Evaluation of Voltage Stability Assessment Methodologies in Transmission Systems

Voltage stability refers to the ability of any electrical power system to ensure acceptable voltage performance at all buses whenever a disturbance occurs. In this webinar, the definitions of voltage stability have been revisited and further illustrated in relation to distributed energy resources and power electronics interfaced devices. Several reports on voltage stability have been published in recent decades by CIGRE and IEEE, such as CIGRE Technical Brochures 91, 128, 231, and 504, and IEEE Technical Report 90TH0358-2, and a more recent one on the contribution of distributed energy resources to system stability (IEEE Technical Report PES-TR22). These valuable references cover the fundamentals of available indices, analysis methods, and industry experience in voltage stability…
