Efficient Convex optimization for Optimal PMU Placement in Large Distribution Grids [PDF]
2019 IEEE Milan PowerTech, 2019 The small amount of measurements in distribution grids makes their monitoring more difficult. Topological observability may not be possible, and thus, pseudo-measurements are needed to perform state estimation, which is required to control elements such as distributed generation or transformers at distribution grids.

Optimal PMUs placement considering ZIBs and single line and PMUs outages
AIMS Energy, 2020 Phasor measurement unit (PMU) is among the most important measurement devices in modern power systems. It measures the voltage and current phasors which have both magnitude and phase angle using a common timing reference. These measurements are utilized in real time applications of electrical power systems. The main drawback of PMUs is its high cost so
