Islanding defini,ons in IEEE 1547IEEE 1547 Standard for Interconnec,ng Distributed Resources with Electric Power SystemsIEEE 1547 island: a condi)on in which apor)on of an Area EPS isenergized solely by one ormore Local EPSs through theassociated PCCs while thatpor)on of the Area EPS iselectrically separated fromthe rest of the Area EPS. island, inten,onal: a plannedisland. island, uninten,onal: anunplanned island.NATIONAL RENEWABLE ENERGY LABORATORYArea EPS Utility
Uninten,onal Islanding RequirementIEEE 1547Uninten,onal Islanding For an uninten)onal island in which the DR energizes apor)on of the Area EPS through the PCC, the DRinterconnec)on system shall detect the island and cease toenergize the Area EPS within two seconds of the forma)onof an island.Inten,onal Islanding This topic is under considera)on for future revisions of thisstandard.IEEE 1547.4NATIONAL RENEWABLE ENERGY LABORATORY
Uninten,onal Island Detec,on MethodsIEEE 1547Some examples by which this requirement may be met are:1. The DR aggregate capacity is less than one‐third of theminimum load of the Local EPS.2. The DR is cer)fied to pass an applicable non‐islanding test.3. The DR installa)on contains reverse or minimum power flowprotec)on, sensed between the Point of DR Connec)on andthe PCC, which will disconnect or isolate the DR if power flowfrom the Area EPS to the Local EPS reverses or falls below aset threshold.4. The DR contains other non‐islanding means such as a) forcedfrequency or voltage shiOing, b) transfer trip, or c) governorand excita)on controls that maintain constant power andconstant power factor.NATIONAL RENEWABLE ENERGY LABORATORY

IEEE 1547.4 InformationIEEE 1547.4 provides alternative approaches and good practices for thedesign, operation, and integration of distributed resource (DR) islandsystems with electric power systems (EPS). This includes the ability toseparate from and reconnect to part of the area EPS while providingpower to the islanded local EPSs. This guide includes the distributedresources, interconnection systems, and participating electric powersystems.Chair: Ben Kroposki, Secretary: Tom BassoPAR started:1st Ballot (Draft 10):2nd Ballot (Draft 11):3rd Ballot (Draft 12):Expected Pub Date:2005March 2010, 250 people on ballot groupover 400 comments, 88% affirmativeMarch 2011, 25 comments, 91% affirmativeMay 2011, comments, % approvalJune 2011NATIONAL RENEWABLE ENERGY LABORATORY
IEEE 1547.4 InformationDue to some of the confusion surrounding the definition of microgrid in2005 (and continues today), IEEE 1547.4 developed the termDistributed Resource Island System.The term “DR island systems”, sometimes referred to as microgrids, isused for electric power systems that:1. have DR and load2. have the ability to disconnect from and parallel with the area EPS3. include the local EPS and may include portions of the area EPS,and4. are intentionally planned.DR island systems can be either local EPS islands or area EPS islands.NATIONAL RENEWABLE ENERGY LABORATORY

Clause 4 – DR Island System Overview4.2 Specific considerations for DR island systemsthat include a portion of the area EPS There is an agreement with the area EPS operator to operate the DR islandsystem. The participating and non-participating DR need to be identified. During transition to and operation of the planned island, one or more of theparticipating DR may be allowed to operate according to a predefined set ofrequirements outside of IEEE Std 1547-2008. The area EPS is modified to operate in the planned island mode. It may be necessary to conduct load flow and stability studies to identify anyrisks that operation of the nonparticipating DR may be compromised or maycompromise the DR island system. The planned DR island system should maintain voltage and frequency for theentire island system including the non-participating DR systems and loads.NATIONAL RENEWABLE ENERGY LABORATORY
