| Abstract: |
| In DC microgrids, hybrid energy storage systems are used to improve the performance of renewable energy power generation systems and maintain the overall power balance within the grid. Reasonable control strategies are the key for giving full play to the characteristics of different energy storage devices and ensure the safe and stable operation of the system. This paper reviews the latest developments in the control strategy of hybrid energy storage system DC microgrids and summarizes the research from three aspects: basic control ideas, dynamic response capability improvement methods, and control strategies considering the state of charge, and visually demonstrates advantages and disadvantages in the form of a table. Aiming at the limitations of the existing control strategies, combined with technological progress in related fields, the future development direction is prospected.
