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.

Generator‐based threshold for transient stability assessment
IET Smart Grid, 2019 Power systems are frequently subjected to variations of the operating conditions due to the occurrence of contingencies such as faults, load or generator tripping. These disturbances might enforce the system to enter the instability region and thus deteriorate its overall performance.

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 ...

An Optimization-Based Method for Transient Stability Assessment
2023 62nd IEEE Conference on Decision and Control (CDC), 2023 The paper proposes an optimization-based method for the transient stability assessment of lossy multi-machine power systems. To achieve this objective, a global control Lyapunov function candidate including an auxiliary state is introduced. On this basis, a new excitation control law is proposed. This control law is well-defined provided that an ‘index’

A probabilistic assessment of transient stability
International Journal of Electrical Power & Energy Systems, 1980 Abstract Transient stability assessment deals with the performance of a system when subjected to large disturbances such as faults, sudden loss of load or generation, and line switching. Most of the work carried out in this area has been based on deterministic models.

Lyapunov Functions Family Approach to Transient Stability Assessment [PDF]
IEEE Transactions on Power Systems, 2016 Analysis of transient stability of strongly nonlinear post-fault dynamics is one of the most computationally challenging parts of Dynamic Security Assessment. This paper proposes a novel approach for assessment of transient stability of the system. The approach generalizes the idea of energy methods, and extends the concept of energy function to a more

Statistical Assessment of the Impact of Renewable Energy Sources on Transient Stability [PDF]
2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2018 This paper studies the impact of penetration of Renewable Energy Sources (RES) on the dynamic behavior of large power systems. Statistical analysis of the number of instabilities and the time of occurrence of loss of synchronism in the network was performed following large number of Monte Carlo simulations and considering high degrees of uncertainty.
