  • Publication number: 20230283077
    Abstract: A method for controlling power supplied to an electrical network having a rated frequency, by an electrical production set with a hydroelectric plant and a battery energy storage system, includes determining, from a model of the hydroelectric plant, a theoretical power of stabilization of the frequency of the electrical network by the hydroelectric plant, the theoretical stabilization power being relative to a production of the hydroelectric plant alone for the stabilization of the frequency of the electrical network, when setpoints for production members of the hydroelectric plant are implemented.

  • Publication number: 20230275431
    Abstract: 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, comprises acquisition, by a hybridization controller, of a first signal representative of the power to be supplied to the electrical network; 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.

  • Publication number: 20220011374
    Abstract: A method for determining an ageing function of an accumulator, the ageing function representing a variation in the capacity or resistance of the accumulator, as a function of variables representative of the operation of the accumulator, the method including carrying out a plurality of experimental cycles of charging and discharging a test accumulator, each cycle being parameterised by accumulator operating parameters that vary as a function of time during the various cycles; b) during experimental cycles, determining experimental data, including a value of each variable parameter, and determining the capacity or the resistance; c) on the basis of the experimental data resulting from b), determining the ageing function of the accumulator; wherein in step a), the variable parameters include the state of charge and a depth of discharge, such that, following step c), the variables of the ageing function with the state of charge and the depth of discharge.

  • Patent number: 9759776
    Abstract: A method of determining the state of health of a first elementary cell of a battery, including the steps of: measuring the voltage across the cell under a reference current at a plurality of times in a phase of cell charge or discharge between first and second state-of-charge levels; and detecting a crossing by the voltage of a predetermined specific value, corresponding to a predetermined specific charge value of the cell.
