6 FAQs about [Microgrid master-slave operation 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 is the nature of microgrid?

The nature of microgrid is random and intermittent compared to regular grid. Different microgrid structures with their comparative analyses are illustrated here. Different control schemes, basic control schemes like the centralized, decentralized, and distributed control, and multilevel control schemes like the hierarchal control are discussed.

What is master-slave control mode?

Master-slave control mode is a typical example of a centralized control scheme. A master-slave coordinated control mode is proposed in Reference 225 to regulate the DC bus voltage, where, ESS units are considered as the master and the remaining units like the renewable energy source and loads are considered as the slaves to regulate their power.

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.

How many control modes are there in a microgrid?

These modes consist of: master-slave, 222 peer-to-peer 223 and combined modes. 224 For a small microgrid, usually, the master-slave control mode is applied. In the sequence of master-slave control mode: the islanding detects, the microgrid load change, and the grid lack for power.
