Extreme weather events such as typhoons pose a serious threat to the safe operation of power grids. In field system resilience assessment during typhoon disasters, parametric wind model combined with actual historical meteorological data has not been well adopted, and conventional renewable energy uncertainty modeling methods are suitable for disaster periods. this paper, multi-indicator fused strategy considering wind-photovoltaic component failure disasters is proposed. Firstly, based on typhoons, an speed established by rolling non-parametric Dirichlet process Gaussian mixture model. Then, spatial–temporal contingency set constructed best-fit stress–strength interference probability transmission lines. On basis, holistic framework from perspectives priority, robustness, rapidity, sustainability, entropy weight method technology order preference similarity ideal solution leveraged obtain comprehensive indicator. Finally, numerical studies performed IEEE-30 bus test identify vulnerable lines improve disasters.
