The World of HVDC

Classic HVDC . Its been around for 50 years

OTHER HVDC CCC = 2400 MW RCC = 0 MW VSC = 943 MW

USA T = 7720 MW

C = 0 MW B = 1900 MW

Canada T = 6000 MW C = 312 MW B = 1820 MW

Europe T = 0 MW C = 8155 MW B = 1750 MW

India T = 5600 MW C = 0 MW B = 3000 MW

China T = 16250 MW C = 0 MW B = 0 MW

Asia T = 2100 MW C = 2150 MW B = 1800 MW

Australasia T = 0 MW C = 2160 MW B = 0 MW

Africa T = 2480 MW C = 0 MW B = 0 MW

Middle EastGulf States Interconnection Project

Combining HVDC and AC


10/22



Main driver for the projectwas demand growthexpectations in the region:

2003: 32GW

2010: 49GW

2028: 94GW

Studies showed that interconnectionwould have many benefits:

Reduced capacity needed in each systemsince it would allow the sharing of energysupply

Allow sharing of spinning reserves

Allow exchange of energy, leading to loweroperating costs

Increase overall system reliability,especially under emergencies

Could ultimately lead to energy market
