PQ issues, like voltage sag, voltage swell, harmonics, & flicker, due to the proliferation of nonlinear loads and renewable energy sources integrated with conventional systems. Using various control algorithms and switching strategies necessary including the conventional PI controller, hysteresis controllers, d-q theory of current, and the SRF theory to regulate voltage, mitigate harmonic distortions, and balance the system. UPQC has emerged as an effective solution to address these power quality problems comprehensively. Keyphrases: 1. Power Quality, 2. UPQC, 3. Shunt APF, 4. Series APF, 5. Hysteresis Current Controller, 6. SRF technique.
