Non-linear loads are typically impacted by power quality issues since they are complex (PQ). The main factor contributing to condenser overload and poor performance is harmonic currents. In electrical systems with low power quality, voltage sags are typical. By using non-linear machinery like converters of power electronics, which raise the total reactive power output by an equivalent amount of an equal load, harmonic currents may be injected into the grid. The feeder voltage drops and losses rise when there is a significant demand for reactive power. Harmonic currents, which can result in low strength, can produce waveform distortions, such as voltage dips and other losses. The number of delicate loads that require perfect sine voltages has increased. Power conditioning solutions are becoming more popular as power-sensitive electronic gadgets are used more often. Power production must be compensated in some way if it is to stay within the advised ranges. One of the families of AC Transmission System Controllers, the Unified Power Quality Controller (UPQC) controls all transmission qualities including voltage, impedance, and phase angle (FACTS). This research focuses on innovative UPFC designs with increased power quality efficiency to reduce utility-provided voltage problems. Stress sales can be reduced by using a FACTS control like the Unified Power Quality Conditioner (UPQC). An UPQC series compensator handles the quadrature injection voltage. As a result, the compensator series uses zero active power at a steady state. A voltage injector is included in the suggested fix to make up for the system's subpar power quality. The voltage level is decreased and the power factor is increased by using a fluffy logic controller in addition to a regular UPQC. Additionally, the load factor has gone raised. The circuit is built and simulated using an MA TLAB/SIMULINK simulator. [ABSTRACT FROM AUTHOR]
