Inverter Based Resource (IBR) Connections to the Transmission Grid; Managing Challenges During a Grid Transforming Evolution
In recent years inverter-based resource (IBR) interconnection requests on the grid have drastically increased. During this time several high-profile IBR disturbance events like those in Odessa, Texas have occurred. Additionally, the NERC Inverter-Based Resource Performance Subcommittee (IRPS) has produced several guidelines recommending Transmission Owners (TOs) collect Electromagnetic Transient (EMT) plant models for IBRs and to perform EMT analysis to ensure reliability of the grid. IEEE produced the 2800 standard for IBR interconnections in 2022 and is working on a 2800.2 standard to define how to implement, verify, and validate that IBR EMT models meet the 2800 standard. Given these developments it is becoming more important for transmission planners to develop the processes and skills to verify EMT models and perform EMT studies. This presentation will explain how ATC has worked to implement NERC recommendations to collect and verify EMT models, perform EMT analysis in the interconnection process, and then to manage post-GIA generator modifications and as-built model changes.
