摘要： A method for controlling a DC/AC converter connected to an electrical network, the converter being controlled by a control law that is configured to require the converter to operate, by default, in a current source mode, and in case of disappearance of the electrical network, to control the switching of said converter from the current source mode to a virtual synchronous generator mode, the control law being also configured to, as long as the converter is running in the current source mode, monitor the electrical network frequency and phase allowing the initialization of the emulation of the virtual synchronous generator mode, by said control law, at the time of detection of the disappearance of the electrical network.

摘要： A method for controlling a virtual generator including at least one renewable power source, an accumulation system including a power and/or energy reserve, an inverter and a control law, the virtual generator delivering an active P/reactive Q electrical power of voltage V and of current I to a microgrid, the voltage V and current I having a frequency f, the active P/reactive Q electrical power controlling, via droop control, the frequency f and the RMS voltage Vrms of the voltage V, respectively, the method including control of the virtual generator via the control law for which it carries out an adjustment of the active P/reactive Q power delivered to the microgrid, the adjustment being capable of compensating for a variation in the active/reactive power consumed by the microgrid.
