Low-Voltage Ride-Through Operation of Grid-Connected Microgrid Using Consensus-Based Distributed Control

open access: yesEnergies, 2018
Since the penetration of distributed energy resources (DERs) and energy storage systems (ESSs) into the microgrid (MG) system has increased significantly, the sudden disconnection of DERs and ESSs might affect the stability and reliability of the whole ...

Patellar Tendon Imbrication With a Double‐Row Configuration for the Treatment of Patella Alta in Skeletally Immature Patients

open access: yesArthroscopy Techniques, EarlyView.
Abstract Patella alta is a major anatomical risk factor for patellar instability. Although a tibial tubercle osteotomy with distalization has been described in this context, a patellar tendon imbrication more directly addresses the pathoanatomy and avoids the risk of physeal and apophyseal injury in skeletally immature patients.

Biographies, ontological security and the socio‐spatial politics shaping teachers' mobility in remote Australia

open access: yesBritish Educational Research Journal, EarlyView.
Abstract The global teacher shortage continues to intensify, with disparate impacts across geographic and socio‐economic communities. In Queensland, Australia, where this study originates, post‐COVID teacher shortages have intensified workforce pressures, leaving several regional, rural and remote schools as some of the ‘hardest‐to‐staff’ in the ...

Low-Voltage Ride-Through Algorithm for Grid-Forming Converters

open access: yesIEEE Transactions on Power Electronics
In recent years, the increasing integration of renewable energy sources into power systems has led to significant changes in grid operation. Power electronic converters are primarily used to connect these power plants to the electrical system and, as key components in modern power systems, grid-forming (GFM) converters have emerged to provide the ...

Powerful transformations: The experiences of higher education teaching staff who were first‐generation university students

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Historically, a university education has been seen primarily as a route for the middle classes to achieve professional qualifications while structural barriers have served to restrict entry to individuals from particular demographics. First‐generation students (FGS), often with low socio‐economic backgrounds, face multiple barriers to Higher ...
