Power-Supply Systems Reliability Control [PDF]
EAI Endorsed Transactions on Energy Web, 2018 System reliability control is proposed to maintain through the usage of the operating time between the system components' failure. Usually, trouble-free (reliability) is assessed considering component failures. Almost all the system probabilistic parameters were determined via the component failures.

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installed at the end of the DC line in the flexible DC distribution grid, the protections relying on line boundary are no longer applicable.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‐
