TL;DR
A deep reinforcement learning (DRL) framework that jointly co-schedules computing and thermal resources so that a hyperscale data center can operate as a grid-interactive flexible load and supports the evolution of hyperscale data centers from passive electricity consumers toward active, grid-interactive participants in renewable-penetrated power systems.
Abstract
Driven by artificial intelligence and cloud computing, hyperscale data centers are becoming one of the fastest-growing electrical loads worldwide and are increasingly recognized as a new class of flexible loads capable of supporting demand response (DR) and the integration of variable renewable energy (VRE). However, their two principal control levers—IT workload scheduling and cooling system operation—have traditionally been managed in a decoupled manner, leaving both energy efficiency and demand-side flexibility under-exploited. This paper proposes a deep reinforcement learning (DRL) framework that jointly co-schedules computing and thermal resources so that a hyperscale data center can operate as a grid-interactive flexible load. We formulate the joint problem as a constrained Markov Decision Process and develop an actor-critic algorithm combining Deep Deterministic Policy Gradient with a safety shield mechanism to guarantee thermal constraint satisfaction during both training and deployment. A high-fidelity digital twin simulation environment enables safe Sim-to-Real training. Extensive experiments demonstrate that the proposed approach reduces total electricity consumption by 18-25% compared to baseline controllers, cuts thermal violations by over 90%, and maintains service level agreement compliance, while broadening the controllable power envelope of the facility to provide a technical basis for participating in DR programs and aligning data-center power profiles with renewable generation. The framework bridges IT-side and facility-side control and supports the evolution of hyperscale data centers from passive electricity consumers toward active, grid-interactive participants in renewable-penetrated power systems.
This paper proposes an edge-cloud collaborative physics-informed reinforcement learning framework for production data center HVAC control that integrates a physics-informed cold-start solution using Adaptive Particle Swarm Optimization, a three-time-scale edge–cloud architecture, and a constraint-aware safe projection layer that embeds thermal safety hard constraints directly into the neural network policy.

EDGE-VPP is presented, an end-to-end scheduling framework that connects fine-grained load perception with safety-aware decision-making across multiple temporal scales and achieves the lowest operating cost and the fewest constraint violations among the evaluated scheduling methods.
Large-scale cloud computing environments must continuously allocate, scale, and reconfigure resources under uncertain demand, multi-tenant interference, heterogeneous infrastructure, and stringent service-level objectives. Conventional threshold-based autoscaling remains widely used because of its operational simplicity, yet it often reacts after performance degradation has already occurred. Purely machine-learning-driven methods can improve prediction and adaptation, but they may produce unsafe actions when exposed to distribution shifts, delayed actuation, noisy telemetry, or unobserved dependencies. This paper proposes a hybrid machine learning and control-theoretic framework for stability-assured resource management in large-scale cloud computing environm ents. The framework integrates workload forecasting, online quality-of-service modeling, constrained optimization, feedback control, Lyapunov-style stability reasoning, and policy-governed decision intelligence. The proposed design separates predictive intelligence from safety-critical actuation: machine learning estimates near-future demand, performance sensitivity, and workload classes, while a constrained model-predictive controller and supervisory stability guard transform those estimates into resource actions that respect service-level, cost, and stability constraints. The framework is formulated for containerized and virtualized cloud platforms, including horizontal scaling, vertical resource adjustment, admission control, and workload placement. It defines a conceptual architecture, analytical stability conditions, evaluation metrics, and deployment implications for cloud operators. The analytical discussion shows that a hybrid design can reduce elastic lag, control oscillatory scaling behavior, preserve bounded latency error, and support auditable resource governance more effectively than purely reactive autoscaling or unconstrained learning policies. The paper contributes a structured research model for stability-aware cloud resource management and identifies future directions in safe reinforcement learning, distributed control, explainable autoscaling, and production-grade validation.

The rapid growth of large-scale AI workloads in data centers has placed increasing pressure on power grids in recent years. Since power systems must continuously balance supply and demand, there is growing interests in leveraging data-center workload flexibility as a grid service. We propose a contextual restless multi-armed bandit (CRMAB) framework in which a grid operator requests load reductions without observing internal job-scheduling decisions. Under index-ability guarantee, each data center or physical machine is modeled as a Markov decision process (MDP) over a cyclic virtual-machine (VM) job queue, with unknown rewards and transition dynamics learned online using Thompson sampling and Whittle-index policies. To improve learning under sparse and noisy observations, the framework augments an adaptive Thompson--Whittle (TW) policy with domain-informed transition priors and gated prior mixing. In baseline experiments, the best adaptive refined variant achieves 91.4\% of the oracle reward after 100 rounds and 96.8\% after 1,000 rounds. Across a 16-setting stress test spanning different state-space sizes and levels of contextual noise, the best refined variant consistently outperforms the original TW policy with high confidence while remaining competitive with EXP4. A graph-based prior further incorporates data-center hardware constraints, including computing-resource limits. Overall, the results demonstrate the economic potential of data-center flexibility as a grid service and highlight the importance of high-quality, open-source AI workload traces for developing and evaluating such services.
