Abstract: This paper present the SMC (Sliding Mode Control) With Proportional-Integral (PI) controller which is used for DSTATCOM for improving current induced power quality issues. The advantages of using SMC for regulating the DC link voltage of DSTATCOM are reduction in number of sensors for estimating reference currents and the stability of DC link voltage during transient condition. The use of PI controller for terminal voltage gives the error free voltage regulation in steady state conditions. The voltage regulation feature of DSTATCOM offers various advantages such as single point voltage operations with the reactive power compensation, harmonic currents mitigation, and stable DC link voltage. The SMC algorithm is successfully implemented on a DSTATCOM employed with three phase loads. The performance of the proposed control algorithm is found satisfactory for voltage regulation and mitigation of power quality problems like reactive power compensation, harmonics elimination under nonlinear/linear loads. These schemes are simulated under MATLAB using SIMULINK and Sim Power System (SPS) toolboxes. Simulation and experimental results demonstrate the performance of these schemes for the control of DSTATCOM.
