Abstract
Cascaded H-bridge topology has been used in grid-tied converter for battery energy storage system due to its modular structure. To fully utilize the converter’s modularity, we propose a hierarchical distributed control architecture that consists of primary control and secondary control. Primary control ensures correct current tracking, but may lead to unequal power output among modules. A distributed secondary control based on consensus algorithm is presented to establish equal power sharing among modules. Further, a carrier phase shift control is implemented to achieve multilevel output voltage and harmonic reduction. Finally, the effectiveness of the presented control strategy is verified through experiments.
