Common principles

Original configurations remain the starting point. Modified variants and alternative values are separately labeled by source and publication year. Each system page has its own data, figures, model files, results and bibliography; incomplete entries are clearly identified.

Research release — verification required. Care has been taken to match the published IEEE test-system descriptions. Users MUST check data, equipment connectivity, operating assumptions and results against the cited source before relying on any file. Report omissions, revisions and discrepancies to sagarwal@gri-us.com. Revisions will be reviewed, attributed and versioned. Only available native file formats are provided.

Contribute a model or correction

Researchers are welcome to submit previously published data, alternative configurations, correction notices or verified study results. Email sagarwal@gri-us.com; an integrated GR-domain upload facility is being prepared. Research contributions are reviewed before publication.
