Project Description

7. How HVDC supports integration of Renewables
• Capable of long distance interconnections for remotely
located resources
• Low line losses for remotely located resources
• Best available technology for interconnection to weak
grid interconnection points
• Digital, fast control over the direction of flow –
for a grid increasingly used for shifting available
intermittent resources
• "Ride-through" capability
