This contribution presents control methods for the regulation of the voltage and the frequency on AC minigrids, fed by voltage source inverters (VSI). In order to avoid a complex communication network for the synchronization of the various VSI on a minigrid, a conventional method called “Droop Control” consists in the emulation of rotating alternators for each VSI. Then the VSIs generate AC voltages with an active power dependent frequency, and a reactive power dependent voltage. Such a method is presented and simulated on a given minigrid. A second less-conventional method is introduced, where the characteristics on the minigrid line impedances are taken into account. This is obtained the projection of the active and the reactive power in a new referential depending on the line characteristics. By maintaining a “Droop Voltage” control on the new parameters, it is shown that the global stability is increased
