Forced Oscillations in Power Systems Induced by Data Centers Hosting AI Workloads
Jovan Krajacic, Georgia Pierrou, Maitraya Desai +2
Power swings in large Data Centers (DTCs) running Artificial Intelligence (AI) workloads can excite poorly damped modes in power systems. The resulting forced oscillations can lead…
Mitigating Forced Oscillations in Power Systems via Data-Enabled Predictive Control
Soraya Daabak, Verena Häberle, Gabriela Hug +1
Sustained forced oscillations in power systems, driven by large cyclic loads such as data centers, pose a challenge to conventional power system stabilizers (PSSs), which rely on f…
Comparative Assessment of Frequency Scans using EMT and RMS Models
Clea Bürgel, Gustavo Valverde, Gabriela Hug
Frequency scans of inverter and grid impedances are crucial for assessing small-signal stability and system strength in inverter-dominated power systems. This paper compares freque…
Loadability Limits Under Periodic Load Forcing
Maitraya Avadhut Desai, Gustavo Valverde, Gabriela Hug
The static loadability limit, defined as the demand at which the equilibrium equations lose their solution, is the standard basis for interconnection screening of large new loads.…
TSO-DSO Coordination for Flexibility Management Across Voltage Levels
Gustavo Valverde, Anibal Sanjab, Florin Capitanescu +4
Several sources of flexibility in transmission and, especially, distribution networks are being unlocked by advances in information and communication technologies, aggregators, and…
Residential Peak Load Reduction via Direct Load Control under Limited Information
Katharina Kaiser, Gustavo Valverde, Gabriela Hug
Thermostatically controlled loads and electric vehicles offer flexibility to reduce power peaks in low-voltage distribution networks. This flexibility can be maximized if the devic…
Revisiting Power System Stabilizers with Increased Inverter-Based Generation: A Case Study
Jovan Krajacic, Keith Moffat, Gustavo Valverde
As power systems evolve with increasing production from Inverter-Based Resources (IBRs), their underlying dynamics are undergoing significant changes that can jeopardize system ope…
