Last month, the Federal Energy Regulatory Commission released its Notice of Proposed Rulemaking (NOPR) under "Docket No. RM25-3-000: Reliability Standards for Frequency and Voltage Protection Settings and Ride-Through for Inverter-Based Resources." With responses due by mid-February, this is an exciting and pivotal moment for renewable energy and #GridReliability! Here are some key takeaways and questions from the proposed standards: 1️⃣ Initial Reliability Focus for #IBR Plants – PRC-024-4 and PRC-029-1 are central to this rulemaking. Could this be just the beginning of more comprehensive requirements for IBR plant reliability? 2️⃣ Performance vs. Guidelines for Assessment – While the standards emphasize actual plant performance, they provide limited guidance on how compliance will be assessed. Will modeling, design evaluations, and real-world performance validation all play a role? 3️⃣ Evidence for Compliance – PRC-029-1 outlines compliance through dynamic simulations, plant protection settings, and actual disturbance monitoring. Yet the challenge remains: 🔹 Can we avoid a future where “models perform” when “plants do not”? 🔹 How do we ensure that simulations and designs translate into real-world reliability? The forthcoming #IEEE P2800.2 aims to provide test and verification procedures for IBRs, focusing on: ▪️ Design Evaluations ▪️ Modeling and Simulation ▪️ Field Testing As the industry pushes forward with fast-track IBR projects, the balance between simulation confidence and field validation is critical. Let’s prioritize field testing and post-commissioning monitoring to bridge the gap between theoretical and operational reliability. What are your thoughts on these developments? Will compliance with these standards move the industry closer to resilient grid integration for IBRs? #FERC #EnergyStandards #InverterBasedResources #PowerSystems #EnerNex
