High-Gain Disturbance Observer-Based Robust Load Frequency Control of Power Systems with Multiple Areas

, 2017
This paper proposes a high-gain disturbance observer (HDOB)-based controller for load frequency control (LFC) of power systems with multiple areas. The main goal of LFC problem is to maintain the frequency to its nominal value.

Persistent magnetic resonance imaging‐derived static anterior tibial translation after anterior cruciate ligament reconstruction is associated with elevated cartilage T2 relaxation times but not serum biomarkers

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Persistent, static anterior tibial translation (sATT) alterations following anterior cruciate ligament reconstruction (ACLR) may influence cartilage health. T2 relaxation times and serum biomarkers of cartilage degradation/bone resorption provide insight into osteoarthritis development.

Improving the MPC Performance of the Model in Order to Improve the Frequency Stability of the Two-Area Microgrid [PDF]

International Journal of Industrial Electronics, Control and Optimization
: In the context of frequency stability in a two-area microgrid, it is crucial to address the fluctuations in frequency caused by load disturbances. To achieve this, an effective load-frequency control (LFC) system, which serves as the secondary control,

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

Impact of a High‐Fiber, Fruitless Diet on the Gut Microbiome, and Health of Captive Orangutans

Zoo Biology, EarlyView.
Transitioning captive orangutans to a high‐fiber, fruitless diet improved gut microbiome diversity, enhanced gastrointestinal health, and reduced stress‐related behaviors. This study demonstrates the significant benefits of tailored dietary interventions in promoting the health and welfare of zoo‐housed primates.
