Cascading Fault Analysis in Cyber–Physical Power Systems Containing Wind Generator Considering Routing Strategy

The data transmission efficiency of information network has a great impact on the cascade failure of cyberphysical power systems, and this paper proposes a dynamic information network transmission path selection method to improve the data transmission efficiency of information network during cascade failure. At the same time, due to the large number of distributed wind power connected to the grid, the uncertainty of its output may aggravate the degree of cascade failure, and this paper proposes an energy storage output model to suppress the uncertainty of wind power output. Meanwhile, a dynamic tidal algorithm is used in the tidal current calculation. Finally, experiments are conducted in the IEEE39 node system, and the simulation results show that the proposed method can effectively mitigate power system cascading faults.
