Abstract Power quality issues are gaining significant attention due to increase in the number of loads. In fact, voltage sags problem is the most occurring power quality problems. These events are usually associated with a fault somewhere on the supplying power system. Therefore, the aim of this study was to assess the applicability of Distribution Static Compensator (D-STATCOM) for the mitigation of voltage sag problem. Three methods were used in control to get the performance of mitigating voltage sag, namely Genetic Algorithms (GA), Fuzzy Inference system (FIS), and Proportional Integral (PI) to determine the injection of voltage and comparison of timely responses. As a result, D-STATCOM injected the voltage into the distribution system to recover the voltage sag problem at single-phase, two-phase, and three-phase fault scenario. The results showed that Genetic Algorithms were capable to overcome the voltage by 98.50%, 98.40%, and 94.15% in single-phase, two-phase, and three-phase appropriately. On the other hand, Fuzzy Inference System was capable to overcome the voltage by 98.15%, 92.15%, and 90.75% in single-phase, two-phase, and three-phase appropriately. While, proportional Integrative was capable to overcome the voltage by 98.05%, 85.80%, and 80.00% in single-phase, two-phase, and three-phase appropriately. Among them, the best performance was obtained from the Genetic Algorithms method in order to mitigate voltage sag. Consequently, D-STATCOM was substantiated as a fancy compensator for the reactive power requirement of the load. Furthermore, it is to be hoped that in future this proposed distribution system device will be established as a new proficient customer power device commercially.From the result analysis, it can be concluded that GA showed to be a better performance for solving voltage sag problem than FIS and PI controller.
