The concept of this paper is to control the active power and reactive power for three-phase grid-connected inverters. Here,
we have the proposed that the control strategy of Model Predictive Control (MPC) be used instead of pi controllers.
Comparing with traditional current control methods, a linear model of the load is needed to adjust the pi controllers. In
the case of MPC, it will calculate predictions for each voltage vector, a discrete model of the load that does not need to be
linear. The performance of the pi controllers depends on the
values, and their adjustments. There are no parameters
to adjust in MPC, but the cost function must be defined. And the proposed method MPC has a better dynamic performance,
,
and it will give transient dynamics recovery time and overshoot will have been considerably improved. Conclusively, the
simulation results are allowed to confirm the efficiency of the proposal.
