Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The paper is worthy for publication in the control domain. Issues must be solved...

Is it possible to implement it through MATLAB?

How are the plots generated?

RT-box hardware in loop etc, more validation is needed.

Acronym abbreviation is needed

More details about table 1 and 2

Is it possible to implement it through MATLAB?

How are the plots generated?

RT-box hardware in loop etc, more validation is needed.

The authors presented some plots (control theory). I suppose that they can derive them using MATLAB.


No discussion about hpow are the plots generated?

What does mean RT-box hardware in loop ?


Also, it is not adequate to simply mention the tables.

The theory has a good presentation. But, it is needed more validation according to the above

Reviewer 3 Report

Comments and Suggestions for Authors

This paper proposes a power decoupling control strategy utilizing a reduced-order ESO to enhance the robustness of the GFM power decoupling control strategy against perturbations in line impedance parameters. 

The approach takes into account various factors influencing power control performance, including model deviations and power coupling resulting from perturbations in line impedance parameters, treating them as internal disturbances. 

Utilizing the conventional power control strategy and virtual impedance method as a basis, the reduced-order ESO actively monitors and compensates for these disturbances in real-time.

The results of the publication have a significant contribution to the connecting new energy sources to the network.

The article has a good scientific quality and is free from obvious errors, is clear, concise, and well organized.

Comments and suggestions:

1) In figures 8 to 15, the labeling of the axes, the values of the quantities and the legend are missing

2) How can the negative value of the virtual resistors (-3 Ohm) in Table 1 and 2 be explained physically?
