Abstract

A highly flexible and reliable control strategy is proposed to achieve bounded voltage and precise current sharing, which is implemented in a reverse-droop-based dc Micro-Grid. To acquire the fast-dynamic response, the reverse droop control is used to replace the V-I droop control in the primary level. In the secondary level, the containment-based controller is proposed to bound the bus voltages within a reasonable range and keep the necessary voltage deviations for power flow regulation; the consensus-based controller is simultaneous involved to regulate power flow achieving accurate current sharing among converters. Combined the proposed controllers with the electrical part of the dc Micro-Grid, a model is fully developed to analyze the sensitivity of different control coefficients. Experimental results are presented to demonstrate the effectiveness of the proposed method.
