Abstract
The dynamic response of ultra-high voltage direct current (UHVDC) will significantly affect AC/DC power grids. Accurate simulation for control systems of UHVDC lays a solid foundation for bulk power systems stability analysis. Based on the latest UHVDC models with real control systems in PSD-BPA, this paper investigates dynamic behavior of UHVDC when AC voltage of the rectifier side oscillates quickly. The mechanism of AC overvoltage phenomenon caused by reactive power surplus is clearly explained. Impact factor analysis for AC voltage and control parameters is carried out. Optimization measures for UHVDC control parameters are proposed. Study cases for real UHVDC projects in northwest power grids verify that the proposed optimization measures can improve the dynamic response characteristics of UHVDC and mitigate the risk of wind generation tripping-off.
