Super grids?
European visions
- Hydro power and pump storage -Scandinavia
- +50 GW wind power in North Sea and Baltic Sea
- Hydro power & pump storage plants - Alps

What is HVDC?
AC-DC conversion ---- DC-AC conversion (remote location)
Long distance DC transmission lines: >50km submarine, >1000km overhead
AC-DC conversion ---- DC-AC conversion
DC tie
Different frequency or incompatible frequency control
Why HVDC?
- Transmission of large amount of power over long OH-lines
- For crossing long submarine distances
- HVDC enables transmission of more power with less Right of Way (ROW)
- Control over the power exchanges between two areas
- Flexibility of HVDC enables improvement of performance of the overall AC/DC system
- Investment cost

HVDC configurations
- Back to back
- Multi-terminal systems
- Point to point transmissions (Mono+Bipolar)
