1. Overview of Framework for Tools to Archive and Analyze Real Time Grid Data Carlos Martinez January 27-29, 2004 Washington, D.C. Transmission Reliability Research Review

2. Goals Vision/Goal: Define and report the framework and constraints to be addressed in developing tools to archive and analyze real-time grid data. The value of such a system would be better utilization of available data to improve reliability management, market monitoring and, ultimately, improved market efficiency. Key Issues being addressed:  Real time monitoring applications data requirements will be reviewed  Framework for data and information archiving systems will be researched to lay a foundation for effective and systematic data and information management for real-time monitoring of power systems  Data quality requirements will be identified and processes to improve data quality will be identified and reported.
