The Effectiveness Function to Select Robust and Non-negatively Interactive Installing Locations and Feedback Signals of FACTS-based Stabilizers

In this paper, an effectiveness function is proposed for the selection of installing location and feedback signal of a FACTS-based stabilizer by taking account of not only its effectiveness, but also the robustness and non-negative interactions with other stabilizers. An example three-machine power system is presented in the paper to demonstrate the application of the effectiveness function proposed, where the installing location and feedback signal of a TCSC-based stabilizer is selected that not only is effective and robust, but also imposes a non-negative interaction on a PSS installed in the power system.
