Three Phase Four Switch Inverter Based DVR for Power Quality Improvement With Optimized CSA Approach

Industries driven by electric power require controlled and improved quality for the optimal exploitation of resources. However, certain crucial issues greatly influence quality, causing monetary losses to both utility customers. Numerous custom devices are available compensate issues; however, these alter parameters transmission distribution systems. Hence, a dynamic voltage restorer (DVR) is adopted in this study, which mitigates disorders establishing desired level demanded any sensitive load. The DVR adopts 3ϕ four-switch voltage-source inverter (VSI) that acts as cost-effective solution with reduced number switches. cuckoo search algorithm (CSA) was utilized study it solves multiple optimization ease implementation. Because robust variations system, significantly aids enhancing efficiency compensating minimizing total harmonic distortion (THD). entire work verified MATLAB/Simulink demonstrate effectiveness introduced technique smoothing distorted voltage. proposed approach achieved an 92.6%witha simulation THD 2.8% hardware 2.95%.
