摘要：
In order to solve the problems of coordinated control and voltage stability of SES-VSC-MTDC(Self-Energy Storage based Multi-Terminal back-to-back VSC-HVDC) system,an improved voltage margin control strategy is proposed. Firstly,the system mathematical model is established,and then the coordinated working mechanism and its control mode are designed for three typical operation scenarios. Based on the Lyapunov stability theory,an adaptive command-filtered backstepping voltage controller is designed to solve the pro-blems of power oscillation and voltage fluctuation caused by the switching of system control mode,which improves the stability and dynamic response of the system. Finally,the simulation analysis of three typical ope-ration scenarios is carried out to verify the effectiveness of the proposed control strategy and method. © 2019, Electric Power Automation Equipment Press.
