Malicious synchrophasor detection based on highly imbalanced historical operational data

open access: yesCSEE Journal of Power and Energy Systems, 2019
By maliciously manipulating the synchrophasors produced by phasor measurement units in power systems, cyber attackers can mislead the control center into taking wrong actions.

Random load fluctuations and collapse probability of a power system operating near codimension 1 saddle-node bifurcation [PDF]

open access: yes, 2012
For a power system operating in the vicinity of the power transfer limit of its transmission system, effect of stochastic fluctuations of power loads can become critical as a sufficiently strong such fluctuation may activate voltage instability and lead ...

Signal selection and latency compensation in wide area controlled power system

open access: yesEnergy Science &Engineering, Volume 13, Issue 8, Page 3885-3902, August 2025.
Abstract This paper presents a new approach for selecting signals for the monitoring and control of power systems over a wide area. The approach solves the twin problems of locating Phasor Measurement Units for observability and placing dynamic controllers for controllability using distinct techniques.

Cyber-Attacks in PMU-Based Power Network and Countermeasures

open access: yesIEEE Access, 2018
The notion of cyber-physical power grid is to use metering, communication, and control to make an intelligent and autonomous power system. Therefore, the smart meters form the basis of the cyber-physical system.

Estimation of Power System Inertia Using Nonlinear Koopman Modes

open access: yes, 2018
We report a new approach to estimating power system inertia directly from time-series data on power system dynamics. The approach is based on the so-called Koopman Mode Decomposition (KMD) of such dynamic data, which is a nonlinear generalization of ...

Static VAr Compensator Control Using Phasor Measurement Unit Feedback Signals for Voltage Stability Improvement in Power Systems

open access: yesEnergy Science &Engineering, Volume 13, Issue 7, Page 3569-3587, July 2025.
Static VAr Compensators can provide significant improvement in power system stability. Phasor Measurement Units are used in combination with SVCs for fast and reliable control of its operation. By combining the VAr control and Voltage Regulation control methods of the SVC, superior performance is obtained.

PMU’s Behavior with Flicker-Generating Voltage Fluctuations: An Experimental Analysis

open access: yesEnergies, 2019
Phasor measurement units (PMUs), which are the key components of a synchrophasor-based wide area monitoring system (WAMS), were historically conceived for transmission networks.

Resiliency assessment methodology for synchrophasor communication networks in a smart grid cyber–physical system

open access: yesEnergy Reports, 2022
The smart grid cyber–physical system (SGCPS) is the latest evolution of the traditional power system. Synchrophasor application in the SGCPS is responsible for wide area monitoring and control of the grid.
