Online Control of Datacenter Power Supply Under Uncertain Demand and Renewable Energy

Modern Cloud Service Providers (CSPs) equip their Datacenter Power Supply System (DPSS) with multisources to mitigate power cost, carbon emission, and power outage: multi-markets grid with time-varying energy prices, finite capacity of Uninterrupted Power Supply (UPS), and certain volumes of intermittent renewable energy. With the presence of uncertain renewable sources and datacenter power demand, CSPs have a critical challenge: how to design systematical online control policies that best utilize different characteristics of multisources in a complementary manner to deliver reliable energy to datacenters while minimizing DPSS operation cost.
