Abstract

The problem of operating the power supply system of a data center in a reliable manner is studied. Two approaches are examined. The first one assumes that there is no control over the power supply system. The second one assumes that there is a control over the maximum capacity of the system load. For the second case, the problem is fitted into a dynamic programming (DP) framework. An optimal control policy is derived, however is intractable. An approximate solution is then constructed by the Perseus algorithm. This solution is compared to two easily implementable heuristic algorithms, and with the case where no system control is allowed. Numerical results show that the approximate solution has a superior performance.
