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.

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. 9 IEEE 1547.1: Full Revision 10 IEEE 1547.1-2005 CONTENTS 1.Overview 2.Normative references 3.Definitions and acronyms 4.General requirements 5.Type tests 6.Production tests 7.Commissioning test 8.Periodic interconnection tests Annex A (normative) Test signals Annex B (informative) Bibliography •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 11 IEEE P1547.1: Overview IEEE P1547.1 Subgroups (as of March 2017) General requirements Overall document Abnormal voltage and frequency conditions tests Voltage and frequency regulation tests Unintentional islanding tests Power quality tests Synchronization tests Modeling and simulation Hardware-in-the- loop tests Interoperability tests Installation, commissioning, and periodic testing DER microgrid capabilities Chair: Andy Hoke Secretary: Jeannie Piekarz Treasurer: Charlie Vartanian Vice Chairs: Tim Zgonena, Babak Enayati, Karl Schoder 12 •A large number of new requirements are included in the revised IEEE 1547 –requires a number of writing groups in P1547.1 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. 13 IEEE P1547.1 new type-test content *A version exists in UL 1741 Supplement SA •Some tests may not change substantially •Voltage and frequency trips, synchronization •Some tests will be updated •Unintentional islanding*, harmonics •Many new tests will be added: •Voltage regulation (volt-var, volt-watt, etc)* •Frequency support (frequency-watt)* •Transient overvoltage (TrOV; load rejection overvoltage) •Temporary overvoltage (TOV; ground fault overvoltage) •Abnormal condition ride-through: •High/low voltage and frequency ride-through* •Consecutive disturbance ride-through* •Voltage phase angle change ride-through •Voltage imbalance ride-through •ROCOF ride-through •Soft-start tests* •Test to characterize response to voltage faults •Communications interface tests •Prioritization of response tests Tests shown in red are still to be drafted.
