Abstract:

In this paper, we propose a scheduling scheme called GreenFlowing to reduce the electricity cost for a cloud data center by leveraging heterogeneous ESDs. In our model, the data center can be powered by intermittent green energy like wind and solar, and the electricity with time-varying prices from the power grid. The energy from different sources can also choose to flow into long-term or short-term ESDs for later use. Note that, the former can sustain energy for a long time but with low charging/discharging rate, while the latter can charge/discharge very fast but with high energy leakage that can sustain energy only for a few hours. By combining them together, the energy cost can further be reduced. However, it is hard to decide when and how much energy from different sources should be used to power the data center directly or charged into different types of ESDs. We formulate our scheduling into a large-scale linear programming (LP) problem, which can be solved using CPLEX. Numerical experiments show that our scheduling can significantly reduce the total electricity cost for a cloud data center.
