Abstract：In this paper, for the study of voltage stability of DC micro-grid under droop control, build a DC micro-grid simulation model includes AC/DC rectifier and DC/DC converter, based on which the small signal stability of DC micro-grid is analyzed to obtain the eigenvalues of system when different droop factor is taken. Numerical results show that DC micro-grid which sets reasonable controller parameters and filter parameters remains stable when takes a larger droop factor. To further verify the validity of analytical methods, the time-domain simulation test based on DC micro-grid was implemented to demonstrate the correctness of the small signal stability analysis.
