HVDC VSC (High Voltage Direct Current Voltage Source Conversion) technology is well-suited for integrating renewable energy resources due to its fast response time, ability to transmit power over long distances with low losses, provide reactive power support to weak grids, and allow power to flow in both directions. HVDC connections can help address intermittency of renewable resources by connecting geographically diverse projects, which have imperfect resource correlation and thus can help provide more reliable combined output. HVDC is also environmentally friendly as it uses direct buried cables that produce no audible noise, visual impacts or electromagnetic fields on land.

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
