Systems and methods for operating electrolyzers

A hydrogen production system comprising:

• a hydrogen production facility comprising a plurality of electrolyzer units;
• a controller in communication with the hydrogen production facility;
• and
• memory having instructions stored therein executable by the controller to operate the hydrogen production facility, the instructions comprising:
• receiving an instruction signal indicating an available power level;
• determining availability states of electrolyzer units in the hydrogen production facility to determine a number of available electrolyzer units;
• determining an available load at which each of the available electrolyzer units is capable of operating relative to a base load;
• determining a base group of available electrolyzer units having available loads available to consume less than the available power level;
• determining a trim group of available electrolyzer units to consume any remaining power of the available power level not consumed by the base group of available electrolyzer units;
• and
• operating electrolyzer units of the base group of available electrolyzer units and the trim group of available electrolyzer units to produce hydrogen.
