Status

​The formal comment period, initial ballots, and non-binding polls for Project 2021-04 Modifications to PRC-002 – Phase II concluded at 8 p.m. Eastern, Thursday, September 14, 2023 for the following standards and implementation plan:

•    PRC-002-5 – Disturbance Monitoring​ and Reporting Requirements
•    PRC-028-1 – Disturbance Monitoring and Reporting Requirements for Inverter-Based Resources
•    Implementation Plan​

The standard drafting team will review all responses received during the comment period and determine the next steps of the project​


​​​​​Background
This project will be completed in two phases. The first phase addressed the scope regarding notifications relative to the sequence of events recording (SER) and fault recording (FR) data, and to clearly identify the BES Element owners that need to have SER and FR data for transformers and transmission lines with the associated identified bus in the Glencoe Light and Power SAR.

The second phase will address gaps the Inverter-Based Resource Performance Task Force (IRPTF) identified within the PRC-002. The goal is to modify the requirements to ensure adequate data is available and periodically assessed to facilitate the analysis of BES disturbances, including in areas of the Bulk Power System (BPS) that may not be covered by the existing requirements.


Standard(s) Affected PRC-002-3 Disturbance Monitoring and Reporting Requirements

Purpose/Industry Need
The purpose of PRC-002 is to have adequate data available to facilitate analysis of BES disturbances.  Requirements R1 and R5 specify where SER and FR data, and where dynamic Disturbance recording (DDR) data, respectively, are required in the Bulk Electric System (BES).

With the changing resource mix and increasing penetration of IBRs, PRC-002-2 does not serve its intended purpose adequately. To the extent that the standard is already requiring monitoring devices and periodic assessments, the location requirements and associated periodic assessments need to be revised. These revisions are necessary so that required data is available for the purposes of post-mortem event analysis and identifying root causes of large system disturbances.
