An Algorithm for Real-Time Security Constrained Economic Dispatch

The paper presents results from the development and testing of an algorithm for security constrained dispatch calculations wherein closed-area MW, line MW and MVA, and line-group MW constraints must be considered to insure system security. An overview of the algorithm and partial results from full-scale benchmark tests using a real-time 1200-bus/1500-line model and an optimal power flow (OPF) are presented in the body of the paper. Several appendices are included to outline the techniques used in the algorithm development.
