The Coordinated Control Strategies of Voltage Stability Based on Expert Rules

According to the process characteristics and control methods of different voltage stability problems, the paper researches control rules and strategies of the voltage stability, then sets up controllers of FACTS devices on a simulation platform, and puts forward the coordinated control strategies of voltage stability problems based on expert rules. The simulation studies have shown that control effects of multiple FACTS devices are significantly better than a single device, and the coordinated control methods based on the expert rules is more conducive to improving voltage stability.
