Abstract:
1. A hydrogen production system for controlling power in power stations based on renewable energy sources, comprising at least one level of two electrolysis units that are independently controlled comprising a larger electrolysis unit and a smaller electrolysis unit, the at least one level of electrolysis units being disposed in a descending nominal power configuration such that, for any level of electrolysis units, the nominal power of the smaller electrolysis unit is approximately equal to a dead band of the larger electrolysis unit, said dead band being the region in which the electrolysis unit cannot operate; wherein the hydrogen production system is continuous throughout the operating range of the system thus reducing the dead band of said hydrogen production system to a negligible value, said value being lower than the dead band of a system with a single electrolysis unit and avoiding the loss or discharge of energy generated in a grid connected to renewable power stations.
