Status
The NERC Inverter-Based
Resource Performance Subcomittee (IRPS) submitted Revisions to FAC-001-4 and
FAC-002-4 Standard Authorization Request (SAR) has been authorized for
reassignment to Project 2023-05 Modifications to FAC-001 and FAC-002 by the Standards Committee (SC) on March 19, 2024. Comments submitted during the prior formal comment period will be preserved and shared with the Project 2023-05 drafting team.
The Project 2022-04 EMT Modeling drafting team will continue to address the EMT Modeling SAR that proposes including EMT models and studies in planning-related NERC Standards to ensure reliable operation of the BPS moving forward.
Background
The bulk power system (BPS) in North America is undergoing a rapid transformation towards high penetrations of inverter‐based resources. Transmission Planners (TP) and Planning Coordinators (PC) are concerned about the lack of accurate modeling data and the need to perform electromagnetic transient (EMT) studies during the interconnection process and long‐term planning horizon. The growth of inverter technology has pushed conventional planning tools to their limits in many ways, and TPs and PCs are now faced with the need to conduct more detailed studies using EMT models for issues related to inverter-based resource integration issues.
Standard(s) Affected: FAC-001, FAC-002, MOD-032, and TPL-001
Purpose/Industry Need
As
the scope of this project relates to Milestone 3 Standards Development projects,
but has no assigned FERC directives from Order No. 901, this project will be
developed in tandem with Milestone 3 projects, but is not considered a
Milestone 3 project.
This project addresses the reliability‐related need and benefit by ensuring TPs and PCs have the models and tools necessary to adequately conduct reliability assessments under increasing levels of inverter‐based resources. This requires the collection of EMT models by applicable entities and TPs and PCs to conduct EMT studies where needed.
