  Wind is a convenient and powerful source of energy. Power generation in a variable speed wind turbine is an interesting topic; since in wind energy converter systems, maximum utilization can be achieved at any speed. But this system needs its parameters to calculate the optimal speed of the turbine. In this article, a control method for tracking the maximum power point in the wind energy converter system is presented, which has been used for simulation and design along with fuzzy control by Mamdani method. In this article, the wind energy converter system is a two-fed induction generator, which is connected to the grid with a rotor and a stator. The input of the control system is the difference between the desired speed of the generator and its actual speed. The optimal speed is the rotational speed at which the generator receives the maximum power from the wind turbine. After conducting simulations and designing a suitable fuzzy controller for the system, it was found that the incorrect selection of a parameter has an adverse effect on the control process of a system.

  Doubly fed induction generator has numerous advantages in wind power generation over other types of generators. Once a DFIG is subjected to a large voltage dip, a large rotor voltage induces in the rotor windings. This leads to a large transient current in rotor circuit and the dc-link overvoltage, and may block power electronic converter operation. This paper first discusses dynamic modeling of  DFIG wind turbines with the stator flux orientation. Then, by small signal analysis, it is found that the dynamic behavior of the DFIG based WT during voltage dip, is strongly affected by the stator dynamics. Next, a nonlinear control strategy based on flatness is proposed to improve the DFIG transient performance. The main interest of this control method is the possibility to define the behavior of the state variable system in the steady state as well as in transients. Since the DFIG electrical dynamics are nonlinear; better control performance is achieved with nonlinear control, compared with the linear control scheme. The proposed approach stabilizes the stator dynamics through rotor and grid side filter voltage control. The results of time domain simulations validate the effectiveness the nonlinear control strategy during voltage dip of generator terminal. Manuscript profile
