High Performance Computing and Security Analysis

It was shown almost fifty years ago how to apply sparsity programming techniques to power flow analysis, and several decades later ways were found to adapt those techniques to vector processing. But this kind of processing for security analysis required expensive supercomputers. Now, thanks to inexpensive processing cards spun off from those used in computerized gaming, we are on our way to being able to process large numbers of AC power flow cases on power system models and identify worrisome cases.
