Voltage fluctuations is a major power quality problem has a significant impact on both the equipment and production environment. This research describes the voltage control technique of mitigation of voltage fluctuations and clearing fault using Distribution Static Synchronous Compensator (D-STATCOM). The test system used is the IEEE 9-bus distribution system clarified the optimal location of D-STATCOM by using an Artificial Neural Network (ANN). A simulation was done using MATLAB/Simulink Software. Keywords: Power quality;voltage fluctuation;D-STATCOM;power distribution system;ANN
