Enhanced Reactive Power Sharing and Voltage Restoration Based on Adaptive Virtual Impedance and Consensus Algorithm

In this paper, power-sharing management control on an AC islanded microgrid is investigated to achieve accurate reactive power sharing. The droop method primarily used manage the active and sharing among DGs in microgrid. However, line impedance mismatch causes unbalanced As a solution consensus-based adaptive virtual controller proposed, where consensus algorithm set mismatch; then correction term generated through proportional-integral eliminate mismatch. Thus, achieved without knowledge of impedances or using central controller. Moreover, restore bus voltage nominal value by estimating average neighbor communication compensate for decreased magnitude reference. Matlab/Simulink validate accuracy restauration achievement proposed simulation different scenarios. addition, dSPACE DS1104 within developed experimental testbench based two parallel effectiveness real world.
