An oscillation transient energy function (OTEF) is proposed for the analysis and damping of power system area-mode oscillations. The OTEF interprets an area-mode oscillation as the conversion between oscillation kinetic energy and potential energy. Based on this interpretation, an OTEF descent method has been developed to design a supplementary fuzzy-logic thyristor controlled series compensator (TCSC) controller to damp the area-mode oscillation. Since the proposed method guarantees the continuous descent of oscillation energy, the fuzzy-logic TCSC damping controller designed is robust to the variations of power system operating conditions. A 4-generator 2-area interconnected power system is presented to demonstrate the effectiveness and robustness of the TCSC fuzzy logic damping controller installed in the power system.
