System Frequency as Information Carrier in AC Power Systems

Improved disturbance detection and load shedding technique for low voltage islanded microgrids

“…In addition to this, most of the renewable sources are integrated into the power system through the power electronic inverters. The quick response of inverters results in high RoCoF immediately after disturbances in renewable‐based systems compared to conventional systems [10]. Thus an initial RoCoF, occurring just after the disturbance and before any control actions become active, is relatively high in renewable‐based systems compared to conventional systems [11].…”
