Data centres have been the focus of research as candidates for demand response or other demand side management programs for quite some time. However, a complete framework optimising data centre demand response is still missing. This is due to the complexity of integrating more than one power flexibility technology and more than one market for power flexibility. In the presented work, this challenge is solved by creating a microeconomics inspired optimisation approach that takes the view of a data centre offering power flexibility as a ’product’ to explicit and/or implicit demand response power flexibility markets. This generic framework is then instantiated in a linear optimisation problem that optimises the power flexibility of a German High Performance Computing Centre on a set of different power flexibility markets in Germany. It is consequently shown that, under the described scenario, frequency scaling should be preferred to temporal workload shifting and that the EPEX day ahead market is the most beneficial power flexibility market.

从稻草中榨取黄金-评估电力市场数据中心的灵活性

数据中心作为需求响应或其他需求侧管理程序的候选对象已成为研究的焦点。但是，仍然缺少优化数据中心需求响应的完整框架。这是由于集成多个电源灵活性技术和多个电源灵活性市场的复杂性。在提出的工作中，通过创建一种受微观经济学启发的优化方法解决了这一挑战，该方法将数据中心视为提供电源灵活性的产品，作为显式和/或隐式需求响应电源灵活性市场的“产品”。然后，在线性优化问题中实例化此通用框架，该问题可优化德国高性能计算中心在德国一系列不同的电源灵活性市场上的电源灵活性。
