Summary of IBR Webinar 3

The IBR Webinar 3 delved into the challenges and performance issues encountered by industry representatives from Kaiso, TVA, and Urot in managing inverter-based resources (IBRs), particularly solar and battery energy storage. The exponential growth of IBRs in California has led to performance issues like PV solar losses. The history of IBR experiences at OT and TVA revealed challenges with modeling, commissioning, and operational testing.

Mitigation Strategies

Setting grid code requirements early
Ensuring correct modeling
Building stability and EMT study capabilities

Operational Experiences

Insights from past events, such as the Blue Cut fire in California, have prompted the development of reliability standards and tariff language to address industry-wide IBR issues. Operational experiences during commissioning highlighted issues with inverter performance, reactive power control, and communication dropouts.

Importance of Proactive Measures

The presenters stressed the importance of proactive measures, model verification, and real-time monitoring to address IBR performance issues and ensure grid reliability. Collaboration within the industry and adherence to standardized requirements were emphasized as crucial for navigating the energy transition effectively. The webinar also touched on the current tariff, reactive current, and the necessity for standards in the electrical engineering field.

Collaboration and Standardization

The panel underscored the significance of collaboration in developing better standards and addressing industry performance issues. Matching models to actual performance and the role of standardization in enhancing reliability were highlighted. The adoption of standards like 2800 2022 to improve interconnection requirements was discussed. The webinar concluded with a reminder about the upcoming session on establishing and enhancing interconnection requirements.
