Optimal Placement of Phasor Measurement Unit in Smart Grids Considering Multiple Constraints

Journal of Modern Power Systems and Clean Energy, 2023
The distribution of measurement noise is usually assumed to be Gaussian in the optimal phasor measurement unit (PMU) placement (OPP) problem. However, this is not always accurate in practice.

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.
