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.

online Short course: gfm 101
Join us for this interactive 5-day online short course designed for professionals across utilities, vendors, system operators, and researchers.
✅What You’ll Learn: Each two-hour session combines lecture and EMT simulation exercises, so you don’t just hear the theory—you practice it.
💡Why Join: Comprehensive lectures + real-world simulation exercises. Earn 1 CEU upon completion.
🗓️ When: November 3 – 7, 2025 | 11 AM – 1 PM (Central) each day
Discount available for UNIFI members (email Michelle Hunt for details: michelle.hunt@ieee-isto.org)
Module 1 – The Power Grid: Past to Future: How the grid works today, why inertia matters, and how DC-AC inverters use PWM to create stable AC power. (EMT Lab: Build AC from DC using a half-bridge PWM setup.)
Module 2 – Feedback Control Fundamentals: Zero-error tracking, PI controllers, and reference frames for modeling/control. (EMT Lab: Add a current-control feedback loop and tune bandwidth for dynamic response.)
Module 3 – Grid-Following Inverters: PLL concepts, strengths and weaknesses, and real-world applications. (EMT Lab: Connect to the grid and watch instability during weak-grid or islanded operation.)
Module 4 – Grid-Forming Inverters: Primary control, voltage/current control, and power sharing without a PLL. (EMT Lab: Explore islanding mode and run a single-inverter infinite-bus study.)
