Wind power has become one of the renewable energy sources with mature technology, economic feasibility and wide application in the world, however, wind farms in our country are at the end of the regional power grid, so their power grid structure and safety and stability are relatively weak. Wind farm accident is likely to bring high wind power penetration, and it may even change the power flow distribution of the regional power grid in which the accident happens, which threatens the static and transient stability of the whole power grid. Research is made on the power system with wind farm, and according to the impact of wind farm on the vulnerability of grid operation state, method of forecasting power grid cascading failures under the condition of wind farm integration is proposed. Wind power grid-connected capacity and ways of grid-connection of wind farm and the impact of wind farm accident upon power grid cascading failures are studied. Simulation analysis of IEEE-57 bus system verifies the rationality, feasibility and validity of the proposed forecasting method.
