Dynamic Load Management in Modern Grid Systems Using an Intelligent SDN-Based Framework
Round 1
Reviewer 1 Report
Comments and Suggestions for Authors
The article discusses the problem of using open libraries to develop a GRID system modeling platform using the SDN approach. The features of scenario formation and parameter selection are discussed. An example is given, and the modeling results are discussed.
Remarks
1. The article contains code fragments in Python, which significantly complicates its reading. It would be preferable to use a description of the algorithms, for example, in the form of flowcharts.
2. It is not entirely clear why we are talking about a framework, since open source libraries are used. It is necessary to explain this idea more clearly: why, what are the features and advantages of this approach.
3. There are no links to the libraries themselves. The text uses different terms describing the same libraries, for example, Simulink Toolbox.
4. The mathematical formulation of the problem is not neatly formatted, this also applies to the Results and Discussions section. This should definitely be corrected.
5. There are logical errors in the diagram in Figure 3.
6. The graphs in Figures 9-12 are uninformative, there is no dynamics, perhaps a tabular presentation of the data should be used.
7. In the conclusion, there is a link to source 45. It is not in the list of references.
8. The article does not present the logic of the SDN system operation.

Reviewer 2 Report
Comments and Suggestions for Authors
The work addresses real contemporary problems of electrical networks and proposes an analysis, unfortunately only simulation-based, of solution methods based on elements of modern technologies. The analysis of the current state of knowledge is exemplary, and the proposed solution in the form of topology may in the future serve as a basis for transitioning from traditional network control to distributed control.
Corrections:
1. Figs 1 and 2 need to be improved graphically; they can be much more attractive.
2. Figs 4, 6, 8 are codes and not an illustrations. As such, it can be formatted text in a box with the caption Code X, where X is the code number.
3. In figure 5, a diagram of components should be provided instead of a list.
Fig 7 the UML defines nicely methods of presenting data flow. You must learn and use UML standard.
4. The program code in table number 2 is another serious mistake in preparing the text clearly and precisely.
5. If the world is as linear and monotonic, even constant, as shown in figures 9-12, then why do the authors propose an advanced configuration of the electric grid? There seems to be a methodological error here. Of course, the analysis of the network at 1-second intervals is very appealing to me. However, when something is constant, there is no need to immediately create a graph.
6. “(1429.49,456.59,1047.59,1510.11)” , “(430.79,98.19,227.29,456.89)” please add spaces
7. Moreover, in this entire consideration, I miss, due to the temporal resolution of the analysis, the modeling of the inverters race.

Mayor comments
The main weakness of the article is the apparent lack of scientific rigor. Several statements are overly general and appear to reflect the authors' subjective opinions rather than evidence-based conclusions. For instance, the table comparing previous works lacks depth and analytical rigor. It only mentions broad aspects without providing a thorough evaluation.
The caption of Figure 4 refers to Intelligent Dynamic Load Management. However, it is unclear in what sense the approach is considered 'intelligent'. What type of intelligence is being applied? The manuscript does not provide sufficient explanation or justification for the use of this term.
The original contribution of the authors is not clearly defined. The manuscript lacks a concise explanation of how the proposed approach differs from or improves upon existing methods
Subsection 1.1 covers a topic of general knowledge that can be found in any textbook and, therefore, is not suitable for inclusion in a scientific journal
Section 1.2 should be expanded to provide additional context.
Please avoid lumping citations in the introduction section. Instead, provide key aspects of the main references.
The authors claim that their work is used 'to achieve maximum efficiency'. However, there is no evidence of actual efficiency maximization in the manuscript. Specifically, there is no optimization function provided that maximizes a mathematical expression representing network efficiency. As it stands, this statement appears to be more of a value judgment rather than a substantiated result.
Minor comments
The acronyms SDN must be defined in the abstract
The orcid of the authors is missing
The asterisk next to the name of the author indicates the correspoding author. There should be only one, not two.
In the abstract, please check the sentence “This paper uses a co-simulation framework … is designed to …”
The aesthetics of figures needs to be improved.

Comments and Suggestions for Authors
- The system proposed in Figure 2 looks strange. I know it's a simulation system, but we don't know where the data is and where the simulations are. It is also unknown where variable controlled load is mentioned. And why the load is controlled and not the number of connected loads.
- Please unify the information provided in Figures 2 and 3. Because disconnection of loads appears in Figure 3, and again there is no dynamic load change (known from some MPPT controllers).
- Drawings of "system diagrams" (diagram components) and algorithms must meet the requirements of the UML standard. The authors did not make this correction, why? the free application https://app.diagrams.net makes this process much easier.
