What are the advantages of a microgrid?

Among the advantages of the proposed control, we can mention operation at a constant frequency, high robustness, ability to respond to load against strong damping, improved power, and current control, and easy connection. In rural areas, in Li and Ho (2020), a microgrid is presented, which works based on the DC module PNP.

What are the control strategies of a microgrid?

Then, the overall control strategy of the microgrid is classified. The research status of the four control strategies, namely peer control, master-slave control, hierarchical control and decentralized control is described respectively. Finally, the advantages and disadvantages of various control strategies of the microgrid are elaborated.

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.

Are microgrids reliable?

Microgrids (MGs) which have AC, DC, and DC/AC types, have received much attention due to their many advantages. MGs can be a suitable solution for supplying power to remote and sensitive areas and they can also increase the reliability of the system. Like all systems, MGs need a reliable control system to provide proper operation.

How can a microgrid improve the performance of SMG?

Looking at the rise in population and power demand, the AC, DC, and hybrid microgrid applications are gaining interest. Many researchers suggested different robust control techniques, storage devices, and inverter topologies to improve the performance of SMG by providing better stability, voltage, and frequency control.
