A Current-Sharing Method Based on Networked Control for Three-Phase Parallel Inverter

In this paper, a simple networked control strategy of current-sharing for three-phase inverter parallel operation is proposed, which makes full use of network data to achieve relatively good performance without increasing complexity of system. Different with the master-slave mode, the communication architecture is built by autonomous mode and thus ensuring the inverters can share the power information between each inverters. The comparative description is embarked with the droop-only method and it shows that the superior performance of current-sharing for parallel operation can be realized. The experimental results demonstrate the validity of these schemes and the analysis.
