Reactive power sharing in microgrid using virtual voltage

The traditional droop control strategy has been applied previously in microgrids (MGs) to share accurately the active power. However, some cases result obtained when sharing reactive power is not best, because of parameters related distances from distributed generators (DGs) loads and variations. Therefore, this paper proposes a for low voltage MG, where unequal impedance between requires adjustments work with conventional frequency methods. Thus, an additional coefficient calculated network that relate location elements. test perfomed by simulations MATLAB-Simulink software, considering three-node MG three DGs load can change at different periods time. results show it possible improve located according changes simulated voltages method.
