Abstract
With the rapid development of new energy generation, the influence of large-scale wind/solar hybrid system on power system transient voltage stability cannot be ignored. First, large-scale wind/solar hybrid system model is established based on simulation software Power Factory/DIgSILENT in this paper. An advanced control strategy for hybrid model by adding a damping controller in the rotor side of DFIG is proposed. This strategy could improve the fault ride through capability of wind turbines effectively. Second, the effect of large-scale wind/solar hybrid system on transient voltage stability is analyzed in different operation modes. The analysis results show that the effect of wind/solar hybrid system mode on system voltage oscillation is the lowest compared with the wind turbines operating separately mode and PV panels operating separately mode. The stability and safety of the power grid based on the hybrid system are improved. Finally, the efficiency and accuracy of the proposed control scheme are validated by simulation software Power Factory/DIgSILENT.
