Power Quality Improvement using Three Phase Four Switch Inverter Based Dynamic Voltage Restorer with Ant Colony Optimization

electricity is one of the goals of electric power networks. Any disruption to electrical distribution networks results in voltage disruptions. Therefore, to minimize these disruptions for sensitive clients, a range of tactics and instruments may be employed. Dynamic voltage restorers, or DVRs, are applied in this work to handle sensitive loads’ voltage swings. Ant Colony Optimization (ACO) is used to manage the coefficients of PI controllers in order to optimize voltage sag and THD in sensitive loads at the same time. The entire project was validated in MATLAB/Simulink to demonstrate how successfully the suggested solution smoothed the distorted voltage. The proposed ACO technique achieved a higher efficiency of 95.6% with a reduced THD of 1.16% when compared to the Cuckoo Search Algorithm (CSA).
