摘要:In order to solve the voltage bifurcation phenomenon caused by the continuous change of the load on the UHV grid receiving end system, this paper proposes a two-stage control strategy based on the bifurcation trajectory sensitivity. Firstly, the mechanism of bifurcation of UHV receiving part's voltage is analyzed. Then the coordination correction model of voltage auxiliary decision and prediction control using bifurcation sensitivity is described. In order to verify the effect proposed, a typical accident of an ultra-high voltage receiving end is used for simulation. The simulation results show that the control effect can meet the stability requirements of the power grid, Two-stage Control Strategy could apply to solve the bifurcation problem.
