A Robust Control for TCSC Based on a Multiple Model Adaptive Control Strategy

Linear TCSC damping controller is bad in adaptability and robustness, but its control strategy is simple and easy to be implemented; on the contrary, the nonlinear TCSC damping controller has the better adaptability and robustness, but its control strategy is too complicated. A multiple model adaptive control strategy for robust damping of interarea oscillation in power system is put forward in this thesis. Based on the recursive Bayes theorem, the weight for each model is calculated and final output of the controller is synthesized by the weights. A more satisfied performance in adaptive and robust for the new model is proofed by the simulation result.
