Abstract
In order to suppress the busbar voltage fluctuations in the DC microgrid, this paper establishes an optical storage DC microgrid system with a hybrid energy storage system to achieve the purpose of stabilizing the DC bus voltage. This system focuses on the component hybrid energy storage unit, and uses the structure of three batteries and supercapacitors (SC) in parallel to improve the stability of the system, while ensuring the frequency division distribution between devices.
