Fast Power System Transient Stability Simulation
Round 1
Reviewer 1 Report
The paper provides a clear and concise overview of the concept of fast power system transient stability simulation. It effectively introduces the importance of transient stability analysis in maintaining the reliability of electrical power systems. The paper appropriately emphasizes the importance of accurate mathematical models of power system components for fast transient stability simulations.
1. The paper discusses numerical integration techniques, which are central to fast transient stability simulations. However, more information on the specific simulation algorithms employed and their advantages could enhance the paper's technical rigor.
2. Consider discussing the practical implications and limitations of implementing the proposed technique in real-world power system operations. Address issues related to data availability, model complexity, and potential challenges in applying the method to different grid configurations.
3. Please proofread for grammatical mistakes
4. Please follow the journal format for all references for example Reg 13, 22 and 23
Ensure to proofread the paper for better English quality.

Reviewer 2 Report
Solving a DAE system with an adaptive length of time intervals has been intensively studied in the past several decades. A vast amount of papers have been published both in theoretical analysis and applications. Authors of this paper should
1) provide a detailed review of previous studies;
2) discuss your reasons why you choose this method;
3) give a theoretical analysis about the stability of the discrte system;
4) convergence properties of using the proposed approach;
5) compare results by using different methods for evaluating the errors due to the discretization.
English is acceptable.

Reviewer 3 Report
1. The introduction does not provide enough background and lacks sufficient relevant references. It needs improvement.
2. It is suggested to provide topology diagrams for the IEEE 9-bus system
and the IEEE 39-bus system, clearly indicating the three-phase short circuit fault.
3.The section about determining the new step size lacks sufficient explanation of the theoretical basis and lacks logical coherence.
4.The example section does not sufficiently explain the adaptive step size differential transformation method and fails to demonstrate the superiority of the proposed method in simulating the transient stability of power systems.

Round 2
Reviewer 2 Report
Although the authors modified the manuscript and responded the comments of the reviewer, the expressions in the mathematical equations are surprisingly poor. For example, there are unacceptable mistakes in Eq. (1) and (2). Consequently, the reviewer cannot go further through the derivations.
Besides the mathematical mistakes, there are many typos in the text.
Author Response
Dear Sir
thank you for your building comments. accordingly I have edited the following parts
- Background introductory part
- little grammatical errors in different parts of the main text are corrected
- Correction on Equation 1 and 2
- Some of the equations are rewritten again
- More describing information’s are added for different equations
with great respect
