Power system model data provenance

Abstract

A model of a power system is a representation of that system. The value of that model depends on both the degree to which the model correctly represents the power system, and the analyses for which that model will be used. The documentation of the data used in a model is the provenance of that data. This paper discusses the provenance of data which appears in a power system model. While model data provenance is important for any model, data provenance is especially important when a model is to be maintained and used repeatedly for the life of a facility.
