Project-2021-04-Modifications-to-PRC-002-2

 

Board Adopted: October 8, 2024

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. A new Standard PRC-028-1 - Disturbance Monitoring and Reporting Requirements for Inverter Based Resources has been developed to cover the IRPTF SAR work scope.

Standard(s) Affected – PR​C-002-4​ 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.
