Power Maximization Technique for Wind Energy Conversion System

In this study, a renewable energy conversion system is discussed. The bloc diagram consists of a small-scale wind turbine, a permanent magnet synchronous generator (PMSG), an AC-DC rectifier circuit, and a DC-DC Ćuk circuit which is controlled with a maximum power point tracking MPPT bloc that allows tracking the optimal rotor speed to make the system delivers the maximum possible power depending to the wind speed; this MPPT control perturbs parameters of the PWM signal that controls the MOSFET of the DC-DC circuit and observes the resulting power. Modeling of the systems’ components has been done following the mechanical and the electrical equations. The simulations have been carried out with MATLAB software; the obtained results confirm the effectiveness of the proposed configuration and show the reaction of the system with the MPPT control.
