Abstract
The present invention describes a process for controlling the active power injected into the grid by a generating plant for contributing to the stability of the power grid in the event of frequency variations where, in response to a deviation in grid frequency, each generating unit calculates an active power variation parameter generated based on a first parameter stored in said generating unit, said first parameter being representative of a respective contribution of said generating unit to a required variation in total active power of the generating plant, and where a central control unit of the generating plant connected to each generating unit updates the value of the first parameters when changes are produced therein.
