I agree with Manya and adding that:-
1-HVDC transimission line have lower losses than Ac lines
for the same power capacity.
2-It is very easy to control the active power in the link
in HVDC systems.
3-HVDC system is the only way to make an exchange of power
between two different networks.
HVDC . . . High Voltage DC system
