为了适应发电中不断增加的不稳定和间歇性可再生能源，独立系统运营商（ISO）提供需求侧调节服务（RS）的机会，以稳定电网负荷。这些电力市场特征允许需求侧通过在ISO广播的RS信号之后动态地调制其电力消耗来赚取货币信用。本文研究了一个主要的潜在需求方，数据中心，提供RS的能力和效益。我们提出了一个动态的控制策略，利用服务器功率封顶技术和各种服务器的功率状态，调制数据中心的功耗响应ISO请求。结果表明，使用我们的政策，数据中心可以提供快速储备的数量是其平均能耗的相当大的比例（约50%），在服务质量（QoS）没有重大恶化。通过这样做，数据中心的能源成本降低了约50%，同时为ISO和整个社会提供了具有成本效益的需求侧储备，使大规模采用可再生能源发电变得负担得起。
To accommodate the increasing presence of volatile and intermittent renewable energy sources in power generation, independent system operators (ISO) offer opportunities for demand side regulation service (RS) so as to stabilize the grid load. These power market features allow the demand side to earn monetary credits by modulating its power consumption dynamically following an RS signal broadcast by ISO. This paper studies the capacities and benefits of a major potential demand side, the data center, to provide RS. We propose a dynamic control policy that modulates the data center power consumption in response to ISO requests by leveraging server power capping techniques and various server power states. Results demonstrate that using our policy, data centers can provide fast reserves in quantities that are substantial proportions (around 50%) of their average energy consumption, with no major deterioration in quality of service (QoS). By doing so, data centers decrease their energy costs around 50%, while providing the ISOs and the society in general with cost effective demand side reserves that render massive renewable generation adoption affordable.
