HVDC Light, six key applications ABB-Toll Inauguration -13-
Improved grid reliability by HVDC Light, values Increased grid reliability by Fast and accurate voltage control Can not be overloaded Black start capability Short time to market by simplified permitting procedure ABB-Toll Inauguration -14 - DC lines will never be subject to an unforeseen increase of power flow due to the outage of system components. Therefore it is not necessary to reserve capacity margins on DC lines in order to fulfil the (n-1) principle. DC links can rather be operated at their rated power, unless there are limitations inside the adjacent AC networks. Source: IAEW/Consentec report 2001
