Abstract

This paper presents a method which mimics coupled nonlinear Poincaré-Bendixson oscillators synchronization to realize current sharing in islanded three-phase Microgrid. We propose that each inverter be controlled to imitate the dynamics of coupled oscillators. When they are controlled to interact strongly enough, they will all start synchronization. We also introduce the comparison between Van der Pol oscillator corresponding to their physical characteristics. The dual-loop based on the oscillator is designed in αβ frame, and the phase dynamics are derived to observe system initial state performance. The behavior and performance of the proposed method were verified experimentally regarding load connection, inverter removal and current ratios changes.
