Improved Load Frequency Control Using a Fast Acting Active Disturbance Rejection Controller

, 2017
System frequency may change from defined values while transmitting power from one area to another in an interconnected power system due to various reasons such as load changes and faults.

On robust load-frequency regulation in a restructured power system [PDF]

, 2003
An approach based on structure singular value theory is proposed for the design of robust load frequency controller in response to the new technical control demand for large scale power systems in a deregulated environment.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Photovoltaic (PV) Contribution to the Primary Frequency Control

Solar Energy and Sustainable Development, 2012
Photovoltaic (PV) technology is among the most efficient and cost effective renewable energy kinds currently available on the market. The connection of a large number of PVs to the grid may influence the frequency and voltage stability of the power system.

HDE-CGWO-Based Optimal Load Frequency Control for Nonlinear Power Systems

Energies
In modern power-system load frequency control (LFC), proportional–integral–derivative (PID) controllers are widely used because of their simple structure and ease of implementation.

Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Robust load-frequency control design for time-delay power systems [PDF]

, 2005
This paper addresses a control strategy to design a PIbased load-frequency control (LFC) in face of communication delays. First the PI-based LFC design is transferred to a static output feedback (SOF) control design and then to obtain the optimal PI ...

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.
