  • Sensitivity based Thevenin index for voltage stability assessment considering N-1 contingency
    Patent number: 11029344
    Abstract: Systems and method are disclosed for monitor long-term voltage stability in a power system by estimating post-contingency operating point(s) considering PV-PQ transitions based on the current operating point; predicting a sensitivity based Thevenin index (STI) for each contingency using the estimated operating condition; and determining a voltage stability assessment (VSA) considering N?1 contingency.
