Abstract

VSC HVDC has a wide application prospect and it has many merits in contrast to conventional HVDC. The models of AC/DC hybrid power system with VSC HVDC are established in this paper. Utilizing the fast power flow adjustment ability of VSC HVDC, a novel control strategy stabilizing AC and DC system synthetically is proposed. A performance index, which is composed of generator and AC system variables, is formed for the optimization of controller parameters by using genetic algorithm (GA). The simulation results illustrate that with the proposed control strategy, the AC and DC system can recover rapidly from a large disturbance; furthermore, they have no negative influence on each other
