Abstract

The load power sharing and voltage quality are more challenging in islanded microgrids with nonlinear loads. Distributed generations (DGs) can be used to improve the power quality in the microgrids. However, the conventional droop control can cause poor harmonic power sharing among the DGs due to mismatched line impedance. This paper proposes a harmonic power-sharing control method using the adaptive regulation of the virtual harmonic impedance. Consensus algorithm is used to adaptively regulate the virtual harmonic impedance with consideration of mismatched line impedance. The consensus-based distributed control does not require prior knowledge of the line impedance. Simulation results are presented to demonstrate the proposed method in achieving accurate harmonic power sharing while reducing the voltage distortion at the point of common coupling (PCC).
