Abstract: Current sharing and voltage regulation in multi-bus DC microgrids are two fundamental control objectives, between which there is a tradeoff due to their conflicting nature.
In, the authors propose a distributed secondary control scheme to maintain voltage stability in DC microgrids without compromising load current sharing performances. Master–slave control and droop-based control are two common primary-level strategies employed to ensure stable operation in parallel-connected DG units.
Scientific Reports 14, Article number: 30195 (2024) Cite this article 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.
To overcome this issue, an enhanced power sharing control method is proposed in this paper to address load sharing in parallel-connected DG units based DC microgrids, considering unmatched line impedance and load variation.
Traditional droop control methods are difficult to achieve accurate and autonomous current sharing between micro-source …
