Abstract: A data center (DC) user device manages user power consumption in a time unit, and stores the user power consumption in a power consumption table. A DC provider device manages provider power consumption in a time unit and stores the provider power consumption in the power consumption table. A power retailer device measures provider power consumption for a certain period, and determines retailer power consumption when a measurement value of the provider power consumption is equal to a total value of all user power consumptions.

Abstract: To reduce a power surplus of fluctuating renewable energy. Data center candidate management information indicates a characteristic of renewable energy supplied to each data center candidate. Application program type candidate management information indicates a characteristic of each application program type candidate. The system determines, with reference to the data center candidate management information and the application program type candidate management information, a plurality of combinations each including one or more data center candidates and one or more application program type candidates, determines a score of each combination based on a characteristic of renewable energy supplied to each of the one or more data center candidates and a characteristic of each of the one or more application program type candidates, and selects, based on the score, a combination to be presented.

Abstract: The invention achieves an increase in speed and optimization of a cooperative operation plan creation work between a data center operator and a user. In an operation plan creation method in a data center, an operation plan server calculates a handling cost to handle a given consumption pattern of a DC user when an operation plan of a created workload (WL) is to be created or changed, and creates an operation plan optimization equation for maximizing or minimizing an index such as a cost including the handling cost. At this time, a solution of the operation plan optimization equation is obtained such that a consumption pattern obtained by changing a consumption pattern in a past response history of the user according to a certain rule is available at a handling cost to handle the changed consumption pattern, thereby creating an operation plan draft for the consumption pattern of the user and a device held by a data center operator. The operation plan server confirms, to a WL execution management server, whether the operation plan draft can be executed, and instructs the WL execution management server to execute the operation plan draft.
