项目摘要

The confluence of two powerful global trends, (1) the rapid growth of cloud computing and data centers with skyrocketing energy consumption, and (2) the accelerating penetration of renewable energy sources, is creating both severe challenges and tremendous opportunities. The fast growing renewable generation puts forth great operational challenges since they will cause large, frequent, and random fluctuations in supply. Data centers, on the other hand, offer large flexible loads in the grid. Leveraging this flexibility, this project will develop fundamental theories and algorithms for sustainable data centers with a dual goal of improving data center energy efficiency and accelerating the integration of renewables in the grid via data center demand response (DR) and workload management. Specifically, the research findings will shed light on data center demand response while maintaining their performance, which will help data centers to decide how to participate in power market programs. Further, the success of data center demand response will help increase renewable energy integration and reduce the carbon footprint of data centers, contributing to global sustainability. The PIs will leverage fruitful collaboration to eventually bring the research to bear on ongoing industry standardization and development efforts. The PIs teach courses spanning networks, games, smart grid and optimization, and are strongly committed to promoting diversity by providing research opportunities to underrepresented students. Built on the PIs expertise on data centers and the smart grid, this project takes an interdisciplinary approach to develop fundamental theories and algorithms for sustainable data centers. The research tasks are organized under two well-coordinated thrusts, namely agile data center DR and adaptive workload management. The strategies and decisions of data center DR will be made based on the workload management algorithms that balance quality of service and energy efficiency and determine the supply functions. The workload management algorithms will optimize quality of service under the electric load constraints imposed by DR accordingly. This project will make three unique contributions: (1) new market programs with strategic participation of data centers in DR, instead of passive price takers, (2) fundamental understanding of the impacts of power network constraints on data center DR and new distributed algorithms for solving optimal power flow with stochastic renewable supplies, and (3) high-performance dynamic server provisioning and load balancing algorithms for large scale data centers under time-varying and stochastic electric load constraints and on-site renewable generation.

两个强大的全球趋势的汇合，（1）云计算和数据中心的快速增长，能源消耗飙升，以及（2）可再生能源的加速渗透，正在创造严峻的挑战和巨大的机遇。快速增长的可再生能源发电提出了巨大的运营挑战，因为它们将导致供应的大，频繁和随机波动。另一方面，数据中心在网格中提供了大量灵活的负载。利用这种灵活性，该项目将开发可持续数据中心的基础理论和算法，其双重目标是提高数据中心能源效率，并通过数据中心需求响应（DR）和工作负载管理加速可再生能源在电网中的整合。具体而言，研究结果将揭示数据中心的需求响应，同时保持其性能，这将有助于数据中心决定如何参与电力市场计划。此外，数据中心需求响应的成功将有助于增加可再生能源整合，减少数据中心的碳足迹，为全球可持续发展做出贡献。PI将利用富有成效的合作，最终将研究成果用于正在进行的行业标准化和开发工作。PI教授的课程涵盖网络，游戏，智能电网和优化，并通过为代表性不足的学生提供研究机会来促进多样性。该项目以PI在数据中心和智能电网方面的专业知识为基础，采用跨学科的方法为可持续数据中心开发基础理论和算法。研究任务是在两个协调良好的推动下组织的，即敏捷数据中心DR和自适应工作负载管理。数据中心灾难恢复的策略和决策将基于平衡服务质量和能源效率并确定供应功能的工作负载管理算法。负载管理算法将在DR施加的电力负载约束下相应地优化服务质量。该项目将作出三个独特的贡献：（1）具有数据中心在DR中的战略参与的新市场计划，而不是被动的价格接受者，（2）对电力网络约束对数据中心DR的影响的基本理解以及用于解决具有随机可再生供应的最优电力流的新分布式算法，以及（3）在时变和随机电力负载约束以及现场可再生发电下的用于大规模数据中心的高性能动态服务器供应和负载平衡算法。
