Abstract: This research presents a new approach to address issues related to power quality that manifest in new ways, a control technique known as synchronisation reference frame (SRF). By employing a self-tuning filter in conjunction with the unit vector generation method (STF-UVGM), synchronisation between phases is obtained while UPQC remarkably demonstrates its performance, even in the case of imbalanced or distorted supply voltages. Consequently, there is no longer a necessity for phase-locked-loop, low-pass filters, or high-pass filters. Nevertheless, a self-tuning filter remains employed to separate harmonic and fundamental components. Furthermore, STF-UVGM has been implemented for generating synchronisation phases within the shunt filter. The performance evaluation of PV-UPQC has been extensively explored across three test cases involving different loads and supply voltages; in all scenarios, this proposed methodology exhibits exceptional efficiency as it effectively reduces total harmonic distortion (THD) and mitigates voltage distortions. The proposed PV-UPQC successfully reduces the current and voltage harmonics, as shown by the MATLAB simulation results.
