Abstract: Wind energy is recognized as one of the most advanced and promising renewable energy sources. To connect a Wind Energy Conversion System (WECS) to either a load or the utility grid, an essential power electronic interface is required. This interface comprises generator- and grid-side converters, and their control presents significant challenges. The primary objective of controlling the generator-side converter is to implement Maximum Power Point Tracking (MPPT). In this project, the conventional Hill Climbing Search MPPT algorithm has been refined using logic theory, which enhances its performance in both accuracy and speed. This modified algorithm enables the system to continually extract maximum energy from the wind by generating an optimal rotor speed reference. The Vienna rectifier is selected as the generator-side converter due to its substantial advantages in WECS applications. For effective speed control, a non-linear control scheme based on Sliding Mode Control (SMC) is employed, demonstrating notable benefits over traditional linear controllers. Simulation results validate the efficacy of both the control scheme and the modified MPPT algorithm. Furthermore, a comparative analysis between SMC and MPPT controllers is conducted, focusing on their speed control performance. Through innovative control strategies and algorithm enhancements, this project significantly contributes to the optimization of wind energy conversion systems, ensuring more efficient and reliable harnessing of wind power for sustainable energy generation.
