In the master–slave control structure, a distributed generation or energy storage device is set as the master power supply, which adopts the V/f control to provide the stable voltage and frequency for the microgrid, and coordinate other slave power supplies adopting PQ control. . In the master–slave control structure, a distributed generation or energy storage device is set as the master power supply, which adopts the V/f control to provide the stable voltage and frequency for the microgrid, and coordinate other slave power supplies adopting PQ control. . modewhen it is connected to theutility grid. However,when it is islanded,the master inverter has to switch to v /f control mode to provide voltage andfrequency refe ences to the P /Q -controlled slav ical example of a centralized control scheme. Two sources out of three use droop control as the main control source, and another is a subordinate one with constant power control which is also known as real and. . For a more in-depth analysis of the impacts of this scenario, this paper contributes with a proposal to modify the strategy for identifying possible intentional islanding. The voltage control strategy in the peer-to- peer control structure is the droop control.
