“…Validating and enhancing the control of wind turbines requires a test bench environment. Wind turbines are known to exhibit nonlinear behavior. A wind turbine emulator is an essential tool for modeling a real wind turbine's static, dynamic, and nonlinear properties without relying on available natural wind resources or commercial wind turbines. Authors in [19] and [20] used the Dspace card to realize a hardware under-loop simulation. As a perspective in their study, authors in [21] plan to conduct experimental tests after realizing the hardware in the loop. ….”

Please explain the selection of the wind step profile from Figure 10.
Thank you for pointing this out. In order to evaluate the control method, the authors used two different wind profiles. The first profile(figure 10) is a step profile to simulate abrupt changes in the machine to assess its robustness.

Reviewer 2 Report
The novelty of this work aims to design a new wind emulator and design a power control approach for a Doubly Fed Induction Generator based wind system. Minor revisions are recommended before publication. The specific comments are as follows.
1. The DFIG in the abstract needs to be clearly expressed in terms of what it means. The suggested format is: Doubly Fed Induction Generator (DFIG). This will make it easier to read.
2. Citations need to be standardized. For example, [36]
3. Figure names need to be standardized. For example Fig.1 or Figure 1.
4. Figures 17-19 are not clearly presented, and it is recommended that the data be extracted and redrawn. And other similar figures in the paper should be corrected.
5. The coordinate titles of all figures need to be in a uniform font. The content of all images in the article needs to be modified.

Reviewer 3 Report
1. Some typographical and grammatical errors of this paper should be carefully checked and corrected.
2. Motivation of this work should be properly mentioned in the introduction section.
3. It is suggested to presents some results in tabular form for better understanding and comparison purpose.
4. Journal Standard reference format need to be followed for this paper.

Reviewer 4 Report
Thanks for the esteemed authors for their submission. The paper presents useful contribution for the field of real time control of wind turbines. However, those comments are suggested to improve the paper originality and clarity:
- Modify the title to include "Power" not "Powers".
- State clear definition for the Pitch angle in the introduction/background section before the literature review.
- What is the value added over what has been published in reference [34]? and this reference as well https://ieeexplore.ieee.org/document/8807498
- Reword the contribution clearly according to point 3 that I mentioned.
- What are the MATLAB solver and the step size required for real time simulation?
- In figure.8, I think the arrow direction should be from DFIG to the inverter, not the reverse. Incorrect figure drawing should be fixed and check carefully other figures.
- Reorganize the paper into sustainability MDPI template and follow the guidelines.
- Figures 12 and 13 should be preferably on a landscape page.
Best wishes for the authors
