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