Group Manager and Principal Engineer

Orcid ID

Bryan Palmintier is the Group Manager of the Transmission & Distribution Interactions Group in the Grid Planning and Analysis Center. He has 25 years of experience with integrating multi-domain models and hardware testing spanning electric power systems, larger multi-energy systems (including transportation, buildings, water, etc.), and aerospace systems. He currently focuses on advanced tools and approaches for integrating distributed energy technologies in the power system. This work recognizes the importance of capturing not only the purely technical aspects, but also the social, economic, and regulatory interactions to accurately understand and model modern complex engineering systems, such as the U.S. energy system. Bryan also has extensive experience leading teams from technical projects to outdoor expeditions.
