Review of HVDC systems for enhancing resilience after extreme natural events
Compared with AC systems, HVDC systems are more flexible and potentially contribute to enhancing system resilience. Currently, three types of HVDC technologies, LCC‐HVDC (Line‐commutated Current‐sourced Converters, LCC), VSC‐HVDC (Voltage Sourced ...

A New DC-DC Converter Linking LCC-HVDC Transmission Networks [PDF]
Transferring bulk power via high voltage direct current (HVDC) transmission is dominated by line commutated converters (LCC). This is due to the robustness and higher ratings of the thyristors as well as the higher converter efficiency. Nevertheless, most of these transmission networks are point to point. This is due to the challenges of allowing multi-
