Project 2022-02 Uniform Modeling Framework for IBR will address 24 regulatory directives from FERC Order No. 901 – Milestone 3, Phase one. Specifically, modeling and data sharing requirements to establish sufficient IBR model data and parameters to assure accurate representation of IBR performance within the models. This project is intended to establish new or revised Reliability Standards to ensure the usage of a uniform framework for data sharing and model development. This uniform framework is to ensure the directives of Order No. 901 can be effectively met to ensure usage of generic model types for IBR in the Interconnection-wide models.
This project must ensure modeling revisions from other IBR performance requirements in other 901-related projects will utilize the uniform framework. For instance, performance of IBR during an event (grid disturbance) is identified and corrected within Milestone 2 of FERC Order No. 901. Evaluated performance within new PRC-029 or PRC-030 may necessitate some form of change to how specific IBRs are represented in the model; as the IBR should be modeled based on how it performs during a disturbance and/or new/changed equipment as a result of failing to ride through. However, any requisite changes to model data as a result of correcting IBR performance, must be communicated through a uniform model framework to assure all impacted entities and users of the approved models are adequately informed and provided updated models (as developed within this project). This project, Milestone 3 Phase one, will establish the uniform framework for data sharing and model development of future Order No. 901 related projects that will utilize performance data.
This project has been identified as high priority at this time. The project has a FERC deadline of November 4, 2025.
Standard(s) Affected for Phase One: MOD-032, IRO-010, and TOP-003
Background for Phase Two
Due to the priority of FERC Order 901 directives, the TPL-001 SARs will be addressed during Phase two for Project 2022-02 and is not expected to be a high priority project. While the current DT of Project 2022-02 is working on the project, a new SAR related to TPL-001-5.1 was approved for posting by the Standards Committee. The Standards Committee asked the current DT to include this SAR as part of the project rather than creating a new project. The new SAR will address Footnote 13d issue in Standard TPL-001-5.1. Please see the TPL-001 SAR for additional information.
Standard(s) Affected for Phase Two: TPL-001-5.1 and MOD-032-1
Purpose/Industry Need
Phase One
Phase one will provide industry with a uniform framework for each Interconnection that includes a minimum modeling criteria consistent with NERC's Dynamic Modeling Recommendations, a registered modeling designee, and necessary data exchange requirements.
Phase Two
Phase two will provide clarity, or in some cases, expand the scope of requirements when considering the performance of DERs to ensure the accuracy of Transmission System Planning Assessments.
