Reliability Guideline: Bulk Power System Reliability Perspectives on the Adoption of IEEE 1547-2018
The guideline, Bulk Power System Reliability Perspectives on the Adoption of IEEE 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 1547-2018.
Reliability Guideline: Bulk Power System Reliability Perspectives on the Adoption
of IEEE 1547-2018 (NERC 2020)
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 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.
This NERC guideline addresses key clauses in IEEE 1547-2018, in detail, to ensure that the bulk power system reliability perspectives and recommended considerations are made clear.
- 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
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 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 1547-2018 addresses this by requiring coordination between distribution providers and regional reliability coordinators.
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 1547-2018, NARUC (2020).
Working with BPS 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:
