Abstract
This paper studies the severity of cascading failure processes of electrical power grids by statistically analyzing the number of line outages per cascade, the cascade duration, and the load shedding amount of a cascade, based on the historical utility data of the BPA system and the simulation data of two synthetic test cases. Both uniform and non-uniform probability distribution functions have been considered for the initial line trips in the cascading failure simulation in order to determine which function better approximates the cascading failure risks of the real-world grid. The obtained simulation data and statistical analysis results from the two 500-bus synthetic test cases are then compared with those from the historical utility data.
