Dynamic modeling and control of a wind turbine with MPPT control connected to the grid by using PMSG

Abstract

This paper work develops the dynamic model of a wind system based on a permanent magnet synchronous generator (PMSG). The dynamic modeling of the system requires prior knowledge of the parameters of the turbine, of the machine and of the static converters which are controlled by the pulse width modulation (PMW) to ensure the interconnection between the generator and the grid. Using a control approach called Field Oriented Control (FOC) based on optimum torque control (OTC) and using the Maximum Power Point Tracking (MPPT) method, the system can operate at a variable wind speed in an optimal way. The simulation results and the global system are simulated under the MATLAB / Simulink environment.
