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.
