Abstract :
In virtue the polytopic system theory, the present study proposes a wide-area robust decentralized coordinated controller that stabilizes the system and enhances the system robustness simultaneously under different operating conditions. Based on the design algorithm, the closed-loop control system can be operated under strong damping mode in virtue of the stability criterion based on damping ratio. A wide-area robust decentralized coordinated control framework for HVDC power system is then put forward, where the upper level wide-area coordinated controller is designed as a dynamic output feedback controller that coordinates the lower level HVDC supplementary controller, PSS and SVC. Simulation results have demonstrated the effectiveness and applicability of the proposed controller.
