6 FAQs about [Microgrid master-slave control feedback joint]

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.

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.

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.

Can a two-layer control structure maintain voltage stability of a microgrid?

Based on the basic structure, a two-layer control structure is proposed in [ 21 ], which can maintain voltage stability of the islanded microgrid and also compensate the unbalance active power and reactive power in real time, however, the dynamic characteristic of the voltage control strategy is not improved.

What is V / F control in a microgrid?

On the other hand, when the microgrid is operating in islandingmode, i.e. STS is open, apart from current control, an outer voltage controlloop should be added to the control system of the master inverter to provide thevoltage and frequency support for the slave inverters, which is known as v / f control.
