Abstract
As an important part of the modern energy system, the DC microgrid has shown significant advantages in the fields of distributed generation, energy storage and load management in recent years. This study takes power electronics technology as the core, and deeply discusses its application and control strategy in DC microgrid, aiming to solve the problems such as low energy conversion efficiency and unstable power quality in the traditional AC power grid. By analyzing the topological structure and dynamic characteristics of power electronic converter, an optimization method based on hierarchical control architecture is proposed, which combines the advantages of master and slave control and droop control to realize the effective coordination of distributed power supply and load. At the same time, for the system stability problem, the adaptive damping controller is introduced, which significantly improves the anti-interference ability and dynamic response speed of the system.
