Update on PJM Stakeholder Efforts for Ride-Through of DER and IEEE 1547 -2018 MADRI meeting #53 July 18, 2019 Andrew Levitt, Senior Business Solution Architect, Applied Innovation www. pjm. com PJM© 2019

Why Care About IEEE 1547 -2018? IEEE standard 1547 facilitates DER interconnection. • Takeaway 1: old IEEE 1547 -2003 is retiring, is in laws & regs of most states. • PJM has long-term reliability concerns with old IEEE 1547 -2003. – No immediate concerns, and no anticipated need for retrofits. • New IEEE 1547 -2018 is a “smart inverter” standard. • Manufacturers moving away from IEEE 1547 -2003 and towards “smart inverters” (e. g. , CA, HI, MA). Starting in early 2020 s, DER equipment will increasingly be designed for IEEE 1547 -2018 and not old IEEE 1547 -2003. www. pjm. com 4 PJM© 2019

Cumulative Non-wholesale Solar MW More DER deployment in PJM Ride Through for DER • “Ride Through”: resource remains connected for a short time during/after transmission fault. • Required for big generators. • Takeaway 2: reliable integration of more DER in PJM ride through should be required for DER, too. www. pjm. com 5 PJM© 2019

Takeaway 3: IEEE 1547 -2018 More Policy Engagement Old IEEE 1547 -2003 New IEEE 1547 -2018 Take it or leave it. Pick a flavor. “The small generator shall be listed to meet the requirements of IEEE 15472003”. “The small generator shall be listed to meet the requirements of IEEE 15472018 using normal operating performance Category A and abnormal operation performance Category II, with the UV 1 trip point adjusted to [Y] seconds and the UV 2 trip point adjusted to [X] seconds. ” Examples of state stakeholder working groups on ride through and trip settings : Maryland PC-44 Phase II Interconnection Working Group, Massachusetts Technical Standards Review Group, Minnesota Distributed Generation Workgroup Technical Subgroup, CA Smart Inverter Working Group www. pjm. com 7 PJM© 2019

PJM Stakeholder Effort for DER Ride Through Q 1 2018: Preliminary trial workshop w/ 4 utilities (T and D) Q 4 2018: Approved DER Ride Through Task Force Charter for PJM to work with distribution utilities, DER developers, et al to develop recommendations on ride through and trip settings Q 1 2019: Launch DERRTTF ~monthly meetings. Q 4 2019: Deliverables Takeaway 4: PJM Ride Through PJM Rules www. pjm. com Guidance Document for States 9 PJM© 2019

Takeaways 1. Old IEEE 1547 -2003 is in state laws/regs, has been revised to more complex IEEE 1547 -2018 standard for “smart inverters”. 2. PJM has a narrow interest in the “ride through” and trip portion of the IEEE 1547 -2018 standard. 3. IEEE standard 1547 -2018 requires more policy engagement than the prior edition of the standard, timing of 2021 or 2022. 4. PJM is working with distribution utilities and others towards achieve consensus to publish in Q 4 2019 recommendations for state/local authorities and distribution utilities regarding the ride through and trip portions of the IEEE 1547 -2018 standard. www. pjm. com 10 PJM© 2019

Why Ride Through--Wide Area Undervoltage Could Affect Lots of DER Multiphase transmission faults wide area undervoltage 40 miles > 1, 000 ~ 1 MW GW non-wholesale solar ~ 6 on GW load solar busses w/ V <54% www. pjm. com 12 Under high deployment, DER should “ride through”, i. e. stay connected, for low voltages from transmission faults PJM© 2019

Why Ride Through—DER and Frequency Excursions Catastrophic islanding of interconnection Unusually Big Gen Loss Black start Loss of 4, 500 MW in Eastern Interconnection in August 2007 PJM in August 2003 www. pjm. com 13 PJM© 2019
