Control of Three-phase Four-leg Micro-grid Inverter in Islanding Mode

Off-grid operation is one of the significant characteristics of micro-grid. In off-grid mode, unbalanced loads will cause voltage unbalance and degrade the performance of micro-grid. By using a voltage closed-loop control strategy in positive and negative sequence synchronous rotating frames, load v...

description Off-grid operation is one of the significant characteristics of micro-grid. In off-grid mode, unbalanced loads will cause voltage unbalance and degrade the performance of micro-grid. By using a voltage closed-loop control strategy in positive and negative sequence synchronous rotating frames, load voltages are regulated for a three-phase four-leg micro-grid inverter. The three-dimensional space vector modulation is adopted to increase the utilization of DC link voltage. A test rig is established to verify the validity of the control strategy. Both simulation and experimental results are provided to demonstrate that the strategy can correct load voltage and improve the voltage quality under unbalanced loads in islanding mode.
