6 FAQs about [Microgrid master-slave control]

What are the control modes of a master-slave microgrid?

For the master–slave microgrid shown in Fig. 1, the master inverter has two control modes, namely P / Q and v / f control modes. When the STS is closed,the microgrid operates in grid-connected mode.

How DG inverters work in a master-slave microgrid?

In a master–slave microgrid, all the DG inverters are working in P / Q control mode when 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 references to the P / Q -controlled slaveinverters.

What control structures do microgrids use?

There are two control structures for the islanded operation of microgrids: peer-to-peer control and master–slave control.

What is a master slave power supply?

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 to achieve the power balance of the microgrid.

What is a master-slave control method?

To realize these objectives, a new coordinated control based on master–slave approach is proposed in this paper. 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 communication network.

Can a Master inverter achieve seamless modetransfer between grid-connected and autonomous islanding modes?

This study proposes a simple mixeddroop- v / f control strategy for the master inverter of a microgrid to achieve seamless modetransfer between grid-connected and autonomous islanding modes.
