Abstract
This article examines the proportional-integral (PI) and fractional-order proportional-integral-derivative (FOPID) controllers for a quasi-buck converter-hybrid active filter (QBC-HAF) to improve the harmonic suppression and power quality of a hybrid energy storage system (HESS) fed to the grid. This system uses a high-gain QBC, which is connected to a VSI to control the DC-link voltage and to allow controlled energy transfer from photovoltaic and battery sources. A MATLAB/Simulink test bed and hardware prototype were developed to validate performance. The results demonstrate the enhanced stability and quality of the output waveforms for both controllers, with the FOPID providing better harmonic suppression, reducing output current total harmonic distortion (THD) from 4.34% to 4.14% and output voltage THD from 4.75% to 4.42%. The simulation results were validated using experimental tests, showing that the FOPID-controlled QBC-HAF system is suitable for power quality improvement, voltage stabilization, and dynamic performance in renewable integrated grids.
This work focuses on the modelling and simulation of a Proportional Resonant (PR) current controller designed to mitigate, to an acceptable limit, the current harmonics that distort the output current of the Voltage Source Inverter (VSI) tied to the utility grid. To achieve this, an LCL filter was designed to filter ou...

In order to improve power quality in low-voltage distribution networks with nonlinear, distorted, and unbalanced loads, this research suggests an innovative design for Shunt Active Power Filters (SAPFs). Compared to conventional single-inverter SAPF structures, the improved method uses a combination of two T-Type three...

This paper presents an experimental investigation of a dual-inverter induction motor (IM) drive system for zero-sequence circulating current (ZSCC) suppression using a novel hybrid PI–SO-SMC strategy. The proposed method combines a proportional–integral (PI) regulator and a second-order sliding mode controller (SO-SMC)...
