•DER technology maturing, prices falling. Policies are driving DER
adoption
•In some locations, the power system is becoming dependent on the
cooperation of DERs for proper operation
•Existing issues must be addressed
•DER impacts on voltage
•Aggregate impact of DERs on bulk power system
•Protection coordination
•New issues are being identified
•Inverter response to faults
•Inverter response to load rejection events
•Inverter response to ground faults
•Inverter response to distorted voltage waveforms
•Inverter controls for grid support are maturing –many new functions are
available (and more are becoming available)
•Inverters can be designed to address many of these issues
•Standards are catching up to technology

IEEE 1547: Full Revision
Scope: This standard establishes criteria and requirements for
interconnection of distributed energy resources (DER) with electric
power systems (EPS), and associated interfaces.
Purpose: This document provides a uniform standard for the
interconnection and interoperability of distributed energy resources
(DER) with electric power systems (EPS). It provides requirements
relevant to the interconnection and interoperability performance,
operation, and testing, and, safety, maintenance and security
considerations.
Title: Draft Standard for Interconnection and Interoperability of Distributed
Energy Resources with Associated Electric Power Systems Interfaces.

Major 1547 Revision Achievements Include

•DER performance categories
o Gives flexibility to accommodate different DER futures
o Utilities/regulators need to specify which category applies (application-specific)
•More coordinated operation under normal conditions
o Many new details on reactive power capabilities and voltage/power control
requirements (not just allowance)
•Grid support under abnormal conditions
o Maintains distribution grid safety (cease to energize, trip on voltage or frequency
when necessary)
o Maintains bulk power system reliability (rides through voltage and frequency
disturbances)
•New guidance for interoperability
o Starts us on the path to more open communications
o Seeks to strike a balance between varying topologies & needs
•New guidance for intentional islands
o Much needed and immediate relevance
•Testing requirements completely revised to address new capabilities
o Strikes a balance between needs for large and small DERs

IEEE 1547.1: Full Revision
Title: Standard Conformance Test Procedures for Equipment Interconnecting
Distributed Energy Resources with Electric Power Systems and Associated
Interfaces
Scope: This standard specifies the type, production, commissioning and
periodic tests, and evaluations that shall be performed to confirm that the
interconnection and interoperation functions of equipment and systems
interconnecting distributed energy resources with the electric power system
conform to IEEE Standard 1547.
Purpose: Standardized test and evaluation procedures are necessary to
establish and verify compliance with those requirements. These test
procedures shall provide both repeatable results, independent of test location,
and flexibility to accommodate a variety of DER technologies and functions.

•What needs to be revised?
•What needs to be added?
•What needs to be external
to P1547.1?
•Goal: to come up with
P1547.1 contents that fulfill
the PAR scope and
purpose: addressing
revised requirements in
IEEE 1547
•IEEE P1547.1 provides conformance test procedures to establish and
verify compliance with the requirements of IEEE P1547
•IEEE P1547.1 is not just for type testing; conformance may be
established through combination of type (aka “design” tests), production
tests, design evaluation, installation evaluation, commissioning tests,
and periodic tests
•This standard does not cover testing for safety
•Although this standard does not define a certification process, these
P1547.1 tests can be used as part of such a process –e.g. UL 1741
•Need to keep objectives technically precise for P1547.1 –this is not a
design guide, recommended practice, business, tariff, contractual, or
regulatory and policy document

IEEE 1547.1 Revision Status
More information:
http://grouper.ieee.org/groups/scc21/1547.1_revision/1547.1_revision_index.html
P1547.1 Working Group is drafting a revision to IEEE 1547.1-2005.
•Content: Test procedures to validate conformance to IEEE P1547
•Some tests may not change substantially
•Voltage and frequency trips, synchronization
•Some tests will be updated
•Unintentional islanding, harmonics
•New tests will be added:
•Transient overvoltage (TrOV; load rejection overvoltage)
•Temporary overvoltage (TOV; ground fault overvoltage)
•Voltage regulation (volt-var, volt-watt, etc); Frequency support (frequency-watt)
•Voltage and frequency ride-through (VRT, FRT)
•Major addition:Many new DER evaluation and commissioning test procedures
•What tests/evaluations apply to a given DER depend on kVA capacity, embedded
load, and whether the DER is a single unit or includes supplemental devices
As electric grids come to depend on DERs for essential functions and services,
more thorough testing and validation are needed.
•But must balance this need with burden of testing.
