Multi-Timescale Deliverability of Shared Hybrid Storage for AI Data Center Campuses
Zihan Meng, Ruizhang Yang, Chenxi Hu +1
Artificial intelligence data center (AIDC) campuses contain sustained power variations and subsecond power fluctuations, requiring both sufficient stored energy and fast response.…
Frequency-Calibrated Decision-Focused Learning for BESS Dispatch Under Renewable Uncertainty
Zihan Meng, Chenxi Hu, Xin Cui +1
Battery energy storage system (BESS) flexibility depends on state of charge and intertemporal operating constraints. Renewable forecast errors of similar magnitudes can lead to dif…
Data Center Load Accommodation under QoS and Checkpoint-Induced Frequency Security Constraints
Ruolan Cui, Ziang Liu, Chenxi Hu +1
The rapid growth of artificial intelligence workloads is accelerating the expansion and grid interconnection of data centers (DCs). Existing data center load accommodation (DCLA) a…
Privacy-Preserving Coordinated Operation of Power Grids and AI Data Centers: A Checkpoint-Aware Three-Phase Scheme
Ziang Liu, Ruizhang Yang, Xin Cui +1
The rapid growth of large language model training and serving is driving AI data centers (AIDCs) toward gigawatt scale. Unlike conventional commercial loads, AIDCs possess signific…
Quantum-Resilient Distributed Optimization for Multi-Region Unit Commitment
Junhong Liu, Qinfei Long, Alex Pengfei Zhao +4
Multi-region unit commitment with reserve sharing requires coordinated optimization across jurisdictionally distinct system operators, exposing sensitive cost curves, topology, and…
Adaptive Federated Learning to Optimize Integrated Flows in Cyber-Physical Data Centers
Junhong Liu, Lanxin Du, Yujia Li +4
Data centers play an increasingly critical role in societal digitalization, yet their rapidly growing energy demand poses significant challenges for sustainable operation. To enhan…
Synergising Hierarchical Data Centers and Power Networks: A Privacy-Preserving Approach
Junhong Liu, Fei Teng, Yunhe Hou
