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

open access: yesIET 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

open access: yesJournal 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.

Three-vector model predictive power control of doubly fed induction generator based on linear extended state observer under unbalanced grid

open access: yesInternational Journal of Electrical Power & Energy Systems
Doubly-fed induction generator (DFIG) is susceptible to unbalanced grid voltage and mismatched motor parameters during grid-connected operation. The conventional model predictive control (MPC) has low complexity and fast dynamic response, which is widely
