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.…
Dynamic Optimization of Virtual Inertia and Damping in Converter-Based Power Systems
Jovan Krajacic, Maitraya Avadhut Desai, Ognjen Stanojev +1
The transition towards a sustainable power system is enabled by the replacement of conventional synchronous generators with converter-interfaced renewable energy sources. However,…
Next-Generation Grid Codes: Towards a New Paradigm for Dynamic Ancillary Services
Verena Häberle, Kehao Zhuang, Xiuqiang He +3
This paper introduces a conceptual foundation for Next Generation Grid Codes (NGGCs) based on stability and performance certificates, enabling the provision of dynamic ancillary se…
Network-Independent Incremental Passivity Conditions for Grid-Forming Inverter Control
Jared Miller, Maitraya Avadhut Desai, Xiuqiang He +2
Grid-forming inverters control the power transfer between the AC and DC sides of an electrical grid while maintaining the frequency and voltage of the AC side. This paper focuses o…
