Problem: Wind turbines often run 8 or more PID loops, and many of them have strong interactions. This causes manual tuning to give sub-optimal results. Solution: An automatic tuning tool which optimizes all the controller parameters w.r.t. the loads, and the power. Result: The time required to fully optimize the control loops is reduced from two weeks to just two days.
Problem: Wind turbines operate at a yaw error of about 6 degrees on average. Solution: An Artificial Intelligence method to find the yaw angle that optimizes the power production. Result: Increase in power production of 1.5%.
