Large-amplitude vibration analysis of a strong nonlinear tapered beam using continuous piecewise linearization method

open access: yesJournal of King Saud University: Engineering Sciences, 2022
The large-amplitude free vibrations of an inextensible tapered beam with inertia and static nonlinearities were investigated using the continuous piecewise linearization method (CPLM).

Distributed Machine Learning Approach to Fast Frequency Response-based Inertia Estimation in Low Inertia Grids [PDF]

open access: yes, 2020
Recent updates to the IEEE 1547-2018 standard allow active participation of distributed energy resources (DERs) in power grid services with the goal of increased grid reliability and resiliency.

Meeting frequency response requirements with uncertain system inertia — A UK perspective [PDF]

open access: yes, 2016
National Grid has a statutory obligation to manage the frequency between pre-defined limits. If there isn't effective frequency response available then the likelihood of a frequency excursion outside of statutory limits will increase.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Co-Optimization of Inertia and Droop Control Coefficient for Grid-Forming Photovoltaic-Storage System Considering Capacity Limits

open access: yesZhongguo dianli
As the renewable energy's share in the power system continues to increase, the inertia level of the system gradually decreases. The effective approach to tackle frequency stability issues is to configure energy storage to enable photovoltaic (PV) power ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Optimal Configuration of Virtual Inertia and Fast Frequency Response in Low-Inertia Power Systems

open access: yesEnergies
To address the declining system inertia levels and the associated frequency security challenges arising from the increasing penetration of renewable generation, this study proposes a coordinated configuration of virtual inertia (VI) and fast frequency response (FFR) resources in low-inertia power systems.

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Importance of linking inertia and frequency response procurement: the Great Britain case [PDF]

open access: yes, 2021
In order to decarbonise the electricity sector, the future Great Britain (GB) power system will be largely dominated by non-synchronous renewables.
