IEEE P1729

Revision Standard - Active - Draft.
This recommended practice aims to expand the use of IEEE power distribution test 6 feeders into a broader space of software developers, software users, and researchers. The need for new distribution software functionality evolves quickly in areas such as distributed resource modeling, load response to voltage and frequency, reliability improvement, neutral-earth voltage, active controls, interoperability, etc. By leveraging and expanding the set of test feeders, more attention can focus on providing the new functionality. The scope of the recommended practice includes steady-state, event-based, probabilistic, stochastic, and dynamic analysis of electric utility power distribution systems. Industrial and commercial power distribution systems, harmonic analysis, and electromagnetic transient analysis are all excluded.

This document defines recommendations for steady-state, event-based, probabilistic, stochastic, and dynamic analysis of electric utility power distribution systems. Industrial and commercial power distribution systems, harmonic analysis, and electromagnetic transient analysis are all excluded.
Many commercial software products and academic research projects continue to use analysis methods appropriate for transmission systems, but not for distribution systems. Many research papers submitted for publication still address questions that have been well-settled by previous work. The purpose of this Recommended Practice is to focus research attention on areas where legitimate needs exist, to identify methods that should not be used in software products, and to provide guidance on the application of new analysis methods to electric utility distribution systems.
