Uncertainty Reduction on Flexibility Services Provision from DER by Resorting to DSO Storage Devices
Round 1
Reviewer 1 Report
Congratulations on a very interesting work. Please check the list of references - looks like one or more are missing (see the errors at lines 169, 171, 177, 181). Please also check text formatting - paragraph numbering appears twice.
Author Response
First of all, the authors wish to thank Reviewer 1 for the appreciation of the paper. In the following, the responses to Reviewer 1 comments.
Point 1: Please check the list of references - looks like one or more are missing (see the errors at lines 169, 171, 177, 181).
Response 1: These errors have been caused by the automatic procedure of conversion of the word file into pdf. They are cross-references that point to figure 1. Therefore, no references are missing in the list at the end of the paper. To avoid the occurrence of these errors again, the corresponding hypertext links have been removed.
Point 2: Please also check text formatting - paragraph numbering appears twice.
Response 2: Regarding the double numbering, again, it seems a problem in the pdf conversion from the word file. However, looking at the paragraphs' number, we noticed that we erroneously indicated at the end of the introduction only one paragraph (Section 5) for case study description and analysis of the results but in the final version of the paper, we separated these two paragraphs (5- Case Study and 6- Discussion of the results). This matching error has been corrected in the description of the paper organization (lines 117-119).
Reviewer 2 Report
The paper results interesting to read.
The discussion of a further case studio could improve the strength of the paper
There are some typo errors that should be fixed.
Abstract Any acronym should be defined at its first appearance in the paper. Anyway, the acronyms should be not used in the abstract
line 31 "Despite the COVID-19 pandemic has caused a fall in electricity consumptions" Even if this scenario could be considered true as a common sense issue, any assumption should be supported at least by a reference. Moreover "electricity consumptions" --> "electricity consumption"
line 45 the acronyms have to be defined
lines 169, 171, 177 and 181 MS Word missed the links
Is the Figure 2 useful to improve the readability and the comprehension of the paper?
Figure 4 Something of strange has occurred in the labels of the figure that are, at moment, unreadable
Figure 6 Are the load profiles coming from an analysis of true data obtained from the DSOs or they have been taken from literature?
Author Response
First of all, the authors wish to thank Reviewer 2 for the appreciation of the paper. In the following the response to Reviewer 2 comments.
Point 1: The discussion of a further case studio could improve the strength of the paper.
Response 1: The Authors agree with the reviewer that additional case studies may improve the paper strength. But they think that the more significant advance could come when the RO procedure described in the paper will be fully integrated within the planning tool. This task is under development and, hopefully, it will be ready in few months. For this reason, the Authors reckons to not add "a further case studio" within this paper because it will not bring noticeable improvement (it will be too similar to the ones already illustrated).
Point 2: There are some typo errors that should be fixed.
Abstract - Any acronym should be defined at its first appearance in the paper. Anyway, the acronyms should be not used in the abstract.
Response 2: All the acronyms have been deleted from the abstract. Their definition has been moved at their first appearance in the paper (lines 42, 46 and 53).
Point 3: line 31 - "Despite the COVID-19 pandemic has caused a fall in electricity consumptions" Even if this scenario could be considered true as a common sense issue, any assumption should be supported at least by a reference. Moreover "electricity consumptions" --> "electricity consumption"
Response 3: The typo has been corrected (line 32) and an additional reference has been added and cited in the text (line 32).

Point 4: line 45 the acronyms have to be defined
Response 4: The acronyms have been defined as requested
Point 5: lines 169, 171, 177 and 181 MS Word missed the links
Response 5: It has been an error in the automatic pdf conversion from the word file. These errors refer to the cross-reference of figure 1. To avoid the problem, the existing hypertext links have been removed from those lines.
Point 6: Is the Figure 2 useful to improve the readability and the comprehension of the paper?
Response 6: In the opinion of the Authors, Figure 2 is helpful in better highlight the over-conservatism of the general bound (6) and to stress the importance of using tighter bounds, primarily when the constraints of the RO problem are characterized by a limited number of uncertain parameters and the acceptable risk is not small.
Point 7: Figure 4 Something of strange has occurred in the labels of the figure that are, at moment, unreadable
Response 7: it is again a problem of the automatic pdf conversion that will be solved in the paper's final version.
Point 8: Figure 6 Are the load profiles coming from an analysis of true data obtained from the DSOs or they have been taken from literature?
Response 8: The load profiles have been taken from the ATLANTIDE project database, created around ten years ago for defining some reference networks finalized to the planning studies of the Italian distribution network. An additional reference has been added and cited on lines 441-442.
