PULSED LASERS IN LIDAR APPLICATION: MODELS FOR OPTIMIZING WIND TURBINE PERFORMANCE

Abstract:
Wind energy is an increasingly important source of renewable power generation. Wind turbines play a crucial role in converting wind energy into electricity. However, the performance and efficiency of wind turbines are greatly influenced by the complex and dynamic nature of wind flow. To optimize wind turbine performance, accurate and real-time measurements of the wind characteristics are essential.

Light Detection and Ranging (LIDAR) technology has emerged as a powerful tool for wind resource assessment and wind turbine control. Pulsed lasers, specifically designed for LIDAR applications, offer unique advantages in capturing detailed wind information. This abstract focuses on the utilization of pulsed lasers in LIDAR systems and the development of models for optimizing wind turbine performance.

Pulsed lasers emit short-duration, high-intensity laser pulses, which are directed towards the atmosphere. By analyzing the characteristics of the backscattered laser light, LIDAR systems can measure wind speed, direction, turbulence, and other important meteorological parameters. These measurements provide valuable insights into wind flow patterns and enable the implementation of advanced control strategies for wind turbines.

This abstract also highlights the development of models that utilize LIDAR measurements to optimize wind turbine performance. These models integrate LIDAR data with computational fluid dynamics (CFD) simulations, control algorithms, and turbine response models. By assimilating real-time LIDAR data into these models, wind turbine operation can be optimized, leading to increased power capture, reduced loads, and improved overall performance.

The proposed models consider various factors, including wind shear, turbulence intensity, wake effects, and yaw misalignment, to accurately predict wind conditions at the turbine rotor and optimize control actions. By employing advanced control strategies based on LIDAR measurements, wind turbines can adapt their operating parameters in response to changing wind conditions, maximizing energy production while minimizing structural loads and maintenance costs.

This abstract emphasizes the potential of pulsed lasers in LIDAR applications for wind turbine optimization. The integration of LIDAR technology with advanced modeling techniques holds great promise for enhancing wind turbine performance, improving energy production efficiency, and reducing the levelized cost of energy. Future research in this area should focus on refining the models, incorporating machine learning algorithms, and conducting field validation studies to further demonstrate the effectiveness of this approach.
