A new power flow control approach for power converters in single-phase microgrids

摘要

This paper presents a novel control technique for power converters used in single-phase Microgrids (MGs). The proposed control scheme can control the voltage and frequency of the MG while regulating the DC-bus voltage of the power converter. The proposed controller can significantly improve the transient performance of the system while providing a very fast and accurate MG parameters regulation and power sharing. The superior transient performance is due to the fact that, the DC-bus dynamics is embedded in the proposed control system, which enhances the control of input and output parameters (e.g., voltage, frequency, power, etc.). The simulation and experimental results confirm the superior performance of the proposed controller in regulating various parameters in comparison with the conventional proposed droop-based controllers.
