Constrained FCS‐MPC‐Based Current Controller for Voltage Source Converters: Application to Shunt Active Power Filters

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
In this paper, a constrained FCS‐MPC based current controller is introduced for controlling shunt active power filters. In the proposed current controller, the objective function is same as used in the conventional FCS‐MPC and a switching frequency constraint is considered to reduce the average switching frequency. The results obtained from FPGA in the

Servo Control of Shunt-Active Power Filters Using Kalman Filter With DC-Link Reference [PDF]

E3S Web of Conferences
LQG servo controllers may regulate current flow in a SAPF (shunt-active power filter) provided by a balanced or unbalanced supply voltage. Balanced or uneven supply voltages power the SAPF.

Model‐Free Predictive Direct Control of Unified Power Quality Conditioner Based on Ultra‐Local Model

IET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.
ABSTRACT To enhance the robustness of the unified power quality conditioner (UPQC) with finite control set model predictive control (FCS‐MPC), direct control in the dq coordinate system faces challenges such as complex coordinate transformation, system coupling issue and phase‐locked‐loop delays.

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 ...

Optimal design of a single-phase APF based on PQ theory [PDF]

, 2020
The instantaneous active and reactive power (PQ) theory is one of the most widely used control theory for shunt active power filter (SAPF), which can be implemented in single-phase and three-phase systems.

Low-Cost Active Power Filter Using Four-Switch Three-Phase Inverter Scheme

Electricity
Shunt active power filters (SAPFs) have been around for a long time. They improve the quality of a current drawn from the grid when feeding non-linear loads formed by old-fashioned power electronic converters such as uncontrolled and controlled ...

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.

Robust PSO‐Optimized Power Control for Stand‐Alone Variable‐Speed DFIG Wind‐Based High Stability and Power Quality Enhancement: Hardware Investigation‐Based dSPACE1103

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
Wind energy conversion systems (WECSs) operating in stand‐alone mode are increasingly recognized as a promising solution for delivering reliable renewable electricity in remote areas. However, their performance is often hindered by sudden wind speed fluctuations and parameter variations, which can compromise both stability and power quality. To address
