Urgent: | Yes |
Sections: | 2.9.1 |
Description: | This Nodal Operating Guide Revision Request (NOGRR) proposes a requirement for Voltage Ride-Through (VRT) capability for new IRRs |
Reason: | This NOGRR is being proposed for the following reasons: Due to the expected IRRs to be placed in service over the next few years, lack of VRT capability could pose ERCOT reliability issues in the event of voltage excursions. Concern of sudden voltage changes causing tripping of units without VRT capability. Additionally, although the VRT study indicated there was no need to retrofit existing Wind-powered Generation Resources to add VRT capability, the concern remains if more units without VRT capability are placed in service, especially in west Texas where many existing WGRs do not have VRT capability. |
