Power Quality Improvement in Power System Network using Unified Power Quality Conditioner

Power Quality issues in AC distribution systems, such as harmonics, voltage sags/swells, and unbalanced loads, are increasing due to rising non-linear loads. Unified Power Quality Conditioner (UPQC) effectively mitigates these issues through combined series and shunt compensation. It enhances power quality by reducing harmonics and voltage disturbances. MATLAB simulations validate UPQC performance in a three-phase R-L load distribution system.
