Abstract

Electrolysis system comprising an electrolysis plant and a renewable power generation plant and method for controlling an electrolysis system. The present invention relates to an electrolysis system (100) comprising a renewable power generation plant (1) and an electrolysis plant (3) that both are connected to a common AC bus bar (5), wherein the electrolysis plant (3) comprises a rectifier (7) whose AC input (9) is connected to the AC bus bar (5) and whose DC output (11) is arranged to supply DC current to operate an electrolysis process, and wherein an inverter-based energy storage system (13) with a storage unit (15) and a storage controller (17) is provided, the storage unit (15) being implemented in parallel to the electrolysis plant (3) and connected to the AC bus bar (5), and the storage controller (17) being configured to control the active power (P<S>) of the storage unit (15) in such a way that the operation of a synchronous generator is emulated to stabilize the AC input voltage. The invention further relates to a method for operating an electrolysis system.
