Exploring Highly Dependable and Efficient Datacenter Power System Using Hybrid and Hierarchical Energy Buffers

The massive and irregular load surges challenge datacenter power infrastructures. As a result, power mismatching between supply and demand has emerged as a crucial availability issue in modern datacenters which are either under-provisioned or powered by intermittent power sources. Recent proposals have employed energy storage devices such as the uninterruptible power supply (UPS) to address this i...
