Abstract
The invention relates to a method for controlling an electrical microgrid (1) comprising a renewable power source (3), delivering, to the microgrid (1), a first power that is controlled by droop control, and capable of synchronously operating in parallel with a synchronous power source (2), the synchronous source (2) being capable of generating a second power that is also delivered to the microgrid (1), according to a criterion for the automatic start/stop of said synchronous power source, the method comprising the starting of the synchronous source as soon as the frequency and/or the voltage of the microgrid (1) are lower than a threshold frequency and/or a threshold voltage, respectively, and the stopping of the synchronous source as soon as the second power is lower than a threshold power.
