Performance analysis of UPQC for total harmonic distortion

In order to mitigate power quality (PQ) issues in electrical power systems, the Unified Power Quality Conditioner (UPQC) is the main topic of this research study. Power Quality problems, such as voltage sag, voltage swell, harmonics, and flicker, are brought on by the increase in nonlinear loads and the integration of renewable energy sources into traditional systems. Employing a variety of control algorithms and switching techniques, including as the SRF theory, hysteresis controllers, d-q theory of current, and traditional PI controllers, to balance the system, control voltage, and reduce harmonic distortions. For the reduced harmonic distortion, a FFT analysis is done so that the quick response and stability is ensured. UPQC has shown to be a successful method for fully resolving these power quality issues.
