About this document
Active Frequency Drift for Islanding Prevention by Marcos Rosa dos Santos is a document available to read on EtoBox.
1) The active frequency drift (AFD) method forces the frequency of an islanded microgrid to drift up or down to detect islanding situations. 2) AFD works by slightly distorting the current injected by PV systems, which causes the frequency to drift until detected by protection devices. 3) While AFD is effective for resistive loads, its effectiveness for nearly resonant loads with unity displacement power factor is unknown and requires further study.
