What are DC microgrids?

Policies and ethics DC microgrids are a promising solution for integrating distributed generation into the main grid. These microgrids comprise distributed generation units, energy storage systems, loads, and control units. They can operate in grid-connected and off-grid modes (islanded...

Are DC microgrids planning operation and control?

A detailed review of the planning, operation, and control of DC microgrids is missing in the existing literature. Thus, this article documents developments in the planning, operation, and control of DC microgrids covered in research in the past 15 years. DC microgrid planning, operation, and control challenges and opportunities are discussed.

What are microgrid control strategies?

Microgrid control strategies, which have a very important effect on the performance of the microgrid system and make the microgrid more stable and reliable, are explained in detail. Emerging communication technologies for DC microgrids are explained, and machine learning techniques in DC microgrids are discussed in light of new developments.

How to ensure the safe operation of DC microgrids?

In order to ensure the secure and safe operation of DC microgrids, different control techniques, such as centralized, decentralized, distributed, multilevel, and hierarchical control, are presented. The optimal planning of DC microgrids has an impact on operation and control algorithms; thus, coordination among them is required.

How to improve the efficiency of dc microgrid?

Finally, efficiency of the DC microgrid should be improved, that is, the future trends in hierarchical control for DC microgrid would be related to energy management systems (EMSs), giving references to the tertiary control in order to optimize the efficiency of the system.

Can distributed energy storage be used in a dc microgrid?

Due to the current development limitations, the user-side distributed energy storage configuration mode in the DC microgrid is extensive, and the types of energy storage are relatively simple. The potential application value of energy storage needs to be explored urgently.
