Susceptibility of Large Wind Power Plants to Voltage Disturbances — Recommendations to Stakeholders

Journal of Modern Power Systems and Clean Energy, 2022
Sufficient fault ride-through (FRT) of large wind power plants (WPPs) is essential for the operation security of transmission system. The majority of studies on FRT do not include all disturbances originating in the transmission system or the ...

Clinical Outcome Assessments in Parkinson's Disease: A Scoping Review of Current Rating Scales and Future Needs

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Clinical outcome assessments (COAs) are essential for evaluating symptom severity, treatment response, and disease progression in Parkinson's disease (PD). As clinical knowledge evolves, it is necessary to revisit the recommendation status on the COAs to ensure their continued relevance and validity. Objectives To provide an updated

Examination of fast frequency response capacity requirements considering frequency ride-through capabilities in distributed generators with legacy inverters

Energy Reports, 2023
Given the rapid increase in inverter-based distributed generators (IBDGs), their response and subsequent impacts on power system stability during abnormal power system conditions are becoming important. Recent events have shown that an unexpected loss of

Parallel Metric Tree Embedding based on an Algebraic View on Moore-Bellman-Ford

, 2015
A \emph{metric tree embedding} of expected \emph{stretch~$\alpha \geq 1$} maps a weighted $n$-node graph $G = (V, E, \omega)$ to a weighted tree $T = (V_T, E_T, \omega_T)$ with $V \subseteq V_T$ such that, for all $v,w \in V$, $\operatorname{dist}(v, w ...

Calculating the Interconnection Limit from a Comprehensive Voltage Evaluation for Distribution Systems with Large Distributed Energy Resources

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Japan is pursuing power source decarbonization and is thus reducing fuel‐based thermal power generation while promoting renewable energy resource use. Given the expected power fluctuations, this transition will require novel voltage management and control methods.

Retail investors' financial risk tolerance and their risk-taking behaviour: The role of demographics as differentiating and classifying factors

IIMB Management Review, 2015
This paper empirically examines whether demographic factors namely gender, age, marital status, income, occupation, and education could be used individually or in combination to differentiate among retail investors in terms of financial risk tolerance ...

Th1 cells are dispensable for primary clearance of Chlamydia from the female reproductive tract of mice.

PLoS Pathogens, 2022
Protective immune responses to Chlamydia infection within the female reproductive tract (FRT) are incompletely understood. MHC class II-restricted CD4 Th1 responses are believed to be vital for bacterial clearance due to their capacity to secrete IFN-γ ...

The economic foundations of powersharing: Evidence from Africa

American Journal of Political Science, EarlyView.
Abstract How—and with whom—do rulers share power? Existing research focuses on the strategic logic of powersharing. In this paper, we analyze its economic foundations. Powersharing is modeled as a subnational fiscal contract, in which rulers allocate political representation based on constituencies’ revenue potential. Empirically, we combine historical

Fast analytical calculation-based modeling method and fault ride-through parameters selection to enhance short-term voltage stability of grids with large-scale photovoltaic power plants

International Journal of Electrical Power & Energy Systems
Large-scale centralized photovoltaic power plants (PVPPs) connected to a power grid may cause short-term voltage instabilities during fault ride-through (FRT) processes.

Relationship between Biopsychosocial Factors and Financial Risk Tolerance: An Empirical Study

Vikalpa, 2016
Executive Summary Financial risk tolerance (FRT) refers to the retail investors’ willingness to accept the negative changes in the value of investment or an outcome that is adversely different from the expected one.
