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.
