    "description": "<p>This paper investigates the detailed elements of a DC microgrid that might cause instability, and proposes a&nbsp;stabilizing guidance based on the passive stability criterion. For illustration purpose, the terminal output impedance model of a&nbsp;source side power converter under double loop with droop control is built, and its frequency characteristics are analyzed.&nbsp;It is found that the instant high power absorption from the microgrid might make the source side power converter&rsquo;s output&nbsp;to oscillate. The details of how the circuit and control elements in the source side impact the terminal impedance are illustrated.&nbsp;This paper shows that the stability of plug and play performance of DC microgrid can be guaranteed with the proposed enstabilization methods. A Matlab/Simulink model is used to validate the analysis.</p>",
