Ultra-Efficient Intelligent MVDC Hybrid Circuit Breaker
The proposed breaker is installed close to loads to rapidly detect and react to the short-circuit fault. Thus, it could enable an increased number of electronic loads that operate using DC, such as ultra-fast electric vehicle charging stations and utility scale energy storage battery units, to connect to the MV distribution grid. This would improve overall power delivery efficiency.
Proliferation of MVDC systems protected by more effective DC circuit breakers could drive higher energy efficiency, lower equipment costs, and bolster grid resiliency.
