Reliability Issues with IBRSeveral IBR-based system disturbances have and continueto occur: August 2016 – Blue Cut Fire Disturbance October 2017 – Canyon 2 Fire Disturbance April and May 2018 – Angeles Forest & Palmdale RoostDisturbances July 2020 – San Fernando DisturbanceMay and June 2021 – Odessa, TX DisturbancesDisturbance Analyses and GuidelinesØ Detailed Analysis of IBR-Based disturbancesØ Two Level 2 NERC Alerts Issued with industryrecommendationsØ Reliability Guideline for BPS-connected IBR resourcesØ Odessa Disturbance recommendations call for morethan guidelines3 2022 Electric Power Research Institute, Inc.

Paradigm shift towards the “Good Citizen”Example Reliability Solutions§ Grid Related Solutions§–Transmission upgrades–Innovative transmission assetsIBR Related Solutions–IBR capability requirementsfor new plants–Curtailment of IBR output–Retrofits of existing IBR plants§Software patches§Hardware retrofitsCost allocation§4Status Quo: Integration of capability often subject to service agreementLast resource tends to bear costsØ Integrating a minimum set of IBR capability from the day of plantcommissioning allows for many IBR plants to share the burden andopportunities of a potential future utilization of that capability. 2022 Electric Power Research Institute, Inc.
