Abstract

The recent proliferation of data is revolutionizing the practice of power system monitoring and control. With the Smart Grid initiative, more than two thousand multi-channel phasor measurement units (PMUs) [37] have now been installed in North America [35]. PMUs can directly measure GPS-synchronized bus voltage phasors, line current phasors, and the frequency, at a rate of 30 or 60 samples per second per channel. Compared to the conventional Supervisory Control and Data Acquisition (SCADA) systems that only provide measurements every 2–5 s, which are not accurately synchronized in time, PMUs can drastically improve the system visibility and enhance the situational awareness.
