Equal‐area criterion and analytical model for transient stability assessment of hybrid AC–DC transmission system using voltage sourced converter

open access: yesIET Renewable Power Generation, 2023
An analytical model for transient stability assessment of hybrid AC–DC transmission systems is formulated, implemented, and validated. The equal‐area criterion, as known from the transient stability analysis of AC power systems, is redeveloped for AC–DC ...

A Comparison of the Predictive Validity of Self-Esteem Level and Directly Measured Self-Esteem Stability in the Temporal Prediction of Psychological Distress

open access: yesFrontiers in Psychology, 2020
In contrast to the widely used assessment approach in which self-esteem stability is measured as the standard deviation of repeated measurements, direct measurements of self-esteem stability have hardly ever been implemented in longitudinal studies.
