Description / Abstract:
This guide describes criteria, scope, and extent for engineering
studies of the impact on area electric power systems of a
distributed resource (DR) or aggregate distributed resource
interconnected to an area electric power distribution system.
Purpose
The creation of IEEE Std 1547™-2003 has led to the increased
adoption of DR throughout distribution systems.1,2 This
document describes a methodology for performing engineering studies
of the potential impact of a DR interconnected to an area electric
power distribution system. Study scope and extent are described as
functions of identifiable characteristics of the DR, the area
electric power system, and the interconnection. Criteria are
described for determining the necessity of impact mitigation.
Establishment of this guide allows DR owners, interconnection
contractors, area electric distribution power system owners and
operators, and regulatory bodies to have a described methodology
for when distribution system impact studies are appropriate, what
data are required, how they are performed, and how the study
results are evaluated. In the absence of such guidelines, the
necessity and extent of DR interconnection impact studies has been
widely and inconsistently defined and applied.
