HVDC converter stations valves are operated by a computerized control system, which enables transmitted power to be precisely controlled, a feature unique to HVDC systems. In AC transmissions, the power cannot be directly controlled, but depends on external factors. An HVDC Light converter station is much smaller than a converter station for HVDC Classic.

High-voltage direct current - Wikipedia high-voltage, direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems..
