DC grid has been deemed as the enabling technology for future power systems. Within the dc grid, multi-terminal dc node (MTDN) serves as the key component for voltage/power conversion and fault protection. Configurations of MTDN are explored in this paper. The similarity of MTDN to a classical ac substation is first identified, and three series of “dc substation” have been developed on the basis o...
