid. The converter is operated in a voltage-impressing manner to adjust the AC active power drawn from the grid based on changes in the grid frequency.
Furthermore, the patent outlines various claims related to the operation of the electrolysis device, including using a droop mode control for the converter, emulating the behavior of a synchronous machine, and producing voltage transformation between the electrolyzer and the converter. The method also involves exchanging electrical power with a PV generator or a battery connected on the DC voltage side, stabilizing the DC link circuit voltage, and controlling the DC/DC converters based on the phase difference between grid voltage and converter input. Overall, the patent focuses on optimizing the operation of the electrolysis device by efficiently managing power flow and responding to changes in grid frequency to ensure stable and effective electrolysis processes.
