Centralized communication-based control is one of the main methods that can be implemented to achieve autonomous advanced energy management capabilities in dc microgrids. However, its major limitation is the fact that communication bandwidth and computation resources are limited in practical applications. This can be often improved by avoiding redundant communications and complex computations. In this paper, an autonomous communication-based hybrid state/event driven control scheme is proposed…

TLDR
With the proposed control strategy, the power transmitted between the converter and the DC bus can be quickly reduced to zero in the case of mode transition between operating modes, such as cutting off a converter or pitching in a converter, avoiding voltage shock and achieving seamless transition.
