Anticipated accident selection method for electric power system with uncertain injection power

The invention relates to an anticipated accident selection method for an electric power system with uncertain injection power. The method comprises the following steps: (1) performing static security analysis modeling on the electric power system with uncertain bus injection power; (2) generating anticipated accident set data information; (3) simulating anticipated accidents and determining that an uncertain amount of electric power system state information is contained after the accidents; (4) determining system state interval indexes after the anticipated accidents; (5) comparing corresponding interval indexes of the accident set; (6) sequencing fault indexes and selecting an anticipated event. By adopting the static safety analysis anticipated accident selection method for the system, system running personnel can know the static safety level of the electric power system within a future period of time, and the power grid running reliability and stability are enhanced.
