A method for determining parameters of a simplified model of an energy storage system, including an energy storage device and a conversion device, the system being modelled by a complex model including models of the energy storage and conversion devices; the complex model receiving a setpoint power Pand a state of charge SOCat input and providing the state of charge SOC of the storage device and the power Pat the output of the storage device at output; the method including implementing simulations of the energy storage system using the complex model; calculating (a) a table of the variation in the state of charge of the system as a function of the setpoint power and of a state of charge, (b) a table of maximum power as a function of the state of charge; (c) a table of minimum power as a function of the state of charge.

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.
