Research on Circuit Breakers in DC Microgrids
This paper investigates circuit breakers in DC microgrids, introducing fundamental DC microgrid concepts and refining basic module designs. It proposes a practical architecture for household smart DC microgrids, references European microgrid standards, and optimizes voltage levels through literature comparison to establish appropriate voltage specifications. The study presents a DC Bus Voltage Signal (DBS)-based control strategy incorporating converter control for renewable energy sources and energy storage devices. For load-DC bus interaction, a novel intelligent DC circuit breaker topology utilizing soft-switching technology is proposed and validated through simulation. This breaker achieves zero-current mechanical switching interruption and serves as a fundamental module for power routers, enabling energy routing concepts while providing new perspectives for DC microgrid development.
