Fast Screen of Redundant Transmission Constraints in Line Contingency-Constrained Dispatch

Line contingency-constrained dispatch (LCCD) problems are challenging to solve due to the large number of transmission constraints in pre- and post-contingency scenarios, yet the majority of them are never active. This letter proposes a fast method to remove redundant constraints in LCCD problems. The linear programming problems solved in the proposed method are significantly smaller than those in the known approach.
