hydrogen production system to control output power in power plants based on renewable energy sources; process for controlling the power supplied to the grid and the frequency of the grid at its nominal value using said system; output and access power control process for controlling reactive power exchange with the grid for power plants based on renewable energy sources

摘要

The invention relates to a system that is essentially comprised of a hierarchic configuration of independently operated electrolysis units (5) the power levels of which descend in such a way that, for any unit in the system, the sum of the power of the smaller electrolysis units (5) is always greater than or equal to the "deadband" (DB) of said unit, enabling the deadband of said hydrogen production system (4) to be reduced to negligible levels, avoiding the loss or discharge of energy produced in said renewable energy plants, preferably one or more wind parks (2) consisting of a series of wind turbines (1) connected to the electric grid (3) as a result of the implementation of a primary regulation service thereof, or in general, of any other active power regulation service, thus optimizing the total energy obtained.
