Method for Controlling Operation of an Electrolyzer Plant

A system for controlling operation of an electrolyzer plant, the system comprising a processing system configured and operating for:

• (a) using a first model to determine first operating points of the electrolyzer plant for a predetermined first period of time;
• (b) using a second model to simulate operation of the electrolyzer plant for the first operating points for a predetermined second period of time that is shorter than and comprised in the first period of time, the second model being a model having higher prediction accuracy for the operation of the electrolyzer plant than the first model;
• (c) determining whether the simulated operation meets a predetermined requirement;
• (d) upon determining that the simulated operation does not meet the predetermined requirement, adjusting one or more parameters and/or one or more boundary conditions of the first model, and
• (e) upon determining that the simulated operation meets the predetermined requirement, setting the first operating points as target operating points for the predetermined second period of time.
