Nonlinear Transient Stability Analysis of Phased-Locked Loop-Based Grid-Following Voltage-Source Converters Using Lyapunov’s Direct Method

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021
In this article, using Lyapunov’s stability theorem, the transient stability conditions for a grid-following voltage-source converter (VSC) are found. These conditions take into account both the grid specifications and the VSC’s dynamics.

Transient Stability Sensitivity Analysis

Electric Power Components and Systems, 2004
Based on the time domain simulation, the sensitivity of stability margin with respect to node active and reactive power for the system is derived. They can be used in the location selection of transient stability control devices, stability margin constraint of security based economic dispatch and online stability monitoring.

Transient Stability Program Output Analysis

IEEE Transactions on Power Systems, 1986
The output of a conventional transient stability program is analyzed using transient energy functions for individual machines. The analyst is provided with a quantitative index of the degree of stability or instability for each generator. This index is useful for guiding the selection of subsequent case studies.

Transient stability analysis using diakoptics

IEE-IERE Proceedings - India, 1978
The method of diakoptics is applied to the transient stability analysis of a power system. Diakoptics is used to obtain the transmission line power flows that are required in the step-by-step method. Through this approach, the stability studies of large power systems could be studied.
