A single‐ended protection method for flexible DC distribution grid
IET Generation, Transmission & Distribution, 2023 Considering that no current limiting inductances (CLIs) are installed at the end of the DC line in the flexible DC distribution grid, the protections relying on line boundary are no longer applicable. To overcome this problem, the paper proposes a single‐
