In the recent years, model predictive control has been consolidated as a design strategy and an attractive alternative for the control of power electronic devices. This paper proposes an active and reactive power control strategy based on predictive control approach applied to grid-connected renewable energy systems. To accomplish this, a three-phase two-level voltage source inverter based topology is used in combination with a simple and efficient fixed-frequency modulation technique. Results based on a MATLAB/Simulink simulation environment are discussed and the most relevant characteristics of the proposed fixed-frequency predictive control approach are highlighted considering the total harmonic distortion as a figure of merit.
