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.

The Impact of Tenapanor on Body Composition and Blood Pressure in Peritoneal Dialysis Patients: A Pilot Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Instruction Tenapanor potentially affects fluid volume and blood pressure. This study explored its effects on these parameters in patients undergoing peritoneal dialysis (PD). Methods We conducted a single‐arm, prospective observational study that enrolled 10 patients on PD with hyperphosphatemia who were newly initiated on tenapanor.

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.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

A scenario on load-frequency controller design in a deregulated power system [PDF]

, 2003
An approach based on mu-synthesis and analysis theory is proposed for the design of load frequency controller in response to the new technical control demand for power system in a deregulated environment.

Analysis of the Impacts of the Interaction Between Frequency-Dependent Loads and Virtual Inertia Control in an Isolated Microgrid

IEEE Access
Inverter-dominated microgrids are highly sensitive to disturbances owing to their low inertia. The accepted solution is to provide virtual inertia for frequency support.

Enhanced load frequency control: incorporating locational information for temporal enhancement

IET Generation, Transmission & Distribution, 2019
With the increasing penetration of renewables in power systems, frequency regulation is proving to be a major challenge for system operators using slower conventional generation, and alternative means to provide faster regulation are being actively ...
