Model predictive control of STATCOM for grid voltage regulation

Abstract

In this paper, a predictive control method known as FS-MPC is raised to adjust the grid voltage by STATCOM. The FS-MPC control strategy is easy to implement that considers nonlinearities and limitations as well. In this way, the system model is used to predict the current behavior in the next sampling period for each possible switching mode. The STATCOM is simulated using the FS-MPC control method by MATLAB SIMULINK, and compared to conventional PI-controller accompanied with the PWM. The results of simulations represent considerable improvement in the performance of the FS-MPC control method for adjusting the grid voltage variations.
