Crack Segmentation Model Based on Deformable Convolution and Cross‐Stage Feature Fusion Network

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
YOLO‐RCS, an enhanced crack segmentation model based on YOLOv10, is designed to improve the detection of multi‐scale cracks in complex environments. By integrating a DCNv4 backbone and a novel C3FB module, our model achieves high precision and mean average precision (mAP) for road crack segmentation, addressing issues of missed and false detections ...

Control of Photovoltaic‐Based Shunt Active Power Filter System Based on Optimal Operating Point Tracking of PV System for Harmonic Mitigation, Load Supply and Grid Current Injection

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
The proposed control strategy combines a search algorithm to find the optimal operating point for the photovoltaic system and a harmonic identification technique. The OOPT algorithm regulates the operating point to achieve an optimal trade‐off between photovoltaic power production and the desired functionalities.

Selective harmonic suppression strategy by SAPF in power distribution system

The Journal of Engineering, 2017
This study proposes a flexible selective harmonic compensation and resonance damping algorithm for shunt active power filter (SAPF) applied in three‐phase three‐wire power distribution system. The selective harmonic compensation current reference extraction is based on recursive discrete Fourier transform.
