An effective bus voltage stability control strategy is an extremely important guarantee for the stable and safe operation of DC microgrids in complex environments. This paper takes a small DC microgrid as the research object. Based on the switchboard＇s DC bus voltage as the control signal, the DC microgrid bus voltage control strategy and simulation research for the segmented regulation bus voltage of each inter- face grid-side converter are established. The results show that the DC microgrid bus voltage control strate- gy based on the switching table can realize the stable operation of the DC microgrid bus voltage,and ensure that the system can work stably under islanding,grid-connected and other operating environments. The re- search results have practical value for ensuring the stable and safe operation of DC microgrids in complex environments.
