Primary and secondary control structures for a DC microgrid are reviewed in this paper. Droop control and DC bus signaling control are used mainly as primary control methods. Instantaneous DC bus voltage contains necessary data for forming different operating levels.
It is imperative to properly control the DC bus voltage and manage power among the sources and loads in order to maintain the stability and reliability of DC microgrids. DC microgrids can be controlled by employing centralized, decentralized, distributed, multi-level, and hierarchical control systems to ensure safe and secure operation.
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.
This article critically reviews two main aspects of DC microgrids: voltage control and power management. The challenges and opportunities for voltage control and power management in DC microgrids are discussed.
Several factors are responsible for this, such as DC converters presenting negative damping performance, the interaction between the DC microgrid and the DC converters and the DC voltage control
A nonlinear distributed control strategy is developed for the DC MicroGrid, assuring the stability of the DC bus to guar-antee the proper operation of each component of the MicroGrid. The energy storage
