Experimental Validation of an Accurate Reactive Power-Sharing Approach Based on Adaptive Virtual Impedance and Consensus Control

In this paper, a hierarchical distributed controller is implemented in an AC islanded microgrid (MG). For the primary controller, a droop control method is used to share the load active and reactive power between the distributed generators (DGs). However, the reactive power can’t be shared accurately due to the line impedance mismatch. Thus, adaptive virtual impedance based on a consensus algorith...
