Basic Research on Microgrid switching method

2020 
This paper proposes a seamless transfer method of microgrid in grid connected and islanded mode based on the master-slave control strategy considering the variety of distributed generations. The control model is also illustrated. The problem of power deficit during islanded operation can be solved by power error calibration in slave control. The proposed master-slave seamless transfer method of microgrid between grid-connected and islanded operation modes was simulated based on DIgSILENT software. The simulation results verified the effectiveness of proposed control method.
