Plug-and-Play (P&P) performance facilitates the modularity of DC microgrids. The realization of P&P operation relies on the control design of DC microgrids. Conventional control methods are normally designed for steady operation of a DC microgrid, neglecting or partially sacrifices the availability of P&P operations. Some bottom layer’s control designs such as droop control, from a hierarchical control scheme perspective for example, are inherently able to realize P&P operations. However, such methods have limitations in terms of power sharing accuracy. This paper proposes a control scheme that reconfigures hierarchical control and makes it more compatible for different P&P operation situations in DC microgrids. In this control scheme, Automatic Mater-Slave (AMS) control is implemented in the secondary control layer to automatically respond to those cases in the absence of communication or the failure of the master module. The proposed control scheme is validated by MATLAB/Simulink simulation.
