COOPERATIVE CONTROL SYSTEM AND COOPERATIVE CONTROL METHOD FOR IT DEVICE AND BATTERY

摘要

High efficiency of charge/discharge of a battery is realized by estimating characteristics (time frequency interval and the like) of an expected power outage in advance and cooperatively controlling an IT device and an uninterruptible power supply unit having a battery for the assumed power outage. It includes a commercial power supply 10 a voltage logger 20 which measures a voltage of the commercial power supply an uninterruptible power supply unit 30 to which a plurality of batteries 32 a power strip 40 with power measurement mechanism a plurality of IT devices 50 including a server 51 connected to the power strip. A control unit 55 in the server estimates a continuous duration of a future power outage obtains a power limiting value of the IT device using residual capacity of the battery and the estimated continuous duration of the power outage and controls power of the IT device....
