Dr. Yilu Liu attended the 2026 IEEE Power & Energy Society International Meeting (PESIM 2026) held in Hong Kong on January 18-21, 2026. The PESIM 2026 topic was Global Power and Energy Systems Resilience: Leveraging Collaborative Expertise.
Dr. Liu, along with Dr. Lin Zhu of the Electric Power Research Institute (EPRI), co-chaired a session entitled Inertia and Fast Frequency Response Estimation Practices for High RBI Grids. Joining Dr. Liu and Dr. Zhu as a panelist was Dr. Fran Li, University of Tennessee Director of CURENT.
Below is the session abstract published in the program:
With the increase of inverter connected generation, load, and storage, and the retirement of coal and oil plants, system inertia could reduce significantly. Some of the IBR could provide fast frequency response if required. It becomes necessary to know how much inertia is in the system at a given time to ensure sufficient mechanisms in the system to recover the frequency in case of power imbalance caused by generation drops or large load rejection. This panel will feature experts worldwide to share their experience in performing inertia or fast frequency response estimation in actual power grids in US, UK, and island grids. The panel will also feature recent exploration of scheduling of virtual inertia to incorporate dynamic frequency response in high-penetration IBR systems.
