Abstract
In order to realize an efficient, safe, and reliable operation of AC/DC Hybrid Grid, in-depth research is needed in operation control and scheduling strategy. Therefore, the AC/DC Hybrid Grid voltage control and multi-source coordinated dispatching, AC/DC network mutual support and load transfer control technologies are mainly studied to support the dispatching control strategy system. In addition, constant power loads with negative impedance will cause system instability. The equivalent circuit of the AC/DC hybrid power system with a flexible interconnection device is established. Under two methods for controlling: master-slave and droop way, the impedance ratio is obtained through the equivalent circuit. Stability analysis is done by the Nyquist curve and MATLAB simulation studies for the constraint of dispatching.
