To better cope with power fluctuations in DC microgrids and meet the energy balance requirements of electrical signal resources

research is conducted on power and energy management strategies for mechanical transformers based on hybrid energy storage in DC microgrids. Analyze the application of mechanical transformers in DC microgrids

and achieve complementary functions for hybrid energy storage systems

completing the positioning of microgrid system architecture and functions. On this basis

a hierarchical control architecture is proposed

and key control algorithms are combined to improve power and energy management strategies. Using the dynamic response limitation of mechanical transformers as a starting point

manage the lifespan of hybrid energy storage

and analyze the challenges and specific solutions faced by hybrid energy storage technology.
