Optimal PMU Placement via Quantum Optimization
IEEE Transactions on Smart GridPhasor 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.

Optimal Multistage PMU Placement for Wide-Area Monitoring
IEEE Transactions on Power Systems, 2013 This paper proposes a novel optimization model to maximize the power system observability by placing phasor measurement units (PMUs) in a multistage manner. The problem is constrained by the financial budgets available at each installation stage. The budget may be spent on purchasing and installing new PMUs and relocating PMUs already installed in the ...

Optimal co-placement method considering non-homogeneous PMU channel capacities
IET Smart Grid, 2020 In this study, a topology defragmentation method is developed for co-placements of phasor measurement units (PMUs) and their communication infrastructure. Electric power networks are defragmented into sets of branches and a realistic cost model, based on

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.

Advanced Materials, EarlyView.Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a
