Power management system, power management device, and large power-using power load
First Claim
1. A power management system comprising:
- a power management device including a processor and configured to manage power to be used by multiple power loads; and
a large power-using power load which is one of the multiple power loads,the large power-using power load being defined as a power load which shows a power consumption larger than a difference between allowable power regarding a total power consumption of the multiple power loads and an upper limit power regarding the total power consumption which is smaller than the allowable power when operating at a maximum power consumption,the processor including;
a setting unit configured to set the upper limit power;
an acquiring unit configured to acquire the total power consumption given by a measurement value from a measurement unit configured to measure the total power consumption;
a calculating unit configured to calculate remaining available power which is available for the large power-using power load, from the upper limit power set by the setting unit and the total power consumption acquired by the acquiring unit; and
a notification unit configured to notify the remaining available power calculated by the calculating unit, to the large power-using power load, andthe large power-using power load including;
a power-using load configured to perform a predetermined operation by using power; and
an operation controller configured to allow the power-using load to start to operate under a condition that a power consumption of the power-using load is equal to or less than the remaining available power notified by the power management device.

Abstract
The power management system includes: a power management device for managing power to be used by multiple power loads; and a large power-using power load. The large power-using power load is defined as a power load which shows a power consumption larger than a difference between allowable power and an upper limit power smaller than the allowable power when operating at a maximum power consumption. The power management device calculates remaining available power available for the large power-using power load, from the total power consumption of the multiple power loads and the upper limit power, and notifies the remaining available power to the large power-using power load. The large power-using power load starts to operate under a condition that its power consumption is equal to or less than the remaining available power notified by the power management device.

19. A power management method for managing power to be used by multiple power loads,
the multiple power loads including a large power-using power load, the large power-using power load being defined as a power load which shows a power consumption larger than a difference between allowable power regarding a total power consumption of the multiple power loads and an upper limit power regarding the total power consumption which is smaller than the allowable power when operating at a maximum power consumption, the power management method comprising: -
setting the upper limit power; acquiring the total power consumption; calculating remaining available power which is available for the large power-using power load, from the upper limit power and the total power consumption; and allowing the large power-using power load to start to operate under a condition that a power consumption of the large power-using power load is equal to or less than the remaining available power. - View Dependent Claims (20)
