Optimal PMU Placement in the Presence of Conventional Measurements

International Transactions on Electrical Energy Systems, 2022
This article presents a novel method for optimal phasor measurement unit placement (OPP) for full power system observability in the presence of conventional measurements. The method considers eligible PMU placements that may be omitted by existing OPP methods and hence may provide a better solution and can guarantee that the PMU placement can restore ...

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.

Multi Objective for PMU Placement in Compressed Distribution Network Considering Cost and Accuracy of State Estimation

Applied Sciences, 2019
A phasor measurement unit (PMU) can provide phasor measurements to the distribution network to improve observability. Based on pre-configuration and existing measurements, a network compression method is proposed to reduce PMU candidate locations. Taking

Volatile ZrO2 Antiferroelectric Tunnel Junctions for Rapid, Energy‐Efficient Physical Reservoir Computing

Advanced Science, EarlyView.
An antiferroelectric tunnel junction serves as a reservoir computing node, where field‐induced phase transitions and spontaneous ZrO2 relaxation deliver nonlinear fading memory. An In‐Ga‐Zn oxide interlayer enlarges the memory margin and multibit state richness.
