Microgrid master-slave control feedback joint
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. . The improved V/f control strategy is composed of two parts, feedforward compensation and robust feedback control. The design of the feedforward compensator is realised by the method of approximate full compensation. In this method, the master source of each MG broadcasts its relative power loading as a common signal to the slave sources of the same MG and IC through a unidirectional low-bandwidth. .
