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

Adaptive Frequency-Based Reference Compensation Current Control Strategy of Shunt Active Power Filter for Unbalanced Nonlinear Loads

Energies, 2019
The shunt active power filter (SAPF) is an effective means for the modification of power quality. However, the compensation performance of SAPF would be deteriorated when the unbalanced nonlinear loads are present in the power system.

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.

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
