Model Predictive Controller (MPC) is described in this paper for the improvement of power quality in Microgrids. Microgrid is a low voltage grid which is subjected to disturbances. The distributed energy resources are connected to the LV bus by means of power electronic converters. The power quality issues are analyzed with MPC control algorithm in both- Grid connected & Islanded modes. But the Islanded mode is analyzed separately. Predictive control based Distribution static compensator (DSTATCOM) injects voltages at the point of common coupling (PCC) in the Microgrid. Reactive power compensation is done with two linear & one non linear load in both modes of operation. The principles and the proposed algorithm are verified by MATLAB/SIMULINK simulation. Simulation results suggest that this control method can decrease the power quality issues and increase the microgrid stability.
