Applications of DER Advanced Functions and Settings Devin Van Zandt, EPRI June 26, 2019 ITWG Meeting w w w . e p r i . c o 2019 Electric Power Research Institute, Inc. All rights reserved. m Quick Snapshot IEEE 1547-2018 applies to ALL DER, not just inverters Solar PV is dominating in most regions, but standard applies to all Some IEEE-1547 requirements will be difficult for synchronous machines to meet

CA R21 and Hawaii R14 Inverters are available today and could be used IEEE 1547-2018 DER tested to 1547.1 will be available late 2021/early 2022 IEEE 1547-2018 ride-through capabilities are very important for bulk system as penetration levels increase EPRI has been very involved in both T&D impacts of DER and advanced functions 2 ww w.epri.co m 2019 Electric Power Research Institute, Inc.
