Abstract: It stands out mainly for consisting of a nested configuration of electrolysis units (5), independently operated, the nominal power values of which are descendant in such a manner that, for any unit of the system, the sum of the nominal power of the smaller electrolysis units (5) is always greater than or equal to the “dead band” (DB) of said units, allowing reduction of the dead band of said hydrogen production system (4) to negligible levels, avoiding loss or discharge of the energy generated in said renewable power stations, preferably one or several wind farms (2) formed by a group of wind turbines (1), connected to the power grid (3) as a consequence of the implementation of a primary control service therein or, in general, of any other active power control service, thereby optimizing the total energy obtained.
