| contents | Restricting bus voltage deviation is crucial for normal operation of multi-bus DC microgrids, yet it has received insufficient attention due to the conflict between two main control objectives in DC microgrids, i.e., voltage regulation and current sharing. By revealing a necessary and sufficient condition for achieving these two objectives, this paper proposes a compromised distributed control algorithm, which regulates the voltage deviation of all buses by relaxing the accuracy of current sharing. Moreover, for a class of DC Microgrids consisting of both critical nodes and ordinary nodes, this paper proposes a distributed control algorithm that restricts the voltage deviation of critical nodes and simultaneously keeps the current sharing of ordinary nodes. This algorithm also works under plug-and-play settings. Simulations illustrate our theory. |
