The PMU data is increasingly used in the grid monitoring system SCADA. As the DFT algorithm used in PMUs fails to distinguish the fundamental frequency signal with low-frequency interference, the low-frequency disturbance (LFD) included in fundamental frequency variable data, which are collected from PMUs, will affect the correctness of calculation and analysis of the power system's steady state....
Synchronized phasor measurements can reveal important insights about the health and stability of the power grid in near-real time. Unfortunately, the high cost associated with the installation of phasor measurement units (PMUs) has limited their adoption in the electric utility industry. The Frequency Monitoring Network (FNET) was created to provide low-cost, high-accuracy frequency and voltage phase...
