CSR: Medium: Provisioning and Harnessing Energy Storage for Datacenter Demand Response

电力消费的消费者提出了经济，社会和环境问题。大型数据中心每年花费数百万美元的运营支出（op-ex）来支付其电费，并提供电力输送网络，以适应峰值电力消耗，即使这种消耗很少持续。在时间上（随着时间）和空间上（跨数据中心的区域，或者甚至跨数据中心）重新整形功率汲取，广义上称为需求响应（DR），是降低cap-ex和op-ex成本的常用技术。到目前为止，数据中心灾难恢复主要使用计算旋钮--整合、调度、迁移和电源状态调制--来管理功耗。该项目将研究一套新的补充技术，利用能源存储设备（ESD）在数据中心的DR。该项目将探讨与供应的具体问题-类型，容量和位置-在数据中心的电源层次结构中的ESD。它还将开发从这些设备采购的控制技术，并将其使用与当前的计算DR技术相结合，同时优化性能，成本，可用性和ESD健康相关标准。这项研究将对降低数据中心的电力成本和获得可再生能源的能力产生直接影响。本研究所建立的平台、模型和电源线对进一步研究静电放电有一定的参考价值。这个项目也将加强相关领域的跨学科课程，并导致新的本科生荣誉的论文项目。

Power consumption of datacenters poses economic, societal and environmental concerns. A large datacenter spends millions of dollars in yearly operational expenditures (op-ex) paying its electricity bills, and in provisioning the power delivery network, to accommodate the peak power draw, even if this draw is rarely sustained. Re-shaping the power draw temporally (over time) and spatially (across regions of the datacenter, or even across datacenters), broadly referred to as Demand Response (DR), is a common technique to reduce cap-ex and op-ex costs. Until now, datacenter DR has primarily used computing knobs -- consolidation, scheduling, migration, and power state modulation -- to manage the power draw. This project will investigate a novel set of complementary techniques leveraging Energy Storage Devices (ESDs) in the datacenter for DR. The project will explore specific issues related to provisioning -- type, capacity and location -- ESDs in the datacenter power hierarchy. It will also develop control techniques for sourcing from these devices, and coupling their usage with current computing DR techniques, all the while optimizing for performance, cost, availability and ESD health related criteria. This research will have a direct impact on datacenter power cost reduction and the ability to source renewable energy. The platforms, models and power traces from this work can be useful to further ESD research in datacenters. This project will also enhance interdisciplinary curriculum in the related areas, and lead to new undergraduate honor's thesis projects.
