Microgrid Distributed Control Theory
These distributed generators that form small electrical networks called 'Microgrids' (MGs), are smaller in terms of installed power, but they are very effective in their performance. Because of the widespread use of advanced control technologies with features such as power electronics devices, detection/measurement applications, and communication infrastructures. More information can be found on the University of Groningen web ity of Groningen/UMCG research database (Pure): For technic r, where the energy price depends on the to-tal current. .

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. .
