英文摘要：

There are a lot of power converters in DC microgrid and they are presented as constant power loads in the close-loop control,which may cause the stability problem. A method of DC microgrid stabilization based on linear state feedback is proposed,which introduces a linear state feedback branch to counteract the impact of constant power loads,ensuring the stable operation of whole DC microgrid.Simulative and experimental results verify the feasibility and effectiveness of the proposed method.
