advancing grid forming technology since 2022

What we do

Unifi is developing technologies to guarantee the interoperability of grid-forming (GFM) power electronics deployed on the grid to ensure reliability, security, and affordability. We bring together leading researchers, industry stakeholders, utilities, and system operators to unify the integration and operation of inverter-based resources and synchronous machines. Unifi conducts and coordinates research, development, and demonstration, as well as creates educational- and workforce-training materials focusing on planning, designing, and operating grids with a high level of GFM.
