Reliability Guideline: Bulk Power System Reliability Perspectives on the Adoption of IEEE Std 1547-2018
The guideline, Bulk Power System Reliability Perspectives on the Adoption of Institute of Electrical and Electronics Engineers Standard 1547-2018 (IEEE Std 1547-2018), aims to provide high-level guidance and bulk power system reliability perspectives that should be considered during the adoption and implementation of IEEE Std 1547-2018.
Reliability Guideline: Bulk Power System Reliability Perspectives on the Adoption
of IEEE Std 1547-2018 (NERC 2023)
The guidance provided in this resource from the North American Electric Reliability Corp. (NERC) is intended for state regulatory staffs, distribution providers, balancing authorities,
reliability coordinators, and other entities navigating adoption of IEEE Std 1547-2018
and its requirements. This NERC guideline is not intended to suffice as engagement
or coordination among reliability coordinators and other stakeholders nor intended
to address regionally specific consideration; rather, it is intended to serve as a
useful reference in these coordination activities.
Topics Covered
This guideline provides a bulk power system perspective that should be considered during the adoption and implementation of IEEE Std 1547-2018. While this guideline does not cover every clause of IEEE Std 1547-2018, it does address benefits of the standard related to bulk power system reliability.
- Voltage and frequency mandatory trip settings
- Ridethrough capability
- Distributed energy resource (DER) enter service and return to service operation
- DER controls configuration
- Interoperability and local DER communication interface considerations
Key Takeaways
Coordination on Settings
NERC encourages collaboration at the state-level and regional-level to engage all necessary stakeholders. The stated goal, according to this guideline, is that involvement from all interested stakeholders "will lead the state regulatory entities and [distribution providers] to successful selection of appropriate settings within IEEE Std 1547-2018 and appropriate enforcement of the standard across all DERs connecting to their grid."
Addressing Diverging Objectives
In this guideline, NERC points out the "natural diverging objectives between transmission and distribution system operation" and notes that IEEE Std 1547-2018 addresses this by requiring coordination between distribution providers and regional reliability coordinators.
Adoption
NERC reliability guidelines are not binding norms or parameters, as are NERC's Reliability Standards which are monitored or enforced; their incorporation into industry practices is strictly voluntary. Nonetheless, NARUC (National Association of Regulatory Utility Commissioners) referenced a draft of this guideline in its resolution Recommending State Commissions Act to Adopt and Implement Distributed Energy Resource Standard IEEE Std 1547-2018, NARUC (2020).
Pursuant to Federal Energy Regulatory Commission (FERC) Order 174 FERC ¶ 61,030 (2021), NERC reliability guidelines now include metrics. The committee responsible for this guideline references the ongoing data collection and monitoring work hosted by the IEEE SCC21 group that tracks the adoption of 1547-2018 for these metrics.
Working With Bulk Power System Stakeholders on Interconnection Policies
Examples of stakeholder processes which included coordination on ride-through capability requirements, regional voltage and frequency trip settings, and other advanced DER features are cited. These include:
