Current Sharing of DC Microgrids by Sampled-data Input Consensus Control

— Implementation and Experimental Validation —

Abstract

In this paper, we discuss the implementation of a sampled-data input consensus controller to achieve current sharing and average voltage regulation in DC microgrids with current sources. We show that an appropriate selection of controller gains enables the sampled-data controller to be implemented using information from each node's neighbors and neighbors-of-neighbors. Experimental results are also presented to validate the effectiveness of the sampled-data input controller under the proposed gain selection.
