The manuscript entitled “Scaled testing of maximum-reserve active power control” presents significant findings in the field of wind farm control.  The paper is well written, with the objective and outcomes of the study clearly explained.  However, there are some critical points that require further discussion: 

- A deeper discussion of the timescale is needed: we know that time in the wind tunnel is accelerated and that the TI is 6%. Please discuss which real-world wind farm conditions this can represent. 

- Explain how the real-time wind direction histories have been rescaled and adjusted for the experiment. 

- The different controllers use bandpass frequency filters. Please explain how these frequency bands can be adjusted in real applications involving large multi-MW turbines. 

- When discussing fatigue loads for single wind turbines in different scenarios, you should also analyse how these loads could affect the residual useful life of the entire wind farm and its maintenance programme. 

- Figure 21 is crucial for understanding the various control strategies. Please improve it by adding more zoomed slices to make all the parameters clearer especially for highlighting saturation.
