Research on Optimization Method of Integrated Energy System Network Planning
Round 1
Reviewer 1 Report
The article presents a case study of how to optimize the integrated system energy planning based on "economy, energy savings, and environmental protection". The optimization method and results are presented in the manuscript, but with all these, there still are several observations that authors must consider. Please find the comments below and in the attached file.
Please use the latest template of the journal.
Overall, many sentences are too long. The authors must rephrase them to make it all more clear and more understandable for the reader.
Please increase the size of all figures.
Please complete the Reference list with other significant references in this domain (as newest as possible) and complete the discussions and comparison with what the authors obtained and what exists now on the literature.

Reviewer 2 Report
1-What are the novelty and advantages of your method? Please clarify What exactly is the purpose of this work? Was it not possible to achieve the goals with simpler controllers? .
2- In the introduction, it is not enough to state the current work. It should be expanded and reconstructed. Including the motivation, the main work, and the improvements compared with previous related works should be emphasized in this section and explain how the present work defers from that published previously, also, the literature review given in this paper is pore to state the contribution of the present work, as there are recent works that deal with the batteries optimization which need to be added such as:
[1] Soliman, Mohamed S., et al. "Supervisory energy management of a hybrid battery/PV/tidal/wind sources integrated in DC-microgrid energy storage system." Energy Reports 7 (2021): 7728-7740.
[2] Al Alahmadi, Ahmad Aziz, et al. "Hybrid wind/PV/battery energy management-based intelligent non-integer control for smart DC-microgrid of smart university." IEEE Access 9 (2021): 98948-98961.
[3] Sahri, Younes, et al. "Energy management system for hybrid PV/wind/battery/fuel cell in microgrid-based hydrogen and economical hybrid battery/super capacitor energy storage." Energies 14.18 (2021): 5722. Etc…
3- The motivation of the research is not clear and the innovation of the paper is insufficient, if it is not then these should be respectively given.
4- The abstract and introduction is too short and a reader can't get full information of contribution. It must be revised. In particular, the last paragraph of the introduction should be seriously edited.
5-The recommended method should be presented in comparison with many other publications in the literature.

Reviewer 3 Report
I appreciate the author for considering the integrated energy system for network planning optimization. Following are the observations from the paper:-
1) In literature review section, somewhere author names are in normal and at some places (line 98,100) it is represented in all caps. Please modify.
2) Line 223, aj is mentioned as area per unit area. It is confusing, remove the confusion of readers.
I request author to please provide te answers for the following queries if possible:-
1) In the case study on optimization cost saving of 41% is mentioned. If author elaborate the cost saving it will be better for readers.
2) What will be the cost difference if independent energy analysis and integrated energy analysis is done.

Reviewer 4 Report
The manuscript systematically sorts out the process of energy network planning of integrated energy system, and proposes a bottom-up dynamic multiple load forecasting method of 8760 hours a year in China. Next comments can improve its quality:
1- Each paragraph in Introduction should has a title sentence, reasons and conclusion sentence to show the meaning and reason of writing this paragraph. In this way, the connection of paragraphs should be clear too. Refine your Introduction in the mentioned way.
2- First sentence of Line 86 is not clear. what does it mean?
3- After citing and stating each reference, explain about its shortage or difference with your research at the end of each paragraph (such as Paragraphs 3,4 and 5 of Page 2)
4- In title of Section 2 (Line14), Energy is repeated two times and it is not fluent. Modify it.
5- Add some sentences before Line 147 to explain what are these numbering telling us. What is the relationship of this lines and Figure 1?
6- Line 207, numbering started from 1 again.
7- In line 210, title of Section 2 and Section 3 are so similar. what are their difference?
8- Did you propose this methodology? Where is your references?
9- Figure 6 is not clear to see.
10- Figures 4 and 10 need legends.
11- In case study section, you need to validate your results using robustness analysis.
12- Add some policy implications in Conclusion.
Generally, I think it is a good topic and the manuscript is written fine but needs more attentions to be improved for acceptance in this journal.
