Synchrophasors-based methodologies for enhancing the flexibility of congested grids

Modern power systems undergo unprecedented changes, especially due to the replacement of large conventional power plants with dispersed and distributed renewable power generators connected to both transmission and distribution grids, which is causing several concerns on existing transmission and distribution networks, which are often operated very close to their maximum allowable operational limits, especially in the presence of grid congestions. To address this problem, power system operators perform preventive solutions by building new transmission and distribution assets, to increase grid meshing and inter-area power transfer capacity. Although these actions may enhance the load capability of the transmission assets and the grid flexibility, building new infrastructures is not a trivial task due to the related economic, social, and environmental matters. This panel will present the latest experience from manufacturing, specialists, academia, and Industry on the enabling synchrophasor-based technologies for increasing the flexibility, efficiency, reliability and security of transmission and distribution systems. Special attention is given to the large-scale deployment of these technologies on existing transmission and distribution assets to allow system operators to enhance the grid flexibility in the presence of severe grid congestions.
