Abstract :
This paper presents a novel emergency damping control (EDC) to suppress inter-area oscillations occurred as anticipated low-probability cases in power system operations. The proposed EDC combines the event-driven and response-based control strategy. It is tested and evaluated in a standard power system and a real large-scale power system in China to compute the optimal location, amount and applying time of generator decreasing and load shedding in order to suppress inter-area oscillations. Test simulation results have demonstrated and validated the effectiveness of the proposed EDC scheme.
