Insightful Electric Vehicle Utility Grid Aggregator Methodology Based on the G2V and V2G Technologies in Egypt
Round 1
Reviewer 1 Report
1. The Eq. (2) is a normalized equation and hence K1 and K2 are not compatible to subtract from each other. Hence the authors need to modify the Equations 2, 3, 4.
2. The convergence plot obtained with GA for the objective function has to be provided.
3. A neat flow chart diagram for the proposed algorithm is need to be provided.
4. In Table-2 in the second time slot the no of EVs are quite large compared to time slot one. How the number of EVs per slot are considered.
5. The total degradation costs projected are seems to be not realistic. Please verify them.

Reviewer 2 Report
In this paper, a novel and robust central insightful aggregator hierarchical optimization algorithm based on the genetic algorithm (GA) is implemented and investigated. The 203 proposed model has minimized the battery degradation cost and maximized the EV owner profit by selecting the number of EVs that would participate in the V2G and G2V technologies to shave the load demand of the grid. The subject is timely and interesting. However, after careful reviewing of the paper the following comments need to be taken into consideration:
1- Literature review should be improved. A taxonomy table should be included to compare the features of the paper in comparison to the other previous works.
2- Why did the authors use GA? Why mathematical oriented methods can not be applicable?
3- Following by comment 2, I suggest the authors to compare the performance of the GA with the other heuristic algorithms.
4- A nomenclature should be included.
5- What is the exact and practical conclusion of the paper? I can not understand it. What does the paper bring for the policy maker and/or operators?
6- I think the model and the method should be stated separately. In 2.3, they have been mixed. Before stating the objective function, a sentence about GA is stated. It would be confusing.
I hope my comments help the authors to improve their work.

Reviewer 3 Report
Dear authors,
This paper is a great work, I have a few suggestions for enhancing the overall view of the paper. These are the following:
· I kindly suggest you avoid the informal use of the English in the Abstract and the rest of the paper.
· Equations 2,4,5 please avoid using the “*” rather than “·”, it looks more formal
· Table 2, Table 3 lacks the units, please add it.
· In section 2, I miss a subsection where the important key factor is highlighted, for example: maximum DoD (allowed for this experimentation), how the aggregation is made for this paper, definition like V2G slight differ from G2V as consequence this should be exposed here, why choosing these brands and model of cars, and not others, etc.
· I highly recommend read the following paper (10.3390/buildings12030264) and consider the paper as this is a new publication which is closely related to the focus of this research.
