Wind energy is a sustainable and environmentally friendly source of power that has recently been the subject of abundant research aimed at maximizing its practical application. The primary benefit of wind turbine systems is enhancing the turbine's design and performance. Modeling by the graphical user interface of MATLAB provides a clear picture of the wind turbine's efficacy in a real-world scenario. This study investigates a horizontal-axis wind turbine with a variable pitch mechanism. The wind speed and pitch angle were manipulated in MATLAB-Simulink to simulate the turbine. Variables such as wind speed and angle of attack influence the active power output of the turbine. The results indicate that the optimal wind turbine characteristics, including pitch angle and turbine speed, are attained at different wind speeds. Consequently, through the process of simulating and analyzing the outcomes, it is ascertained that the turbine attains its maximum active power output when the pitch angle is optimized.
