Control method of a virtual generator
First Claim
1. A method for controlling a virtual generator comprising at least one renewable power source, an accumulation system comprising:
- a power and/or energy reserve, an inverter and a control law, the virtual generator delivering to a microgrid an active P/reactive Q electrical power with a voltage V and a current I, said voltage V and current I having a frequency f, said active/reactive electrical power controlling, via droop control, the frequency f and the RMS voltage Vrms of the voltage V, respectively;
controlling the virtual generator via the control law for which said virtual generator carries out an adjustment of the active/reactive power delivered to the microgrid, said adjustment compensating for a variation in the active/reactive power consumed by the microgrid, wherein the accumulation system applies a DC voltage Vref to first terminals of the renewable power source so that the renewable power source delivers a power Psr, said power Psr being liable to exhibit power fluctuations, the accumulation system being controlled in order to compensate for said fluctuations, in which the voltage Vref is determined by a voltage sweep of the first output terminals, and by simultaneously measuring the amperage of the current produced by the renewable power source and said voltage Vref.
