Abstract

A power management apparatus (120) includes management information storage means (121) capable of storing a condition under which each consumer management apparatus (100) receives power (first condition) and a condition under which each consumer management apparatus (100) supplies power (second condition), power control means (123) for supplying or received power to or from the consumer management apparatuses (110), and information control means (122) for controlling the consumer management apparatus (110) and power control means (123). Each consumer management apparatus (110) includes a distributed power supply (111), a load (112), and control means (113) that controls the distributed power supply 112. When the information control means (122) detects that one consumer management apparatus (110) has satisfied the first condition, it requests another consumer management apparatus (100) satisfying the second condition to supply power and supplies the power to the first consumer management apparatus (110) via the power control means (123).

Claims

1. A power accommodation system comprising:

a plurality of consumer management apparatuses forming an autonomously controlled grid; and

a power management apparatus that accommodates power among the consumer management apparatuses, wherein

the power management apparatus comprises;

management information storage unit that stores at least one of first and second conditions in such a manner that the at least one condition is associated with each of the consume management apparatuses, the first condition being a condition under which each of the consumer management apparatuses receives power, the second condition being a condition under which each of the consumer management apparatuses supplies power,

a power control unit that supplies or receives power to or from the consumer management apparatuses; and

information control unit that controls the consumer management apparatuses and the power control unit,

when the information control unit detects that a first consumer management apparatus has satisfied the first condition, the information control unit requests a second consumer management apparatus satisfying the second condition to supply power,

the power control unit supplies power supplied from the second consumer management apparatus to the first consumer management apparatus,

the consumer management apparatuses each comprise at least one of a distributed power supply that generates power and a load that consumes power, and control unit that forms controlling the distributed power supply, and

the control unit controls power supply to the power management apparatus based on a request from the information control unit and received power from the power control unit.

2. The power accommodation system according to claim 1, wherein

the first condition further comprises the energy to be received by each of the consumer management apparatuses, and

the information control unit determines other one or more consumer management apparatuses which should supply power to the consumer management apparatuses and the energy to be supplied by the other consumer management apparatuses on the basis of the energy to be received.

3. The power accommodation system of claim 1, wherein

the second condition further comprises the energy that each of the consumer management apparatuses can supply, and the control unit of each of the consumer management apparatuses drives the distributed power supply in a state in which a reserve generating capacity corresponding to the energy which can be supplied is reserved and causes the distributed power supply to generate power based on the energy which can be supplied, in response to a request from the information control unit.

4. The power accommodation system of claim 3, wherein

when the information control unit detects that the consumer management apparatuses driving the distributed power supply in a state in which a reserve generating capacity corresponding to the energy which can be supplied is reserved have satisfied the first condition, the information control unit supplies power preferentially to the consumer management apparatuses.

5. The power accommodation system of claim 1, wherein the power control unit is a power router capable of outputting received power to one or more specified destinations in specified amounts.

6. The power accommodation system according to claim 5, wherein

the power accommodation system comprises the plurality of power routers connected to one another so that power can be transmitted or received therebetween,

when the information control unit detects that the first consumer management apparatus capable of transmitting or receiving power to or from a first power router has satisfied the first condition, the information control unit determines the second consumer control apparatus that can transmit or receive power to or from a second power router and satisfies the second condition, calculates a power transmission path from the second power router to the firs power router, and notifies the power routers on the power transmission path of the power transmission path, and

the power routers transmit power via the power transmission path.

7. A method for accommodating power comprising:

a step of detecting, by information control unit of a power management apparatus, that a first consumer management apparatus has satisfied a first condition which is a condition under which the first consumer management apparatus receives power;

a step of requesting, by the information control unit of the power management apparatus, the second consumer management apparatus to supply power when a second consumer management apparatus satisfies a second condition which is a condition under which the second consumer management apparatus supplies power; and

a step of receiving, by power control unit of the power management apparatus, the power from the second consumer management apparatus and supplying the power to the first consumer management apparatus.

8. The method for accommodating power according to claim 7, wherein

the first condition further comprises the energy to be received by the consumer management apparatus, and

in the requesting step, the information control unit determines other one or more consumer management apparatuses which should supply power to the consumer management apparatus and the energy to be supplied by the other consumer management apparatuses, on the basis of the energy to be received.

9. The method for accommodating power according to claim 7, wherein

the second condition further comprises the energy that the consumer management apparatus can supply, the method further comprising:

a step of causing, by the control unit of the consumer management apparatus, the distributed power supply to drive the distributed power supply in a state in which a reserve generating capacity corresponding to the energy which can be supplied is reserved; and

in response to the requesting step, a step of causing, by the control unit of the consumer management apparatus, the distributed power supply to generate power based on the energy that can be supplied.

10. The method for accommodating power according to claim 9,

wherein when, in the supplying step, the information control unit detects that the consumer management apparatus driving the distributed power supply in a state in which a reserve generating capacity corresponding to the energy which can be supplied is reserved has satisfied the first condition, the information control unit supplies power preferentially to the consumer management apparatus.

11. The method for accommodating power according to claim 7, wherein the power control unit is a power router capable of outputting received power to one or more specified destinations in specified amounts.

12. The method for accommodating power according to claim 9, wherein

the plurality of power routers are connected to one another so that power can be transmitted or received therebetween,

in the detecting step, the information control unit detects that the first consumer management apparatus capable of transmitting or receiving power to or from a first power router has satisfied the first condition, and

in the requesting step, the information control unit determines the second consumer control apparatus that can transmit or receive power to or from a second power router and satisfies the second condition, calculates a power transmission path from the second power router to the first power router, and notifies the power routers on the power transmission path of the power transmission path, and

in the supplying step, the power routers transmit power via the power transmission path.

13. A non-transitory computer-readable medium storing a program for causing a computer to perform the method according to claim 7.
