Hydrogen production system for controlling the power output of power stations based on renewable energhy sources and control process

Abstract

It stands out mainly for consisting of a nested configuration of electrolysis units (5), independently operated, the power output values of which are descendant in such a manner that, for any unit of the system, the sum of the power output values 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 optimising the total energy obtained.
