Abstract Master-Slave configuration is a common structure used in micro-grids. In this configuration, only one inverter is the master, while the others are slaves. In grid-connected mode, the master should be synchronous with the grid, and, in island mode, it serves as a reference to the slave inverters. Based on the master-slave concept, a smooth transformation control method is discussed in this paper. A novel phase-locked loop applied to micro-grids is proposed, which can ensure the smooth transformation of the two modes, and it will reduce the transient effects while switching as well as enhance the stability of the system. Finally, the simulation and experimental results are provided to verify the effectiveness and feasibility of the proposed control strategy.

Key words： Microgrids master-slave configuration phase-locked loop operation mode transition
