Abstract

An energy management device includes a measurement manager and a communicator. The measurement manager manages energy information based on a physical quantity measured from at least one measurement object belonging to each of a plurality of energy types in a customer. The communicator communicates the energy information of each of the energy types to another device over a network.

Claims

1. An energy management device comprising:

a measurement manager to manage energy information based on a physical quantity measured from at least one measurement object belonging to each of a plurality of energy types in a customer; and

a communicator to communicate the energy information of each of the energy types to another device over a network.

2. The energy management device according to claim 1, wherein

the energy management device is disposed on a customer side, and

said other device is disposed on a public service company side.

3. The energy management device according to claim 1, further comprising

a measurer to measure a physical quantity from a first measurement object, wherein

the measurement manager acquires energy information on an energy type relating to the first measurement object based on the measurer.

4. The energy management device according to claim 1, comprising

a control manager to manage control relating to at least one of electric power consumption, electric power generation, and electric power storage, wherein

the control manager transmits instruction information on the control to another energy management device that controls at least one of an electric power consuming device, a generator, and an electric accumulator.

5. The energy management device according to claim 4, wherein the control manager performs at least one of demand management and reverse power flow management with respect to electric power or electric energy on an electric power system.

6. The energy management device according to claim 4, wherein

an owner of the energy management device is a first owner, and

an owner of said other energy management device is a second owner different from the first owner.

7. The energy management device according to claim 1, comprising

a control manager to receive instruction information on control of at least one of electric power consumption, electric power generation, and electric power storage from said other energy management device, and to control at least one of an electric power consuming device, a generator, and an electric accumulator based on the instruction information.

8. The energy management device according to claim 7, wherein

an owner of said other energy management device is the first owner, and

an owner of the energy management device is a second owner different from the first owner.

9. The energy management device according to claim 1, wherein

the measurement manager receives energy information associated with the energy type from said other energy management device,

an owner of the energy management device is a first owner, and

an owner of said other energy management device is a second owner different from the first owner.

10. The energy management device according to claim 1, wherein

the measurement manager associates the energy information with the energy type and transmits the energy information to another energy management device,

an owner of said other energy management device is a first owner, and

an owner of the energy management device is a second owner different from the first owner.

11. The energy management device according to claim 6, wherein the first owner is a public service company, and the second owner is a customer, or an owner or a developer of a facility.

12. The energy management device according to claim 1, wherein

the energy type includes

at least categories of electric power and energies other than electric power, or

at least categories of electric power consumption, electric power storage, and electric power generation, or

at least categories of electric power, water, and gas.

13. The energy management device according to claim 1, wherein

the energy management device is a server device disposed on a public service company side,

the measurement manager acquires the energy information for each energy type from an energy management device disposed on a customer side over a network, and

the server device manages energy of each of the energy types on the customer side based on energy information of each of the energy types.

14. The energy management device according to claim 13, wherein

a first energy management device and a second energy management device are disposed on a customer side,

an owner of the server device and the first energy management device is a first owner, and an owner of the second energy management device is a second owner, the energy management device further comprising

a configuration manager to manage whether to permit connection from the server device to the second energy management device, wherein

the measurement manager collects energy information of each of the energy types from the second energy management device if connection to the second energy management device is permitted, or from the first energy management device if not permitted.

15. The energy management device according to claim 14, wherein

a control manager of the server device controls the second energy management device if connection to the second energy management device is permitted, or controls the first energy management device to manage energy of each of the energy types on the customer side if not permitted.

16. An energy management system comprising:

a first energy management device;

a plurality of second energy management devices each having a measurer to measure a physical quantity from at least one measurement object out of an electric power consuming device, a generator, and an electric accumulator; and

an aggregating device to receive measurement information on the measurement objects from the second energy management device, and to compress the measurement information according to device types of the measurement objects and transmit the compressed measurement information to the first energy management device.

17. The energy management system according to claim 16, further comprising

a data storage, wherein

one of the plurality of second energy management devices measures physical quantities from a measurement object relating to an energy other than electric power, and stores the measured information in the data storage without transmitting the measured information to the first energy management device.

18. The energy management system according to claim 16, further comprising

a server device disposed on a public service company side, wherein

the first energy management device is disposed on a customer side,

the server device acquires energy information based on physical quantities measured by the second energy management device for each of the device types, through the first energy management device, and manages control of at least one of electric power consumption, electric power generation, and electric power storage of the customer, based on the acquired energy information.

19. The energy management system according to claim 16, wherein

the second energy management device is installed in the measurement object, a submeter to measure the measurement object, a master meter to manage the submeter, or a controller to control the measurement object.

20. An energy management method comprising:

managing energy information based on a physical quantity measured from at least one measurement object belonging to each of a plurality of energy types in a customer; and

communicating the energy information of each of the energy types to another device over a network.
