Advanced Transmission Technologies

ATTs are a solution set for transmission planners, composed of grid-enhancing technologies (GETs) and advanced conductors, which help address the issue of growing load and slow interconnection of new generation resources. We present structured methodologies for incorporating ATTs into the planning domains of:

• Transmission planning in RTO/ISO regions
• Interconnection studies for new generation
• Integrated resource planning (IRP) and procurement in regulated utilities.

The ATTs addressed are dynamic line ratings (DLR), advanced power flow control (APFC), topology optimization (TO), and advanced conductors. Each ATT is assessed in depth, including operational considerations and practical use case studies.
