False Data Injection Attacks on Phasor Measurements That Bypass Low-rank Decomposition

, 2017
This paper studies the vulnerability of phasor measurement units (PMUs) to false data injection (FDI) attacks. Prior work demonstrated that unobservable FDI attacks that can bypass traditional bad data detectors based on measurement residuals can be ...

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.

Optimal PMU Placement via Quantum Optimization

IEEE Transactions on Smart Grid
Phasor Measurement Units (PMUs) are essential for real-time monitoring and improving grid observability. Determining the optimal PMU installation is critical, especially as the penetration of renewable energy resources increases, as the Optimal PMU Placement (OPMUP) can guarantee full system observability and reduce the installation cost.
