Distribution Systems Testing, Application, and Research (DSTAR) is a consortium of electric distribution utilities and utility organizations that collaboratively sponsor near-term, pragmatic distribution research and development.
Similar to the DEED program, DSTAR leverages funding for innovative electric industry research and development in today’s competitive utility environment. All research activities are envisioned and directed by DSTAR member utilities. Research typically includes equipment testing and product evaluation, niche software for standards and engineering support, and whitepapers and reports on pressing industry issues.
Listen to an informational webinar about DSTAR.
DEED joined DSTAR in 2010. As a result of its membership, all Association members may access current DSTAR research. DSTAR bundles multiple research projects into a “program” that typically lasts about 1.5 -2 years. Association members may access DSTAR’s program 13, 14, and 15 research projects. A few older, valuable projects have also been given to DEED for the benefit of Association members and are noted below.
DSTAR periodically publishes a newsletter to provide an overview of the DSTAR program and research being conducted. View prior issues.

DSTAR Distribution e-handbook
Distribution engineers and technicians frequently use one or more "paper" handbooks to find vital engineering information or refer to tables in these handbooks to obtain simple calculated values. The goal of the DSTAR Data e-Handbook is to create a dynamic electronic document that consists of information commonly used by electric utility engineering and operations personnel. Covering a variety of distribution engineering topics, the DSTAR e-Handbook is intended to be an authoritative source of information. The material included in the e-Handbook has been obtained from existing distribution handbooks, manufacturer information, standards documents, results from DSTAR software programs, and surveys of the DSTAR membership.

Secondary Electrical Design Software (SEDS)
The Secondary Electrical Design Software (SEDS), has been successfully used by the DSTAR membership to perform electrical calculations, such as voltage drop and flicker, for multi-tiered, single-phase and three-phase secondary systems. SEDS employs a drag and drop-style user interface that is very simple to use and affords users tremendous flexibility. Improvements to the three-phase load database, some GUI enhancements, bulk editing importing of data, and the handling of seasonal coincidence factors were added in 2012.
Distributed Generation Impact on Distribution Systems, Project 8-8
This project resulted in a white paper report which describes the various distributed generation technologies and summarizes their impact on distribution system design, operation, and protection. The evaluation includes the following topics: Characteristics of "distributed resources" technologies; Why and where DR are or might be applied; How they may affect distribution system performance; Impact on system reliability; Current interconnection standards activities; How DR Impacts can be minimized; Future concepts where DR can be used to help the distribution system. View the final report.
Best Practices for Storm Response on U.S. Distribution Systems, Project 11-7
This report examines the practices, procedures and experiences of U.S. utilities during major storm occurrences with the goal of understanding and conveying what went right and what went wrong during the build-up, restoration and ramp-down phases. View the slides from the September 17, 2013 webinar.
Association members (login required) may access Program 13, 14, and 15 research which includes the following projects.
