Abstract: Due to the wind speed variation, wind shear and towershadow effects, grid connected wind turbines are the sources of power fluctuations which may produce flicker during continuous operation. This paper presents a model of an MW-level variablespeed wind turbine with a doubly fed induction generator to investi-gate the flicker emission and mitigation issues. An individual pitch control (IPC) strategy is proposed to reduce the flicker emission at different wind speed conditions and also extend, an advanced pitch angle control strategy based on the fuzzy logic is proposed for the variable-speed wind turbine systems. The fuzzy logic controller is employed for change blade angle of wind turbine and constant power can be achieve. The block diagram of proposed pitch control which consists of pitch controller, actuator model and turbine linearized modeled by using Matlab/Simulink software.
