Optimised yaw model for adaptive wind direction characteristic based on a data‐driven approach
IET Renewable Power Generation, 2021 The wind direction characteristics of different wind turbines (WTs) in different wind farms are diverse and some may have obvious differences. The WTs are prone to ‘over‐yaw’ and ‘under‐yaw’ conditions adopting constant yaw threshold and the same control
