The paper analyzes the mechanisms of the individualmachine and also its advantages in TSA. Based on the criticalmachine monitoring of the original system trajectory, it is clarified that the individual-machine strictly follows the machine paradigms. These strict followings of the paradigms bring the two advantages of the individual-machine method in TSA: (i) the individual-machine trajectory stability is characterized precisely, and (ii) the individualmachine trajectory variance is depicted…

TLDR
Simulation results show that the effectiveness of the individual-machine and the equivalent machine is fully based on the strict followings of the machine paradigms, and the relationship between the machine stability and the system stability are analyzed.
Newtonian Mechanics Based Transient Stability PART III: Superimposed Machine
TLDR
This paper analyzes the mechanisms of the superimposed machine and also its inherit problems in TSA, finding that the swing and the critical stability of the system are unable to be defined strictly, and the potential energy surface cannot be modeled precisely.
Newtonian Mechanics Based Transient Stability PART V: Inner-group Machine
TLDR
This paper analyzes the mechanisms of the inner-group machine to show that the severity of the original system cannot be simply evaluated through its equivalent system once any inner- group motion becomes fierce.
Newtonian Mechanics Based Transient Stability PART VI: Machine Transformation
TLDR
Simulation results show that the machine transformation from the individual machine to the equivalent machine can be realized only through trajectory correction, and it is clarified that both energy transformation and trajectory transformation are established.

Simulation results show that the individual-machine transient energy describes the system trajectory more precisely than the superimposed global transient energy in terms of transient stability analysis, and it is demonstrated that the conjecture in early individual- machine studies might fail in special simulation cases.
