Energy Science &Engineering, Volume 13, Issue 6, Page 2720-2756, June 2025.Series and Shunt Reactive compensation can be used to improve voltage stability. The L‐index and Fast Voltage Stability Index are used to evaluate stability. Cost of reactive compensation is included directly in the optimization process. Multi‐objective optimization determines the optimal sizing of FACTS devices.
