6 FAQs about [Hierarchical coordination of DC microgrids]

What is a hierarchical control structure of a dc microgrid?

Thus, a hierarchical control structure was proposed to optimize the control of the DC microgrid , which is used for coordinating with multiple control objectives or optimal operation of the DC microgrid in various time-scales. Many scholars have made great efforts on the hierarchical control structure of the DC microgrid.

Do DC microgrids need coordination?

The optimal planning of DC microgrids has an impact on operation and control algorithms; thus, coordination among them is required. A detailed review of the planning, operation, and control of DC microgrids is missing in the existing literature.

What is dc microgrid?

DC microgrid is an efficient, scalable and reliable solution for electrification in remote areas and needs a reliable control scheme such as hierarchical control. The hierarchical control strategy is divided into three layers namely primary, secondary and tertiary based on their functionality.

What is the tertiary control structure in a community microgrid?

Aiming at a community microgrid with multiple AC and DC sub-microgrids, the hierarchical control structure is proposed to achieve the economic and coordinative control.especially, the tertiary control is implement to ensure the optimal coordination of an islanded community microgrid .

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.

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.
