Abstract :
A set of algorithms for security-constrained optimal power flow (SCOPF) and their configuration in an integrated package for real-time security enhancement is described. The emphasis is on the discussion of the SCOPF algorithms and the insights gained from their implementation. The security problem is identified, and the security enhancement system configuration implemented to address this problem is described. Insights into the separation of recommendations to obtain feasibility (no base case violations or unmanageable contingency violations) and recommendations to approach the optimal (least cost feasible) operating point are presented. An introduction of nonconvex SCOPF methods for modeling utility operating policy is given. Interfaces from the SCOPF functions are discussed. The results in terms of current status and initial use of the operational system are briefly summarized
