Disadvantages of master-slave control in microgrids
A systematic review of robust control strategies in DC microgrids
From a system-level control point of view, master-slave and droop control are the two main strategies adopted to control the dc bus voltage. In master-slave control diagram,

6 FAQs about [Disadvantages of master-slave control in microgrids]
What are the disadvantages of dc microgrid?
The aforesaid disadvantages of AC microgrids such as control complexity and synchronization with utility grid is no longer prominent in DC microgrid. The advantages offered by DC microgrids are ease of installation, elimination of inverter and fuel costs. Power Quality issues are also not prevalent in DC Microgrids.
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 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.
What happens if a microgrid fails?
In case of any malfunction in the power grid other than the routine operation, the microgrid is separated from the power grid and switched to the isolated (off-grid) mode of operation, and thus, local loads can continue their operation ( Justo et al., 2013 ).
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.
Can a microgrid survive if a master unit fails?
The major shortcoming of this methodology, however, is that in case of failure of the master unit there is no chance for the microgrid to survive. However, if the maximum regulation capacity of the master unit is not sufficient to balance the system during the islanding transition, also this procedure can fail.
