Abstract
Official abstract text for this publication.
A data center operable using only electric power based on renewable energy. The data center includes at least one device driven by the electric power, a storage battery for storing the electric power, and a controller for switching the operating mode of the device over the course of time on the basis of predicted values for the amount of electric power generated using renewable energy, the amount of electric power stored in the storage battery, and the amount of electric power consumed by the device.
First claim
Opening claim text (preview).
What is claimed is: 1 . A data center operable using only electric power based on renewable energy, the data center comprising: at least one device driven by the electric power; a storage battery for storing the electric power; and a controller for switching the operating mode of the device over the course of time on the basis of predicted values for the amount of electric power generated using renewable energy, the amount of electric power stored in the storage battery, and the amount of electric power consumed by the device. 2 . The data center according to claim 1 , wherein the controller determines the predicted value B(T) for the amount of electric power stored in the storage battery at time T on the basis of the following formula: B ( T )= B (0)+∫( g ( t )− c ( t )) dt where g(t) is the amount of electric power generated by the renewable energy, and c(t) is the amount of electric power consumed by the device. 3 . The data center according to claim 2 , wherein the controller switches the operating mode of the device to the power saving mode at time T1 having a predicted value B(T) for the amount of electric power stored in the storage battery lower than predetermined threshold value Bth. 4 . The data center according to claim 2 , wherein the controller determines the predicted value g(t) for the amount of electric power generated using renewable energy on the basis of weather forecast data at time t when the amount of electric power generated using renewable energy changes in response to weather conditions in the region including the location of power generation. 5 . The data center according to claim 4 , wherein the electric power generated using renewable energy is supplied by solar power and/or wind power.
