Abstract :
Dynamic reactive power reserve of power system is vital to improve transient voltage security. A novel definition of reactive power reserve considering transient voltage security in transient procession is proposed. Participation factor to evaluate reactive power reserve´s contribution to transient voltage stability is computed through trajectory sensitivity method. Then an optimization model to enhance transient voltage stability is built and a solving algorithm is proposed. Based on an analysis of the transient voltage stability characteristics of East China Power Grid, the effectiveness of the proposed dynamical reactive power reserve optimization approach for improving transient voltage stability of large-scale AC-DC hybrid power systems is verified.
