This paper describes the modeling and the optimal tuning of PI control techniques of distribution static synchronous compensator (DSTATCOM) using PSCAD/EMTDC package. Moreover it is presented to make the model of IEEE 13 bus radial distribution power system and applied to the model of DSTATCOM using PSCAD/EMTDC. Using Optimal tuning PI control, the voltage sag as well as the fast dynamic response is achieved. The derived simulation is tried to verify the result of this paper.
