6 FAQs about [Microgrid master-slave control principle]

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 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.

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.

What are microgrid control objectives?

The microgrid control objectives consist of: (a) independent active and reactive power control, (b) correction of voltage sag and system imbalances, and (c) fulfilling the grid's load dynamics requirements. In assuring proper operation, power systems require proper control strategies.

What are the studies run on microgrid?

The studies run on microgrid are classified in the two topics of feasibility and economic studies and control and optimization. The applications and types of microgrid are introduced first, and next, the objective of microgrid control is explained. Microgrid control is of the coordinated control and local control categories.
