Development of a maximum power tracking unit integrated in wind turbine simulator

The purpose of our work is to study the maximum conversion of the wind power for a wind diesel system with battery storage using a wind turbine simulator (WTS). The maximum power point tracking have been achieved using a step down converter by controlling the output current of the permanent magnet generator (torque control). The current regulator used to achieve this goal is PI one. The regulation uses the PWM technique. The study was developed taking into account the wind speed variations. The complete model of the wind turbine and the PI current regulator were implemented in Matlab-Simulink environment and they were integrated in a WTS. The experimental results were obtained by using National Instruments acquisition station during a lapse of time of 9700 seconds
