In　DC　microgrids,　the　problem　of　conflicting　bus　voltage　offset　and　distribution　accuracy　exists.　Therefore,　this　paper　proposes　a　hybrid　control　strategy　for　DC　microgrid　bus　voltage　considering　additional　inertia　adjustment.　The　control　strategy　combines　the　step-down　control　and　the　additional　control,　where　the　step-down　control　is　used　to　realize　the　DC　bus　voltage　unification,　and　the　additional　control　provides　inertia　to　the　microgrid　to　improve　the　dynamic　response　capability.　Finally,　the　proposed　strategy　is　validated　by　MATLAB/Simulink　simulation.　The　results　show　that　the　novel　control　is　able　to　improve　the　current　distribution　accuracy　degree　while　ensuring　the　bus　voltage　fluctuation,　and　at　the　same　time　effectively　improve　the　stability　of　the　DC　microgrid　in　a　wider　impedance　range.　©　2023　IEEE.
