Abstract

The present invention relates to a method (1000-2000) of controlling an electric energy generation plant (1). The plant comprises a unit for generating electric energy from a renewable energy source (2), an electrolyzer (51) for the generation of hydrogen, a battery (8) connected to the electrolyzer (51), at least one converter (3,4) adapted to supply an available power generated by the electric energy generation unit (2) to at least one of a load and the electrolyzer (51), a control system (6) for controlling the plant (1), and input means (7). The input means are adapted to acquire at least one of input information relating to the operation of the plant (1), meteorological information of a region in which the plant (1) is located and information relating to the operation of further plants located in the vicinity of the plant (1).The method comprises that the control system performs the step of: monitoring (1002) the available power, generated by the renewable energy source (2), andwhen the available power falls below a threshold (1011), the method comprises that the control system performs the step of:estimating (1014-1017) a recovery time interval at the end of which the available power will exceed the threshold,determining (1014-1017) whether the battery is able to supply the electrolyzer (51) for said recovery time interval, and in the affirmative case, supplying (1012) the electrolyzer (51) by means of the battery (8).In particular, the step of estimating a recovery time interval comprises for estimating the recovery time interval as a function of the at least one piece of input information, wherein the input information comprises at least one among a piece of information relating to the operation of the plant (1), a piece of meteorological information of a region in which the plant (1) is located and a piece of information relating to the operation of further plants located within a predetermined monitoring radius centred on the plant (1).
