A probabilistic scenario-based optimal day-ahead economic operation was presented for a hybrid AC/DC microgrid system. The cited articles related to the EMS of a DC microgrid for residential applications in this
An overview was presented of DC microgrid applications, economic operation and control, microgrid configuration comparison, and global state-of-the-art DC microgrid projects, as well as a discussion of emerging trends in DC microgrid
The AC/DC hybrid microgrid has a large-scale and complex control process. It is of great significance and value to design a reasonable power coordination control strategy to maintain the power balance of the system. Based on hierarchical
Direct-current (DC) microgrids have gained worldwide attention in recent decades due to their high system efficiency and simple control. In a self-sufficient energy system, voltage control is an important key to dealing with
One of the applications of DC microgrids that have already been implicated is associated with data centers, but there are many other applications where DC microgrids can be an important asset. One application area in
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.
DC microgrid architecture with their application, advantage and disadvantage are discussed. The DC microgrid topology is classified into six categories: Radial bus topology, Multi bus topology, Multi terminal bus topology, Ladder bus topology, Ring bus topology and Zonal type bus topology.
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.
Power-sharing and energy management operation, control, and planning issues are summarized for both grid-connected and islanded DC microgrids. Also, key research areas in DC microgrid planning, operation, and control are identified to adopt cutting-edge technologies.
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.
This review paper is inspired by the recent increase in the deployment of DC microgrid systems for real-world residential and industrial application. Consequently, the paper provides a current review of the literature on DC microgrid topologies, power flow analysis, control, protection, challenges, and future recommendation.
