Reliability

Addressing challenges in connecting large volumes of new inverter-based resources to resolve the U.S. interconnection queue backlog.

A number of requirements for GFM capabilities have been defined with some requirements at a very high level e.g., HECO and UNIFI, while others are providing more detailed technical specifications e.g., NGESO in Great Britain in their grid code change GC0137. This project team will examine the question of how to test for such requirements…

This is a regularly updated web resource provided by ESIG to track new installations of GFM projects, efforts to define specifications and testing requirements, modeling and model verification, and definitions of system services that GFM IBRs can provide. * * * The majority of inverters today are grid-following (GFL) — they “read” the voltage and…

Defining system needs for the transition to grids dominated by inverter-based resources like wind, solar, and storage.

ESIG has launched a new task force to help utilities organize and execute programs that holistically tackle the multi-faceted technical and operational challenges of integrating Inverter-Based Resources (IBRs) and large loads. We’re seeking active utility participation to ensure this work reflects real-world barriers and best practices in the industry. We are especially interested in engagement…

Evaluating essential reliability service needs in high-IBR grids and identifying how existing resources can help meet them.

Assessing oscillations and stability issues unique to inverter-based resources in large power systems.
