EIA study examines the role of high-voltage power lines in integrating renewables

A new study commissioned by EIA examines the role of high-voltage direct current (HVDC) lines in integrating renewables resources into the electric grid. The review indicates that, although applications in the current electric transmission network are limited, HVDC lines have a number of potential benefits including cost effectiveness, lower electricity losses, and the ability to handle overloads and prevent cascading failures. These attributes mean that HVDC lines could, if properly configured, help mitigate some operational issues associated with renewable generation. More »
