Effect of DERs on the Voltage Stability of Transmission Systems using a Voltage Stability Index
… focuses on the impact on a transmission system's voltage stability. When the voltage stability at a point in the system is compromised, it can affect the entire power system's overall security, quality, and reliability. Therefore, this work aims to assess the system's stress due to increased …

Development and application of a new voltage stability index for on-line monitoring and shedding
During the past decades, voltage instability was the reason behind several major blackouts worldwide. Continuous assessment of the system voltage stability is vital to ensure a secured operation of the system. Several voltage stability indicators have been proposed and used in an attempt to …

Voltage Stability Analysis Using Simulated Synchrophasor Measurements
… under stressed conditions, which are close to instability limits. Operating power systems under such conditions along with inadequate reactive power reserves initiates a sequence of voltage instability points and can ultimately lead to a system voltage collapse. Significant research have been …

Uncertainty Modeling of Wind Power Generation for Power System Planning and Stability Study
… make it difficult to maintain power system stability and reliability. In addition, the uncertainty and variability of wind power generation (WPG) forces power utilities to retain higher levels of spinning reserves (SRs) to maintain power balance in the system. While necessary to ensure grid …

Investigation of the application of UPFC controllers for weak bus systems subjected to fault conditions. An investigation of the behaviour of a UPFC controller: the voltage stability and power transfer capability of the network and the effect of the position of unsymmetrical fault conditions.
… an investigation of static and dynamic voltage stability is presented. Two stability indices, static and dynamic, have been proposed in the thesis. Multi-Input Multi-Output (MIMO) analysis has been used for the dynamic stability analysis. Results based on the Western System Coordinate …
