The harmonic reduction methods were ineffective when employing conventional source current across various load conditions. Numerous reliability issues in harmonics mitigation stem from non-linear loads. Filters reduce harmonics and power quality issues. Because they offer a dynamic response under different load conditions, these filters are pricey. In addition to providing more secure power systems across a variety of load scenarios, the new Unified Power Quality Controller (UPQC) with its series and shunt compensator offers more efficient voltage stability. The reference current is generated from the AC source current using the Modified Synchronous Reference Frame Theory (SRF) theory. In contrast to load harmonics, SRF idea generates sinusoidal harmonics. In the PCC, this UPQC has the ability to inject or absorb reactive power. The DC connection capacitor receives voltage from a tuned PI controller that is based on the GWO Optimisation approach. The shunt and series compensator receive PWM pulses from the hysteresis current controller and D-Q theory.

摘要

The harmonic reduction methods were ineffective when employing conventional source current across various load conditions. Numerous reliability issues in harmonics mitigation stem from non-linear loads. Filters reduce harmonics and power quality issues. Because they offer a dynamic response under different load conditions, these filters are pricey. In addition to providing more secure power systems across a variety of load scenarios, the new Unified Power Quality Controller (UPQC) with its series and shunt compensator offers more efficient voltage stability. The reference current is generated from the AC source current using the Modified Synchronous Reference Frame Theory (SRF) theory. In contrast to load harmonics, SRF idea generates sinusoidal harmonics. In the PCC, this UPQC has the ability to inject or absorb reactive power. The DC connection capacitor receives voltage from a tuned PI controller that is based on the GWO Optimisation approach. The shunt and series compensator receive PWM pulses from the hysteresis current controller and D-Q theory. Lastly, we will use the MATLAB 2021a/Simulink programme to do a number of numerical simulations in order to validate the suggested controls. The THD output of the proposed UPQC parameter was found to be 1.4%.
