production, by the hybridization controller, of a power setpoint for the battery energy storage system; production, by the hybridization controller, of a substitution signal representative of the power to be supplied by the electrical production plant alone; and acquisition, by a plant controller comprising an input for acquisition of a signal representative of the power to be supplied by the electrical production plant, of said substitution signal. ## Claims ### Claim 1 A method for controlling a power supplied to an electrical network having a rated frequency, by an electrical production set comprising an electrical production plant and a battery energy storage system, the method comprising: acquiring a first signal representative of the power to be supplied to the electrical network; acquiring a second signal representative of a state of a charge of the battery energy storage system; controlling the electrical production plant and controlling the battery energy storage system, so as to supply the power to the electrical network as a function of the acquired first signal and of the acquired second signal, wherein the acquiring of the first signal is performed by a hybridization controller comprising an input for acquisition of a signal representative of the power to be supplied to the electrical network, and the method further comprises determining, by the hybridization controller, the power relative to the electrical production plant, and to the battery energy storage system; producing, by the hybridization controller, a power setpoint for the battery energy storage system; producing, by the hybridization controller, a substitution signal representative of the power to be supplied by the electrical production plant alone; acquiring, by a plant controller, which includes an input for acquisition of a signal representative of the power to be supplied by the electrical production plant alone, said substitution signal; and producing, by the plant controller, setpoints for production members of the electrical production plant. ### Claim 2 (depends on 1) The method according to claim 1, wherein the first signal and the substitution signal are of a same nature. ### Claim 3 (depends on 2) The method according to claim 2, wherein the first signal is a frequency of the electrical network and the substitution signal is a hypothetical electrical network frequency. ### Claim 4 (depends on 1) The method according to claim 1, further comprising filtering the first signal to extract therefrom a low-frequency component, a frequency of which is lower than a predetermined threshold, the substitution signal being produced at least from said low-frequency component. ### Claim 5 (depends on 4) The method according to claim 4, wherein the filtering step further comprises determining a difference between the frequency of the electrical network and the rated frequency. ### Claim 6 (depends on 5) The method according to claim 5, wherein, in the filtering step, the filtering is applied to a signal made up of the continuous acquisition of said difference between a frequency of the electrical network and the rated frequency. ### Claim 7 (depends on 6) The method according to claim 6, wherein the value of the rated frequency of the electrical network is combined with said low-frequency component to produce the substitution signal. ### Claim 8 (depends on 4) The method according to claim 4, wherein the filtering step is performed by a low-pass filter, the cut-off frequency of which corresponds to said predetermined threshold. ### Claim 9 (depends on 8) The method according to claim 8, wherein the low-pass filter has a time constant corresponding to approximately one third of a time constant of the electrical production plant. ### Claim 10 (depends on 4) The method according to claim 4, further comprising producing, by the hybridization controller, a signal relating to management of the charge of the battery energy storage system, said signal being combined with said low-frequency component, to produce the substitution signal. ### Claim 11 (depends on 10) The method according to claim 10, wherein the signal relating to the management of charge of the battery energy storage system relates to a target state-of-charge parameter of the battery energy storage system. ### Claim 12 (depends on 1) The method according to claim 1, wherein, in the step of producing the power setpoint for the battery energy storage system, the hybridization controller determines an electrical frequency stabilization power corresponding to the substitution signal. ### Claim 13 (depends on 12) The method according to claim 12, wherein, in the step of producing the power setpoint for the battery energy storage system, the hybridization controller determines, from the first signal, an expected total electrical network frequency stabilization power. ### Claim 14 (depends on 13) The method according to claim 13, wherein the power setpoint for the battery energy storage system is produced from a difference between said expected total electrical network frequency stabilization power and said electrical frequency stabilization power corresponding to the substitution signal. ### Claim 15 (depends on 1) The method according to claim 1, further comprising a deactivating the battery energy storage system, in which the hybridization controller produces the substitution signal which reproduces the acquired first signal.
