Abstract
To optimize wind farm layout and micro-siting, this study analyzes the impact of different numbers of small wind turbines on the wake region of a large wind turbine at varying yaw angles. It also explores the periodic characteristics of wind speed signals at different time scales. The study involves one large and nine scaled-down small wind turbines in a 3 × 3 arrangement to simulate real-world interactions. The results reveal that increasing small turbine numbers significantly amplify wake deficits downstream, intensifying periodic oscillations, providing crucial theoretical support for wind farm design optimization. These findings contribute to understanding complex wind turbine dynamics in wind farms and supporting future efficient and sustainable designs.
