Adaptive Wide‐Area Damping Control for Local Oscillations Induced by Grid‐Forming Converters and Frequency‐Sensitive Loads

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This paper investigates local oscillations caused by interactions between grid‐forming converters and frequency‐sensitive induction motor loads. A unified small‐signal model and frequency‐domain analysis reveal that high load factors and low motor inertia can lead to weakly or negatively damped oscillation modes.

An Overcurrent Suppression Strategy for Distributed Photovoltaic Inverters Under Unbalanced Faults Based on Adaptive Linear Active Disturbance Rejection Control

IET Smart Grid, Volume 9, Issue 1, January/December 2026.
After distributed photovoltaic (PV) systems are connected to the distribution network, the overcurrent problem caused by transient faults instantaneously threatens the safety of PV inverters and other equipment. This paper proposes a comprehensive control method that combines active‐loop adaptive linear active disturbance rejection control (A‐LADRC ...

On‐Demand Schedules, Worker Absenteeism and Patient Dissatisfaction in Home Care Services

Journal of Operations Management, Volume 71, Issue 8, Page 1090-1114, December 2025.
ABSTRACT Service companies often adopt on‐demand scheduling to balance labor costs and fluctuating market demand. However, research shows that such practices can reduce worker productivity and retention. In this study, we examine how on‐demand scheduling affects two critical outcomes: worker absenteeism and patient dissatisfaction.
