Excessive carbon emissions leading to global climate deterioration pose a severe threat to the stable operation of power systems. Hybrid simulations have been used to uncover the influence mechanism and dynamic interaction process between extreme weather conditions and power systems, with models constructed to establish the relationship between meteorological conditions and grid failure.
Global climate deterioration caused by excessive carbon emissions poses a severe threat to the stable operation of power systems. In extreme snow and ice weather, complex faults, such as ice-covered line breakage and insulator flashover, may be triggered. Hybrid simulations to reveal the influence mechanism and dynamic interaction process between extreme weather and power systems have become a research focus. Relationship models between meteorological conditions and grid failure were constructed in ice accretion and insulator flashover scenarios. Based on the above two models, a multi-variable and multi-time scale hybrid simulation of the meteorological process and power system, considering line icing and insulator flashover, was realized. An example was provided to verify the feasibility of the proposed simulation scheme.
