Optimizing power sharing accuracy in low voltage DC microgrids considering mismatched line resistances.

The main difficulties facing the operation of parallel converters in DC microgrids (DCMGs) are load sharing, circulation current, and bus voltage regulation. A droop controller is commonly used to control current sharing among parallel DC-DC converters due to its simplicity. However, the values of droop parameters impact both bus voltage regulation and the error in current sharing among converters.
