A method for driving an electricity production assembly includes an electricity production system, that generates an output power, as well as an electricity storage system. The production assembly is driven, at each time-step, in such a way as to deliver a total power that is less than a maximum admissible power. The maximum admissible power is determined in such a way that the production assembly can, starting from this power, and taking account of a stored energy in the storage system at the considered time-step, progressively reach, with a moderate slope, a minimum anticipated power, which is representative of the worst downward variation expected for the output power in case of degradations in meteorological conditions.
