Monitor Placement for Reliable Estimation of Voltage Sags in Power Networks

A two-fold monitor placement method is developed to overcome the limitations of existing approaches for determining voltage sag monitoring programs; a generalization of an optimal monitor placement method for fault location that better suits the foreseen expansion in power system monitoring, and a simplified version of this that can be applied when resources are limited. The proposed method is tested in the IEEE-RTS and in a 295-bus generic distribution system (GDS) and compared with existing methods.
