Research on Optimal Voltage Control of Distribution Network with the Participation of EVs and PVs
Round 1
Reviewer 1 Report
- Please compare advantages/disadvantages of other approaches etc. It would be good to have a comparison with some already presented control scheme.
- Where the research is headed in future ? It would be nice to add a paragraph or some lines regarding the future prospect of the research.
- It would be nice to have some more references in text.

Reviewer 2 Report
Dear Authors,
After reading the article, I conclude that it needs significant revisions. First of all, the data presented is often unsupported by any sources. In lines 25-62 there are no references to the literature, making it impossible to verify the data. Next, in Table 1, what were your thoughts to assume such and not other SoC parameters?
In formulas (14) and (15), the efficiency of the charging process was not taken into account, which is a common component in the literature.
My main concerns relate to the verifiability of the proposed model. Has a sensitivity analysis been performed? From what is the assumed power of PV installations and charging parks? From what is the assumed number of EVs derived? Are these vehicles characterized in some way? What is the battery capacity? Why was the SoC at the end of charging assumed to be 95% and not 85%/100%? Are the relative units given in Figures 12 and 14 when it comes to the load profile? The same goes for considering marginal power loss costs. What do they result from? If the same model is applied to real networks, will it be possible to verify these parameters on it? What are the operating costs of using OLTC mentioned in this sentence: "minimize the daily operating costs consisting of the costs due to power losses and the utilization costs of OLTC transformers and CBs, as in (19) and(20)."??
The article contains a large number of grammatical and stylistic errors. It should be rewritten. The descriptions of the formulas lack units, which also does not help to facilitate analysis.
In my opinion, the article should be revised and authors should think about the universality of application, especially in the economic field - perhaps sensitivity analysis will help solve this problem.

Reviewer 3 Report
The article entitled “Research on Optimal Voltage Control of Distribution Network with the Participation of EVs and PVs” is interesting. However, there are some major concerns as follow:
1. Line 14- Abstract- Suggest the authors to remove the word “fully” from the sentence. To “exploit” is sufficient. “Fully” seems like overclaim.
2. Abstract-What is the main finding of this study? Since this manuscript is a scientific paper, measurable findings/ conclusion shall be included.
3. Introduction- The objective of the study is to propose a two-stage control scheme for the voltage regulation of distribution networks. However, what is the novelty/ gap of study? Would suggest authors to highlight the gap/ contribution/ novelty in introduction section.
4. Figure 12 and Figure 13- The critical discussion on the figures are required. What can authors deduce from the plotted chart? Would suggest authors to elaborate and provide in-depth discussion. Also, legend is needed.
5. Details discussions are required. Current form is too short, and the content is insufficient. Authors shall heavily edit this section so that further comments could be provided.

Round 2
Reviewer 2 Report
Dear Authors,
Thank you for your answers to the questions. However, I would like to see a methodology for determining the parameters {lambda2 and lambda3} in the article. I appreciate the addition of a text description, nevertheless I cannot find a relationship between "their equipment investment costs and expected lifespans". What is the relationship between these parameters? Why only CAPEX is taken into account, and OPEX in the form of at least the cost of installing such equipment, the cost of service inspections, etc. is not considered.
I would also ask you to clearly indicate that the cases studied are those for the most extreme conditions. Also, what is the reason for the close placement of PV installations in the test grid? Was this intentional or random?
