Reviewer 2 Report
Comments and Suggestions for AuthorsThe article addresses the topic of renewable energy, an important subject, but there are some points to note about the work. The most prominent of these are:
- On line 36, avoid using multiple references as supporting evidence. Two or more references are sufficient. The same applies to line 58.
2. The topic of renewable energy, particularly wind energy using PMSG or DFIG generators, has been extensively covered. Therefore, the introduction section needs to highlight as many works as possible that have addressed this topic, while also identifying and discussing the existing gaps in knowledge.
3. The contributions of this paper are unclear in the introduction section. It is essential to define these contributions along with the aims and objectives of this work.
4. Please review the abbreviations in the text.
5. Include a list of abbreviations to simplify understanding and reading the work.
6. On line 172, Figure 2(b) is not in the article. Please review the numbering of figures within the text.
7. On line 193, Figure 3 is in the main body of the article but not in the Appendix. This figure requires further explanation.
8. Equation (7) needs further explanation.
9. How was the condition included in Equation 9 proven? Please provide a detailed explanation.
10. The control shown in Figure 5 lacks any details. Is it a new control? Or is it a control whose effectiveness has already been proven? References are needed.
11. In Figure 9, how is stability proven? It is not proven.
12. Please add a robustness test to the designer's approach.
13. What about the system's response at cut-in and cut-out speeds?
14. Please extract numerical values ​​such as response time, ripple, overshoot, etc.
15.Write the references according to the journal's policy.

Reviewer 3 Report
Comments and Suggestions for AuthorsThe topic and the supporting documentation are interesting and can be considered for further review steps. My review comments are as follows:
I. The abstract and conclusion sections lack numerical results. The authors need to add numerical outcomes of the software analysis, such as the tested power rates, THD values, harmonics, and suppressions expressed in percentages, voltages, and currents, etc.
II. The literature review and introduction sections can be expanded. They contain less material and explanation than expected.
III. The authors need to include an abbreviation subsection and introduce all parameters used in the equations. Some parameters, such as HPLL(S) or Vm, appear without the necessary explanations.
IV. The integration of different wind turbines considering their generated power rates is a complex process. The authors do not emphasize grid integration, although the topic suggests that this aspect will be addressed. They need to add explanations regarding the difficulties and provide suggestions for their proposed system in terms of grid connection.
V. The authors should explain the disadvantages associated with different phase angles formed due to parallel impedance. It also seems that other parameters, such as differences in voltage magnitudes, pose more serious problems. The authors need to clarify this.
VI. The impact of energy transmission lines should be considered in the model.
VII. A table summarizing similar studies should be prepared, and a detailed comparison of the proposed control systems should be presented. Parameters such as accuracy, complexity, efficiency, feasibility, and controller cost can be compared.
