The AES Corporation and LineVision have published a case study related to the ongoing demonstration project from the largest single deployment of Dynamic Line Ratings (DLR) in the United States.
In the case study, the companies said standard transmission lines with extra high voltage and steel structures are “well-suited” for DLR models. The DLR deployment “significantly improved” situational awareness, the companies said. However, some high-voltage and sub-transmission lines, especially those with older construction and wood pole support, may require additional model training.
This deployment, announced last year, included 42 LUX non-contact sensors and forms part of a joint project to assess how grid-enhancing technologies could increase the transmission capacity on the existing power grid.
As part of the joint project, LineVision installed its patented non-contact sensors on transmission structures owned by AES’ utilities in Indiana and Ohio. The companies said early learnings from the project underscore the potential for DLR to improve real-time monitoring.
DLRs are calculated using real-time field measurements and conductor position to determine the maximum carrying capacity of the transmission line, enabling it to be continuously optimized and to support the integration of growing renewables capacity to the grid.
“Our collaboration with AES marks a significant milestone in advancing grid modernization efforts across the United States,” said Hudson Gilmer, CEO of LineVision. “By deploying DLR technology, we are empowering utilities like AES to maximize the efficiency and reliability of their grid infrastructure while minimizing costs and environmental impact.”
Moving forward, LineVision and AES will share further insights from the deployment project to encourage the acceleration of DLR adoption throughout the U.S.
“As stewards of energy, we are committed to exploring technologies that enhance the efficiency of the grid and ensure safe and reliable power for our customers,” added Alexina Jackson, VP of Strategic Development, AES. “The deployment of LineVision’s DLR technology on our grid also provides valuable insights for planning and operations of the increasingly digital grid.”
