Strategic retirement enhances electric vehicle battery circularity

This study demonstrates that strategically retiring electric vehicle batteries 1–2 years earlier can transform 40–50% of currently unreusable units into valuable second-life energy storage resources, significantly enhancing circularity and environmental sustainability through a proposed dynamic trade-in framework.

Feasibility of Mobile Point-to-Point Speed Enforcement: Real-World Evidence from Urban and Rural Queensland

This study demonstrates that mobile point-to-point speed enforcement is operationally feasible in Queensland, revealing that vehicle re-identification rates are primarily constrained by the number of road exits rather than camera separation distance, while also highlighting significant discrepancies between spot and average speed measurements.

Wide Area Protection of AC Networks Incorporating IBR Connected by HVDC Line

This paper proposes a wide area protection method for AC networks with HVDC-connected inverter-based resources that utilizes PMU data to identify suspected buses and employs superimposed current polarity analysis at line terminals to accurately detect and locate faults while distinguishing them from power swings, as validated through PSCAD/EMTDC simulations on a modified IEEE 39-Bus system.
