This paper proposes a novel distributed control for time-delayed DC MGs to achieve accurate current proportional sharing and weighted average voltage regulation. Firstly, by utilizing an advanced observer based on the PI con-sensus algorithm, the steady-state bias problem is. . For cooperation among distributed generations in a DC microgrid (MG), distributed con-trol is widely applied. However, the delay in distributed communication will result in steady-state bias and the risk of instability.
