降低成本在构建和运营数据中心方面起着至关重要的作用。Facebook和谷歌等互联网服务提供商花费数十亿美元用于其全球数据中心的容量扩展和运营。传统上，数据中心的容量规划是与运营管理分开进行的，这会导致效率低下。事实上，运营管理对容量规划有着重大影响。基于这一差距，我们提出了一个框架，共同优化可持续数据中心和参与需求响应计划的数据中心的容量规划和运营管理。基于真实案例的数值结果表明，与传统方法相比，所提出的框架显着减少了高达50%的总支出和75%的温室气体排放。此外，我们的研究结果表明，参与各种需求响应计划导致截然不同的能力规划决策，并导致高达60%的减排。
Reducing costs plays a crucial role in building and operating data centers. Internet service providers such as Facebook and Google spend billions of dollars on capacity expansion and operations of their global data centers. Traditionally, capacity planning for data centers is done separately from operational management, which incurs inefficiency. In fact, operational management has significant impacts on capacity planning. Motivated by this gap, we propose a framework that jointly optimizes both capacity planning and operational management for sustainable data centers and data centers participating in demand response programs. Numerical results based on real-world cases highlight that the proposed framework remarkably reduces up to 50% of total expenditures and 75% of greenhouse gas emissions compared to conventional methods. Additionally, our results show that participations in various demand response programs result in vastly different capacity planning decisions and lead to emission reductions of up to 60%.
