Abstract:

A safety and stability system plays an important role in preventing the power system from large cascading failure blackouts under extreme disasters. Since the single-source data can hardly reflect the volatile weather conditions,multi-source data including the meteorological data for power grid planning are fused by spatio-temporal griding. The influence of multi-source data fusion on the security and stability verification system for power grid planning is studied, and the improvement of the proposed system on power grid's early warning is analyzed. Validated by a provincial power grid,the system extends its data collection range from the internal system to the natural environment,so as to extend early-warning objectives from single-fault risk to clustered fault risk caused by disasters. The results show that the fusion of multi-source data can effectively optimize the power network security and stability check based on single-source data,complete the unification and integration of multi-source data, improve the reliability of calculation data,and facilitate the application of power grid security and stability check.

Key words: multi-source data, security and stability, analysis and early warning, control decision, extreme disaster, power system, grid security
