HVDC Grids – Why? Regional to continental HVDC Grids
Why DC Grids vs point to point DC links or AC?
Only relevant offshore solution
More efficient on long distances
Fewer converters – lower cost
Redundancy
Why now:
Offshore wind, remote solar, grid constraints
HVDC Light systems and components mature
Right of Way
Challenges:
DC Breakers & DC/DC Converters

Asian power grid example by ABB
DC grid for the solution:
• DC grid is the best solution for the
vision
• Different requirement should have
different technologies:
• Latest technology (VSC) connects the
weak AC network and light load area.
• Classic technology (LCC) connects the
high power requirement and heavy load
area.
• So called DC grid.

High Voltage DC Transmission (HVDC) Motivations and Benefits of HVDC
Higher Transmission Capacity than HVAC
Lower losses than AC on Long Distances
Possibility to use Cables (Land or Sea)

Enabling the next generation grid
The DC hybrid breaker enables the next generation of the grid, coping with new
challenges like large scale renewable power transmission
DC grids can provide power transmission in a highly efficient and stable way,
DC transmission can be up to 50% more efficient than AC transmission
Large scale integration and transmission of renewable power in EU and US.
Potentially for countries that tap hydropower over long distances (China, India)
Critical technology for European grid and Desertec grid visions
Interesting business opportunity for ABB in mid- to long term
