Time Distribution Principle Using Measured Traveling Waves in Power Grid
Haozong Wang, Yayu Yang, Jiahui Yang +5
Accurate time synchronization is essential for distributed systems. Conventional methods, such as satellite-based synchronization and communication-based approaches, face challenge…
Keeping Data Centers Online in Weak Grids: PLL-Free VM-DPC With Adaptive Reactive-Power Support for Centralized UPS Systems
Jesus D. Vasquez-Plaza, Yonghao Gui, Jin Dong +2
Data center power systems are increasingly exposed to weak-grid conditions due to the rapid growth of converter-dominated networks and highly dynamic artificial intelligence (AI) w…
Critical Inertia Estimation for the Three U.S. Interconnections
Jiaojiao Dong, Sneha Fariha, Rocio Uria Martinez +2
The rapid integration of inverter-based resources (IBRs) is reducing system inertia across U.S. power grids, raising concerns about frequency stability following large contingencie…
Frequency Response of Windowed DFT Phasor Estimation: Impact on Oscillation Observability
Jiahui Yang, Yuru Wu, Haozong Wang +4
Phasor measurement units (PMUs) are widely used for sub-synchronous oscillation monitoring, yet the effect of windowed discrete Fourier transform (DFT)-based phasor estimation on o…
Understanding Regional Inertia Dynamics in CAISO from Real Grid Disturbances
Saurav Dulal, Mohammed M. Olama, Ali R. Ekti +2
The shift from synchronous generators to inverter-based resources has caused power system inertia to be unevenly distributed across power grids. As a result, certain grid regions a…
