| description | The invention relates to a power grid cascading failure risk quantitative assessment method, device and equipment, and belongs to the technical field of power system risk assessment. The device comprises a grid structure, a target power grid power supply structure and target power grid overall power flow distribution information; based on a preset model and the risk factor data, determining the occurrence probability of each risk factor and the level of consequences generated after the cascading failure occurs; according to the occurrence probability of each risk factor and the grade of consequences generated after the cascading failure occurs, the risk of the cascading failure of the target power grid is quantitatively assessed, so that the risk of the cascading failure of the power grid is assessed, early warning is performed, loss is reduced, and the problem urgently needs to be solved in the prior art.
