An Investigation of Coordinated Attack on Load Frequency Control

IEEE Access, 2018
In this paper, optimal attack schemes against load frequency control (LFC) are studied by considering coordinated attack. By attacking sensor measurement (load) simultaneously, the attacker disrupts the normal operation of LFC, thus causing excess system

Emerging Effective Radiative Forcing in the Radiative Imbalance Since 2010

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Satellite observations indicate a substantial increase in Earth's top‐of‐atmosphere (the top of the atmosphere (TOA)) radiative imbalance since 2010. We estimate trends in effective radiative forcing (ERF) by separating TOA flux changes into forcing and response components, using feedback parameters derived from observed and simulated ...

Applying model predictive control to power system frequency control [PDF]

, 2013
Model predictive control (MPC) is investigated as a control method which may offer advantages in frequency control of power systems than the control methods applied today, especially in presence of increased renewable energy penetration. The MPC includes

A Novel 10‐Protein Score for Liver Fat Content Predicts Cardiovascular‐Kidney‐Metabolic Disease Risk

Advanced Science, Volume 13, Issue 10, 18 February 2026.
A novel 10‐protein plasma score precisely quantifies liver fat, outperforming the fatty liver index. It robustly predicts the risk of numerous cardiovascular‐kidney‐metabolic diseases and integrates with genetic data for precision prevention, offering a practical alternative to magnetic resonance imaging (MRI). Abstract Liver fat content (LFC) is a key

Data‐Driven Dual‐Channel Dynamic Event‐Triggered Load Frequency Control for Multiarea Power Systems Under DoS Attacks

Energy Science &Engineering, Volume 14, Issue 2, Page 780-792, February 2026.
ABSTRACT System dynamics uncertainties and cyberattacks pose significant challenges to load frequency control in power systems. This paper presents a data‐driven load frequency control strategy for interconnected multi‐area power systems subject to denial‐of‐service attacks that disrupt both feedforward and feedback communication channels.
