| Summary: | The increasing use of power electronic devices has resulted in harmonics that may cause in power systems overheating of equipment, poor power factor and voltage distortion. Shunt active power filter (SAPF) provides the most useful means for harmonics mitigation in power systems. In a certain number of SAPFs, the dc link capacitor voltage is regulated by means of a PI controller. This paper proposes a variant of a population based Jumping Spider Algorithm for optimal tuning of the PI controller to enhance the performance of the active filter. The SAPF considered in this paper uses the p-q theory to extract its reference current and the hysteresis current control to produce the triggering signals for the controlled switching devices of its inverter. The overall SAPF is developed and validated using MATLAB/Simulink tool under two different nonlinear loading conditions. The results obtained by simulation show that the SAPF with the proposed PI controller effectively controls the dc-link capacitor voltage and mitigates current harmonics. |
