Power quality is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure of end use equipment's. In order to maintain the power system quality the DSTATCOM will absorb and provide reactive power to mitigate voltage sag, swell, interruption and improve power factor in various conditions. The proposed scheme exhibits several advantages compared to traditional voltage-controlled DSTATCOM where the reference voltage is arbitrarily... This scheme allows

The performance of DSTATCOM is found satisfactory under time varying and unbalanced loads. Its performance is simulated in the MATLAB environment using SIMULINK and Sim Power System (SPS) toolboxes
