Information regarding an upcoming NERC Alert Level 3

Upcoming New Standard: PRC-030-1 Unexpected Inverter-Based Resource Event Mitigation

Understanding the NERC Standards Development for Category 2 Inverter-Based Resources (IBR)

NERC Alert: Inverter-Based Resource Model Quality Deficiencies NERC has released a crucial alert addressing significant deficiencies in the modeling and study practices of inverter-based resources (IBR). This comes after analyzing 10 large-scale disturbances since 2016, resulting in nearly 15,000 MW of unexpected IBR output reduction, predominantly occurring between 2020 and 2024. Reporting of these efforts is required by September 2, 2024. Scroll to read the full NERC Alert Article. Key Points: 1) Modeling Deficiencies: Poor modeling practices have been identified as a major contributing factor to these disturbances. Accurate and detailed dynamic models are essential for reliable bulk power system (BPS) operation. 2) Recommendations for Improvement: Model Validation: Models should be validated at both the inverter and plant levels, ensuring they accurately reflect in-service performance. Lifecycle Updates: Continuous updates and validations of models throughout the lifecycle of IBR plants are necessary. Standard and Equipment-Specific Models: Both standard library and equipment-specific models should be used, with rigorous testing and documentation to ensure accuracy. 3) Coordination and Reporting: Generator Owners (GOs), Transmission Planners (TPs), and Planning Coordinators (PCs) must collaborate with manufacturers and third-party consultants to address modeling deficiencies. Reporting of these efforts is required by September 2, 2024.
