Abstract

Master-Slave configuration is a suitable alternative to droop control method used in microgrids. In this configuration, only one inverter is the master, while the others are slaves. The slave inverters are always current controlled whereas the master inverter should have two selectable operation modes: current controlled, when the microgrid is connected to the grid; and voltage controlled, when it is operating in island mode. In gridconnected mode, the master needs a synchronization system to perform the accurate control of its delivered power, and, in island mode, it needs a voltage reference oscillator that serves as a reference to the slave inverters. Based on the master-slave concept, this paper proposes a single system that perform both functions, i.e., it can act as a synchronization system or as a voltage reference oscillator depending on an input selector. Moreover, the system ensures a smoothly transition between the two operation modes, guaranteeing the safety operation of the microgrid. Experimental results are provided to confirm the effectiveness of the proposed system. Peer Reviewed
