The Rise of HVDC and Promise of Supergrids

摘要

High voltage direct current (HVDC) isn't new. Direct current transmission lines have been successfully transmitting electricity since the 1950s. In fact, records of experimental use of HVDC date back to the late 1800s - the time when Thomas Edison, George Westinghouse and NikolaTesla, as well as other innovators in North America and Europe were "debating" the use of alternating current (AC) vs. DC for electricity delivery.
