A Mathematical Model for the Scheduling of Virtual Microgrids Topology into an Active Distribution Network

Round 1

Reviewer 1 Report

The reviewer strongly recommend this work to be published after minor revision on journal.
However, some comment should pay attention to improve the quality of paper:

1. The contents and quality of paper are very good and can be understood to read. 
2. Chapter 2 should include related works and some referred work in introduction move into related works.
3. Make chapter 3 and conventional and proposed method should be described and compared in detail.
4. The list of contents are required to rearrange as follows.
     1. Introduction
     2. Related Works
     3. Proposed Method
        - conventional method
        - proposed method
        - comparison of performance
        - performance analyses
      4. Conclusion

Reviewer 2 Report

The paper developed a model-based virtual microgrid topology scheduling approach for load curtailment optimization considering demand response under the scenarios of utility grid failure.  The proposed approach is verified through simulations with four different weather scenarios.  The study is interesting, but the manuscript needs to be further improved before suitable for publication.

The language quality of the manuscript is poor due to many grammar mistakes. The language should be carefully checked and polished to enhance the readability.

Some acronyms (e.g., DG, ADN, AC-OPF) are not explained when they appear in the paper for the first time. The authors are recommended to add the description of all the acronyms in the Nomenclature section.

Line 149: The word ‘left side’ is confusing as the left side of Equation (1) is ‘Min F’.

Line 151: Suggest explaining how the value of Y can be determined.

Line 240: How is the DSR parameter (30%) selected? When applying to real systems, how can it be obtained for the optimization model development?

Line 246: Should add a short description of the reference case (MINLP).

Line 250 – 252: Suggest describing the hardware configuration of the computer used in the simulations as it affects the computation speed results.

The authors are recommended to add a discussion section to discuss how the proposed approach can be applied in real systems, highlight the importance of this research and list down the limitations.

Reviewer 3 Report

This paper needs a lot of improvements on the presentation of methodology, results and discussion.

Some recommendations and suggestions:

1. References should include some Review papers on the topic which cover the state-of-the-art. There are several such papers.
2. Introduction only mentions the voltage issues. Why frequency has been excluded?
3. Table 1: The OF error is between the MINLP and the MILP? Shouldn't the error been compared with the hypothetical scenario values?
4. Figure 4: Enlarge to be readable.
5. Section 4: Explain the 4 scenarios in more detail. Each scenario corresponds to a specific season?
6. What at the characteristics of each season, with respect to peak and average generation? Also, compare PV and Wind generation.
7. Section 4.3. You should comment on Table 2, Totals with and without DSR.
8. The significance of the tabulated results is not adequately explained.
9. The placing and sizing have been addressed in a different paper that is referenced as [12].
   It is confusing whether this research includes the placing and sizing or not. Conclusions and discussion of results does not say anything about this.
10. Language related issues 
    1. Line 73 tackles not tackle
    2. Line 73 provides not provide
    3. Line 80-83 use 3rd person
    4. Lines 86-87 the problematics of the mathematical .... not not problematic where...
    5. Lines 95-97 rewrite the question. For example: Therefore, a question that arises is.....
    6. Lines 103-105 did you mean ADN instead of AND? AND is not defined.
    7. Line 107 how much load to reduce not load reduce.
    8. Line 108 seeks not seek.
    9. Line 110 followed not follows
    10. Line 119 Consider rewriting the sentence starting with Therefore..... For example. Therefore, as shown on figure 1....
    11. Line 223-224 Confusing sentence: ....considering a connected-grid system because an autonomous network, i.e.....
    12. Line 248 both models not model
    13. Line 280 4 scenarios of 72hr each, (add the word "each")
11. References
    1. Line 432 reference 29 requires more information
    2. Line 433 reference 30 requires more information

Thank you.
