Model Predictive Control for Shunt Active Power Filter Under Both Balanced and Unbalanced Grid Conditions

In this paper, a refined reference current generation based on synchronous reference frame (SRF) together with model predictive control (MPC) current approach for three-phase shunt active power filter (SAPF) under balanced and unbalanced grid conditions is presented. The reference current computation method is based on the use of phase-locked loop (PLL) system. The performance of the proposed method is obtained by means of computer simulations using Matlab/Simulink.
