Locational Marginal Pricing and Daily Operation Scheduling of a Hydro-Thermal-Wind-Photovoltaic Power System Using BESS to Reduce Wind Power Curtailment

Round 1
Reviewer 1 Report
The authors at the beginning of the article (fig.1) present "Comparison between affluent natural energy and average wind power generation in
2019 ". Then in fig.2, they present" Average hourly capacity factor of WPPs in states of Bahia (inland) and Rio Grande do
Norte (coast), and daily profile of load demand in the Brazilian Northeast subsystem ". They do not explain how these data were averaged.
It is known that the distribution of wind energy and solar energy varies greatly throughout the year. In the case of wind energy, the authors presented this relationship in fig. 1. Unfortunately, they have not discussed this for both solar and the others they have discussed, and I believe that the lack of this information does not allow a full understanding of the problem at hand.
In my opinion, the optimization task is poorly formulated. First of all, considering only 24 hours is too much averaging. In my opinion, the changes should be considered at least daily. Otherwise, the results of the optimization process carried out are burdened with a huge error. Besides, I think that some of the conditions have been incorrectly worded. I have included the details in the comments in the article. Also, the formulation of the objective function should be rethought. Taking into account the costs of energy storage and the parameters of batteries available on the market, I believe that omitting this limitation is a big mistake.
I believe that such formulation of the optimization task is unacceptable.

Reviewer 3 Report
The proposed paper has proposed LMP formation in the DOS of the hydro-thermal-wind-photovoltaic power system with battery energy storage system and the reduction of WPC. This is an impressive and comprehensive study and the results have the potential to be published.
The authors can consider the following comments to revise the manuscript.
1. The title starts with 'LMP and Daily Operation Scheduling'. It is advised to use either abbreviations or full names for both LMP and DOS.
2. All abbreviations are not mentioned in the table.
3. Figures 6, 7, 8, 11, and 16: The blank space on the Y-axis is unnecessary. It is not mandatory to show the Y-axis values from zero.
4. Table 4, variation in generation values, i.e, MW and MWh
5. It is advised to break down Section 3 into three sections, i.e. one for the description of model and dataset, second for results, and third for Discussion/Conclusions for a better understanding to readers.

Round 2
Reviewer 1 Report
The authors' responses to my comments cleared up my doubts. All my suggestions were either taken into account or explained. I believe that the corrections introduced by the authors have increased the substantive quality of the article. I have no comments anymore.
