1. A method for controlling the power distribution in a hybrid propulsion system including at least one electrical power source delivering an AC voltage associated with a controlled AC/DC rectifier and at least one battery, wherein the controlled AC/DC rectifier and the battery are each directly connected to an HVDC DC bus powering at least one electrical load, the control of the power distribution is performed through the controlled AC/DC rectifier on its own by a regulation loop on a power setpoint based on a measured power of the battery and a regulation loop on a voltage setpoint based on a measured voltage of the HVDC bus, one or the other of these two regulation loops each delivering a quadratic current setpoint Idref and Igref for a regulation loop based on a current of the electrical power source delivering an AC voltage, wherein the quadratic current setpoint Igref is selectively delivered by one or the other of the two regulation loops on the power or voltage setpoints, according to a hybrid rating of the hybrid propulsion system for one of them and one of the thermal or start-up ratings of the hybrid propulsion system for the other.
