Abstract
Transient stability analysis plays a crucial role in upholding the robustness and dependability of power systems when confronted with sudden disruptions. This study introduces a thorough transient stability test specifically crafted to appraise a power system's capacity to sustain synchronism and stability in the aftermath of unforeseen incidents, such as faults or rapid load fluctuations. The analysis employs intricate mathematical models to replicate the dynamic responses of generators, transmission lines, and other components during and post disturbances. A pivotal parameter evaluated in this study is the critical clearing time, indicative of the maximum duration of a disturbance before stability becomes compromised. The Energy Functions Method (EFM) is harnessed to monitor the energy exchange within the system, offering valuable insights into stability margins. Furthermore, contingency analysis is executed to pinpoint potential vulnerabilities and augment the overall resilience of the system. To facilitate prompt decision-making by power system operators, real-time applications are integrated into the test. Ongoing research endeavors are directed towards advancing computational techniques, encompassing machine learning and data-driven approaches, to enhance the precision and efficiency of transient stability assessments. This transient stability test contributes significantly to the persistent endeavors aimed at ensuring the secure operation of power systems.
