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

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.
