Control method for an electrolysis plant

Abstract

The present invention relates to a control method for adjusting the load of an electrolysis plant (1) by means of a central plant control system (5), wherein the plant control (5) is configured such that at a time t0, within the physical limits Lmin to Lmax of the electrolysis plant (1), a maximum available capacity Lplant of the electrolysis plant (1) for first discrete time segments of a time interval t1 to t2 can be set as a first setpoint, that at the time t0, within the maximum available capacity Lplant, the utilization of the electrolysis plant (1) Splant can be set as a second setpoint for second discrete time segments of a time interval from ta to t2, where t2 > t1 > ta ≥ t0, and wherein an electrical power or a quantity of hydrogen is specified to the plant controller (5) as the first and second setpoints.
