"Distributed Economic Dispatch in Power Networks Incorporating Data Center Flexibility" IEEE Transactions on Sustainable Computing, pp.1-15. https://doi.org/10.1109/tsusc.2025.35388172377-3782https://hdl.handle.net/2144/50540We consider Data Centers (DCs) as flexible loads that can alter their power consumption to alleviate congestion in the electric power network. We model DCs using a queuing-theoretic view and we form a Quality of Service (QoS)-based cost function that signifies how well a DC can carry out its workload given an amount of active servers. We integrate DCs in a centralized economic dispatch problem that determines, apart from power generation, DC workload shifting and server utilization, while respecting transmission line constraints. We further present a tractable decentralized formulation obtained via Lagrangian decomposition, which we solve using a dual gradient ascent algorithm. Experimental results on a standard power network explore the system-wide benefits of DC flexibility in “coupled” data and power networks, emphasizing on the trade-offs between the DC location, QoS, and efficiency.pp. 1-15EngineeringInformation and computing sciencesArticle10.1109/tsusc.2025.35388170000-0002-3343-2913 (Paschalidis, Ioannis Ch)1048457
