Integration of renewable generation sets high requirements for real-time situational awareness of power systems. FNET/GridEye, a synchrophasor measurement network for wide-area power system monitoring has been assisting realtime situational awareness and helping improve reliability in many power grids for 14 years. To aid operators confronting challenges from growing renewables, FNET/GridEye continues increasing its measurement accuracy and enhancing its functionalities. This paper provides an overview on the mostrecent FNET/GridEye application improvements that help power grid operation with high renewable penetration. The real-time applications presented in this paper include event location, oscillation monitoring, inertia estimation, and islanding detection.
