[交流] tie给了大修，与原文章重复度较高

5个reviewer，其中一个和AE比较犀利。小白心态有点崩，请问大家遇到这种情况是怎么处理的。

Reviewer: 1

Comments to the Author
1- The language of the manuscript must be improved.
There are many loose sentences, which are both structurally and grammatically incorrect. Also, There are several typesetting and grammatical mistakes in the manuscript, and the write up is not good.
2- Why you discuss about current source inverters?? These inverters? are rarely used in grid-connected systems.
3- In relation to the previous comment, all reviewed papers are about the voltage source inverters.
4- Equation (33) is lost.
5- All figures have low quality and can not be used.
6- Why the grid impedance is ignored? In weak grid condition, it may affect the system stability.
7- The sampling frequency range in table 1 must be checked.
8- Why the effect of the integral term in the PR controller is ignored on the system stability?

Comments to the Author
This paper’s examination of different delay’s impacts on the stability of grid-tied CSI is valuable.? Many of the analytical analysis are sound, and the experiment results have been presented to exam the stability of the system. （格式问题比较多，我删了一些）
However, I have following comments and recommendations:
.
5. Pg. 3, Line 23-41:? the description here is not clear.? You are discussing some theory from stability analysis.? Please make sure you cite appropriate references here.? In addition, please provide description for all the undefined variables like L(w), phi(w).

6. Pg. 3, Eq. (7): why when w=wres, it is positive infinity?? There is still jCrw in the denominator.

7. Fig. 5:? I recommend you add word description in Fig. 5 to show the two bode diagram lines that are stable.

15. Fig. 7: please add arrows in the figure to show the root loci with respect to the variation of lambda.

16. Pg. 7, Line 26: “a method for suppressing…” is confusing.? I think you have not proposed any new method in this paper; instead, you are designing controller in the stable region you evaluated.

17. Grammar issues:? there are multiple grammar issues throughout the paper.? Please carefully read through the paper and correct the errors.?

1. Please correct double-check the paper for typos such as “controlof” and “controlis”.
2. For grid-connected inverters, LC and LCL filters are more popular. Are the results presented in the paper sill applicable to these types of filters?
3. As its name suggests, grid-connected inverters are often tied to a grid whose impedance might vary significantly depending on operation conditions. How could a weak grid be considered in the analysis?
4. The current controller is simplified as a proportional gain. Could the author justify such as simplification?
5. It is suggested to point out the application of the paper. Generally, the switching frequency, delay, and resonant frequency are chosen considering the specifications of the system hardware and grid interconnection requirements.

This review has some remarks as follows:
- in Section III (A) is repeated paragraph ?The control block … the following formula (11)”,
- in Section II (B) is incorrect reference to the Fig. 3.,
- in Section III (A) equation nr 33 is not numbered,
- there is a few symbols in the paper with wrong format (without italics),
- the author(s) should present additional figure with a real photo of the test bench,
- the Figures 3, 5, 8, 9- 14 should be presented more clearly (larger fonts mainly),
- there is a missing Fig. 7 reference (?As shown in Fig. (a) and (c)…”),
- the author(s) refer(s) to the works, where general ranges of time delay for stability are provided for specific regulator parameters. Please present the new contribution more clearly. How the author(s) choose or calculate kp, or it is negligible in presented method? The author(s) should present: used parameters of regulator, and additional experimental result for different kp values if it has significant influence,
- some sentences should be better worded, please improve your written English.

Comments to the Author
The presentation of the work and the method of tackling the problem are both similar to those of [35]. The authors must acknowledge this explicitly if they are not prepared to make significant changes.
1. The first and second paragraphs of Section III-A are same.
2. Where is the study of ‘the influence of the equivalent resistance’ as stated in the text following (18)?
3. (33) is missing.
4. A photo of the hardware system needs to be presented.
5. Where is the work of ‘suppressing system resonance’ as stated in the last paragraph of Section IV?
6. The references should be updated, as most of them are published before 2015.
7. The written English should be improved

Comments to the Author:
This paper has many problems. Its contents are very similar to [35]. Especially, most of the equations are exactly same as in [35] which shows that the paper lacks novelty. In addition, the reviewers have raised many comments regarding many issues such as grammar mistakes, organization of paper, quality of figures, etc.
