In a complex power grid, cascading failures that are triggered by some small disturbances can induce global catastrophic effects over the entire network. Based on the discussion of occurrence mechanism of power grid information physics fusion system cascading failures, this paper proposes an improved fault pattern search method. Compared with traditional search method, this method helps to improve the chain reaction set that causes the system failure, and makes it possible to make a comprehensive forecast search for grid link failures.
