英文摘要	The voltage stability detection based on impedance-ratio criterion is introduced into the DC microgrid with wind power, a small-signal model of DC microgrid with wind power is established and analyzed, and the expressions of output/input impedance is derived for each element. A small-signal control model in two-phase synchronous rotating coordinates system is derived in detail for wind-power element and the influences of key parameters on the DC-side output impedance is analyzed, such as bus voltage, cross-over frequency, etc., based on which, the impedance-ratio models are built for DC micro-source and load sub-system to simulate and analyze the stability of cascading system. Simulative results show that the proposed method of stability analysis based on small-signal impedance ratio can be used to guide the design of DC microgrid with wind power. © 2017, Electric Power Automation Equipment Press.
