About
Modeling and simulation tools that were useful for conventional mechanical equipment must evolve to meet the needs of a modern electric grid that is permeated with power electronics such as inverters. These fast-acting devices are affected differently by faults in distant parts of the grid. In order to plan expansions, interconnections and operations to ensure an uninterrupted power supply, utilities and power system operators need a better understanding of how recent changes in grid architecture will change grid behavior.
Electromagnetic transient (EMT) domain analysis has demonstrated greater accuracy in its ability to reproduce and understand faults in systems with increasing numbers of the inverters required in generation, transmission, storage, and loads (like data centers). Collaboration among researchers, regulators and the power industry is crucial to develop best practices using EMT modeling, combined with other methods and tools, to keep electricity flowing smoothly to customers. As the industry transitions to adopt EMT simulations, there is a need for national-scale collaborations and coordination that may be facilitated through discussions in this workshop and by identifying key research gaps, challenges, and needs for the next decade or more.

Event Description
Description of 2025 Event: Join us in exploring topics related to electromagnetic transient simulations: modeling, simulations, input data structures needed, pre- and post-processing automation to enhance ease of usage, and different applications/studies. The workshop will bring together researchers, consultants, utilities, system operators, and reliability organizations to learn from recent advances in studies and technologies as well as about new initiatives started based on inputs received from the community in the previous workshops. In this edition, there will be tutorials to enhance the knowhow of electromagnetic transient simulations within the community. Finally, participants will be able to provide feedback on the ongoing activities as well as new challenges faced as greater adoption of these simulations happen.
There were 125+ attendees and 40 talks in this 3-day workshop that presented the ongoing R&D to help resolve the gaps and challenges identified in the previous workshops.
