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.

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.

Segment Reduction‐Based SVPWM Applied Three‐Level F‐Type Inverter for Power Quality Conditioning in an EV Proliferated Distributed System

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
The objective of this paper lies in the realization of a three‐level F‐type inverter (3L‐FTI) as a shunt active filter in an EV‐proliferated environment. The switches are triggered using segment reduced space vector pulse width modulation (SVPWM). This modulation technique provides a lower number of switching transitions than existing PWM strategies ...
