The concept of a phasor synchronized with the power system was introduced in the 1980s and standardized for the first time with the standard IEEE 1344. That measurement concept was further developed in the current synchrophasor standard, IEEE C37.118 that was completed in 2005. It is currently undergoing revision to fully define the measurement in all conditions including dynamic changes in the...

Phasor Measurement Units (PMU) are playing an increasingly important role in wide-area monitoring and control of power systems. PMUs allow synchronous real-time measurements of voltage, phase angle and frequency from multiple remote locations in the grid, enabled by their ability to align to Global Position System (GPS) clocks. Given that this ability is vulnerable to GPS spoofing attacks, whic...

A two-stage machine learning-based approach for creating synthetic phasor measurement unit (PMU) data is proposed in this article. This leverages generative adversarial networks (GAN) generation and incorporates neural ordinary differential equation (Neural ODE) to guarantee underlying physical meaning. We utilize synthetically create massive eventful PMU data, which would otherwise be difficul...

Smart grids are the latest technology to generate and dispatch an optimal amount of power. Thus, there is a need for stability analysis in smart grid systems. If incorporated into power system, then phasor measurement unit (PMU) used measure voltage, current, frequency. Additionally, central control monitors controls However, possibility inserting wrong data as PMUs transmitting through Interne...

This paper presents a fast model-agnosticmethod for recovering noisy Phasor Measurement Unit (PMU) data streams with missing entries. The measurements are first transformed into Page matrix, and the original signals reconstructed using low-rank matrix estimation based on optimal singular value thresholding. Two variations of recovery algorithm shown- a) an offline block-processing method imputi...

This study treats the optimised one-port (reflection coefficient) and two-port (shunt-through/series-through) measurement methods for complex permeability determination of solid soft magnetic materials using a vector network analyzer (VNA) at frequencies from 9 kHz to 6.5 GHz. The principle of measurement methods, the relationships of measured phasor voltage ratio (Sparameter) to complex impeda...

In this paper, the load response-based equivalent model is proposed to develop a more sturdy method for transmission capability estimation of power grid. Based on real-time phasor measurement unit (PMU) measurements, grid modelled as multi-port based coupled single-port models. The associated critical branch in identified and modified by shaping factor construct model. According modification, d...
