This guide describes a methodology for determining when it is necessary to conduct engineering studies to evaluate the potential impact of a Distributed Energy Resource (DER) interconnected to an Area Electric Power System (Area EPS). The guide also identifies the scope and extent of such studies as functions of identifiable characteristics of the distributed energy resource, the Area EPS, and the interconnection. The guide further addresses studies of the impacts of aggregated DER on an Area EPS and describes criteria for determining mitigation. The guide provides information on five types of studies: (1) Screening assessment – simple yes or no tests for interconnections (2) Steady-state studies – electrical studies that look at the steady state operation of the interconnection and surrounding EPS facilities (3) Transient and dynamic studies – including power quality issues such as harmonics, voltage, flicker, and other stability issues (4) Impacts on Area EPS protection, communications, and control (5) Other studies – studies that do not fall into the first 4 categories. Based on the screens and results of studies, the guide recommends additional studies or steps to be completed.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.

IEEE Guide for Conducting Distribution Impact Studies for Distributed Resource Interconnection
IEEE Std 1547.7™ is part of the IEEE 1547™ series of standards. Whereas IEEE Std 1547™-2003 provides mandatory requirements for the interconnection of distributed resources (DR) with electric power systems (EPS), this guide does not presume the interconnection is IEEE 1547™ compliant. Further, this guide does not interpret IEEE Std 1547™ or other standards in the IEEE 1547™ series, and this guide does not provide additional requirements or recommended practices related to the other IEEE 1547™ documents. However, DR interconnection may contribute to resultant conditions that could exceed what was normally planned for and built into the distribution system. This guide provides alternative approaches and good practices for engineering studies of the potential impacts of a DR or aggregate DR interconnected to the electric power distribution system. This guide describes criteria, scope, and extent for those engineering studies. Study scope and extent are described as functions of identifiable characteristics of the DR, the EPS, and the interconnection. The intent includes promoting impact study consistency while helping identify only those studies that should be performed based on technically transparent criteria for the DR interconnection.
