Power system cascading failure modeling method, device and equipment and readable storage medium

The invention provides an electric power system cascading failure modeling method, device and equipment and a readable storage medium, the method provided by the invention can perform modeling simulation on complex key elements in a complex electric power system, not only can accurately reflect power grid cascading failure characteristics, but also can ensure high operation efficiency, and can improve the power grid cascading failure modeling efficiency. Therefore, research and analysis of the cascading failure of the power grid are more efficient and accurate, the simulation efficiency of the cascading failure of the power system is greatly improved while dynamic characteristics of the cascading failure of the power system are not excessively lost, simulation and analysis of the cascading failure of the power system become more efficient, and the method is suitable for popularization and application. And technical support is provided for safety risk identification and safe and stable operation of the power g
