DOE i2X Season 2
ESIG in collaboration with Berkeley Lab, is supporting the U.S. Department of Energy (DOE) initiative to facilitate the Forum for the Implementation of Reliability Standards for Transmission (FIRST) as part of the DOE’s Interconnection Innovation e-Xchange (i2X).
To ensure the reliable and secure operation of energy resources connected to the electric grid, interconnection standards need to address inverter-based generator capabilities, expected performance, cybersecurity requirements, and other relevant issues. Some of these standards, such as Institute of Electrical and Electronics Engineers (IEEE)-2800, have been developed, but still need to be widely adopted and implemented. Other standards, as well as procedures for assessing and verifying plant conformity with them, have yet to be developed.
The U.S. Department of Energy (DOE) Interconnection Innovation e-Xchange (i2X) Forum for the Implementation of Reliability Standards for Transmission (FIRST) facilitates the adoption of new and recently updated standards relevant for interconnected energy resources. The Forum convenes industry stakeholders to enable easier and more harmonized implementation of these interconnection standards. i2X FIRST addresses the solutions related to interconnection standards (4.2 to 4.9) identified in the DOE Transmission Interconnection Roadmap. i2X FIRST covers practices outlined in the draft of IEEE P2800.2 and best practices from early adopters of the IEEE 2800 standard. Additionally, ongoing North American Electric Reliability Corporation (NERC) standard revision efforts related to Federal Energy Regulatory Commission (FERC) Order 901 are discussed to ensure alignment with IEEE 2800 adoption. Feedback gained through i2X FIRST will help shape new standards development processes.

DOE i2X FIRST Grid-Forming Inverter Workshop Introduction
View Session Recording: Introduction and Session 1
- Workshop Introduction
Julia Matevosyan, Associate Director, Chief Engineer, ESIG - U.S. DOE i2x Next Steps
Cynthia Bothwell, Boston Government Services, contractor to DOE
Session 1 – Basics of Grid-Forming Inverter-Based Resources
What is a grid-forming (GFM) inverter-based resource (IBR); how it is different from state-of-the-art grid following (GFL) IBRs; what GFM control exists; what are capabilities and limitations of GFM IBRs.
- GFM Tutorial Part 1
Andrew Isaacs, Vice President, Electranix (Canada) - GFM Tutorial Part 2
Deepak Ramasubramanian, Principal Technical Leader, Electric Power Research Institute (EPRI)
Session 2 – System Needs for Grid Forming Capabilities
Session Chair: Alex Shattuck, Director of Grid Transformation, ESIG
What prompts system operators to consider grid forming technology; what studies are carried to out identify if GFM is needed, where and how much is needed; what other considerations are necessary when determining the need for GFM requirements; what are other options that could be considered; have system operators looked at fully utilizing GFL IBR capabilities as per IEEE 2800-2022, how can system operators monitor and verify that GFM capabilities are indeed provided?

Session 3 – Grid Forming Requirements
Session Chair: Julia Matevosyan, Associate Director, Chief Engineer, ESIG
Increasingly, in the areas with high shares of IBRs and that have a determined need for GFM capabilities, system operators are coming up with requirements for GFM IBRs. What do these requirements entail, how are they formulated, do they apply to specific technologies or all IBRs and why, how is conformity with these requirements going to be evaluated?
- GFM Requirements at HECO, AEMO, ERCOT, MISO, etc.
Andrew Isaacs, Vice President, Electranix (Canada) - UNIFI GFM Requirements
Dominic Gross, Associate Professor, University of Madison-Wisconsin - Frequency Domain Specifications for Grid-Forming Resources

Session 4 – Global Landscape of Grid Forming Projects
Session Chair: Julia Matevosyan, Associate Director, Chief Engineer, ESIG
There is a growing number of GFM IBRs and other GFM devices being installed around the world, what are the main drivers; what are main challenges and gaps during interconnection process and after commissioning?
