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.

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’
