This paper gives Simulink modeling of improved hybrid distribution static compensator (DSTATCOM) methodology tocompensate reactive and nonlinear loads with reduced VSI rating, DC link (capacitor) voltage and filter size. An LCL filterwith less value of inductor compared to old L filter is used at the front end of a voltage source inverter (VSI), which gives themitigation of switching harmonics. Voltage of the DSTATCOM can be reduced with capacitor to be connected in series withan LCL filter. The power rating of the voltage source inverter (VSI) has also been decreased. With reduced dc-link voltage,the voltage across the capacitor connected in parallel with the LCL filter will be also less. It will minimize the power lossesin the damping resistor as compared with the old LCL filter with passive damping. A systematic procedure of DSTATCOMcontrolling and filter designing has been presented. The advantages of the proposed DSTATCOM methodology over oldmethodologies is validated through simulation.
