Method for controlling a power supplied to an electrical network, with hybridization controller

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.
