摘要

Procedure for controlling the electrical power delivered in an electrical network by at least two sources (16) of electrical energy, each source (16) of energy being connected to the network (20) and comprising an energy storage organ (22) electrical, the procedure for each energy source (16) comprising the following steps: - the application (104; 204) by the power source (16) of an alternating voltage signal (S1ij) in the electrical network (20) for the mains power supply, having a parameter of the voltage signal (S1ij) a predetermined initial value, - the measurement (106; 206) of an electric power (Pij) associated with the applied voltage signal (S1ij), - the determination (108; 208) of an electric energy (ESij) stored in the storage organ (22), - the calculation (112; 214) of a setpoint value (Aij or Fij) of the voltage signal parameter in function of the measured power, - the modification (114 ; 216) of the voltage signal, the value of the parameter of the voltage signal being modified to be equal to the setpoint value (Aij, Fij) calculated, characterized in that during step (112; 214) of calculation, the setpoint value (Aij, Fij) is also calculated based on the determined stored electrical energy (ESij) and is a decreasing function of the electrical power (Pij) and an increasing function of the energy (ESij) stored electricity, because each energy source is adapted to deliver a maximum power (Pnj) to the network (20) and so that the parameter of the voltage signal is greater than a minimum operating value (Amin or Fmin), and because , for each energy source (16), during the calculation stage (112; 214), the setpoint value (Aij or Fij) is equal to the minimum operating value (Amín or Fmin) when the measured electrical power (Pij) It is equal to the maximum power (Pnj).
