Intelligent Time-Adaptive Transient Stability Assessment System [PDF]
IEEE Transactions on Power Systems, 2018 Online identification of post-contingency transient stability is essential in power system control, as it facilitates the grid operator to decide and coordinate system failure correction control actions. Utilizing machine learning methods with synchrophasor measurements for transient stability assessment has received much attention recently with the ...

Truncated Transient Stability Index for On-line Power System Transient Stability Assessment [PDF]
2021 IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe), 2021 This paper assesses the ability of a Transient Stability Index (TSI) to evaluate power systems’ transient stability. The assessment is first accomplished by looking into the TSI’s classification accuracy for identifying stable or unstable cases when different transient stability thresholds are used.

Transient stability assessment using artificial neural networks
Proceedings of IEEE International Conference on Industrial Technology 2000 (IEEE Cat. No.00TH8482), 2005 Online transient stability assessment (TSA) of a power system is not yet feasible due to the intensive computation involved. Artificial neural networks (ANN) have been proposed as one of the approaches to this problem because of their ability to quickly map nonlinear relationships between the input data and the output.
