Abstract

A power management method comprises a step A of transmitting a first message from a power management server to a local control apparatus according to a first protocol. The power management server manages a facility connected to a power grid. The local control apparatus is provided in the facility. A communication between the local control apparatus and an equipment provided in the facility is performed according to a second protocol different from the first protocol. The step A includes a step of transmitting the first message in a manner capable of identifying a control for the local control apparatus and a control for a target equipment which is the equipment designated by the power management server.

Claims

1. A power management method comprising:

a step A of transmitting a first message from a power management server to a local control apparatus according to a first protocol, the power management server managing a facility connected to a power grid, the local control apparatus provided in the facility, wherein

a communication between the local control apparatus and an equipment provided in the facility is performed according to a second protocol different from the first protocol, and

the step A includes a step of transmitting the first message in a manner capable of identifying a control for the local control apparatus and a control for a target equipment which is the equipment designated by the power management server.

2. The power management method according to claim 1, wherein

the first message is an instruction to request setting of an operation state of the target equipment,

the power management method comprises:

a step C of selecting by the local control apparatus, one or more local information elements corresponding to information elements complied with the first message, from among local information elements which the target equipment is capable of dealing with according to the second protocol; and

a step D of transmitting from the local control apparatus to the target equipment, a message including a selected local information element as an information element, as the second message.

3. The power management method according to claim 1, wherein

the first message is an instruction to request a control of a power flow from the power grid to the facility or a reverse power flow from the facility to the power grid,

the power management method comprises:

a step E of selecting one or more local information elements that realize the control of the power flow or the reverse power flow instructed by the first message, from among local information elements which the target equipment is capable of dealing with according to the second protocol; and

a step F of transmitting from the local control apparatus to the target equipment, the second message including a selected local information element.

4. The power management method according to claim 1, wherein

the first message is an instruction to request reporting of information on the target equipment,

the power management method comprises a step G of determining by the local control apparatus whether or not to inquire the target equipment about the information on the target equipment.

5. The power management method according to claim 4, wherein

the step G comprising a step of determining whether to inquire the target equipment for the information on the target equipment according to a type of the information on the target equipment.

6. The power management method according to claim 4, wherein

when determining to inquire the target equipment about the information on the target equipment, the power management method comprises:

a step H of selecting one or more local information elements corresponding to information element complied with the first message, from among local information elements which the target equipment is capable of dealing with according to the second protocol;

a step I of transmitting from the local control apparatus to the target equipment, the second message including a selected local information element; and

a step J of transmitting from the local control apparatus to the power management server, a first message response including an information element based on the information on the target equipment obtained from the target equipment by transmission of the second message.

7. The power management method according to claim 4, wherein

when determining to not inquire the target equipment about the information on the target equipment, the power management method comprises:

a step K of transmitting from the local control apparatus to the power management server, a first massage response including an information element based on the information on the target equipment managed by the local control apparatus.

8. The power management method according to claim 1, comprising:

a step L of managing by the local control apparatus, a correspondence relationship between a local information element which the target equipment is capable of dealing with and an information element complied with the first message.

9. The power management method according to claim 1, comprising:

a step M of determining by the power management server, to instruct one of the control for the local control apparatus and the control for the target equipment, based on an execution time length during which a control of a power flow from the power grid to the facility or a reverse power flow from the facility to the power grid is performed.

10. The power management method according to claim 1, comprising:

a step N of determining by the power management server, to instruct one of the control for the local control apparatus and the control for the target equipment, based on a waiting time length until a timing at which the control of the power flow or the reverse power flow is performed.

11. A power management server that manages a facility connected to a power grid, the power management server comprising:

a transmitter configured to transmit a first message to a local control apparatus provided in the facility according to a first protocol, wherein

a communication between the local control apparatus and an equipment provided in the facility is performed according to a second protocol different from the first protocol, and

the transmitter is configured to transmit the first message in a manner capable of identifying a control for the local control apparatus and a control for a target equipment which is the equipment designated by the power management server.

12. A local control apparatus provided in a facility connected to a power grid, the local control apparatus comprising:

a receiver configured to receive a first message according to a first protocol from a power management server that manages the facility; and

a transmitter configured to transmit a second message according to a second protocol different from the first protocol to an equipment provided in the facility, wherein

the receiver is configured to receive the first message in a manner capable of identifying a control for the local control apparatus and a control for a target equipment which is the equipment designated by the power management server.

13. A power management system comprising:

a power management server that manages a facility connected to a power grid; and

a local control apparatus provided in the facility, wherein

the power management server includes a first transmitter configured to transmit a first message to the local control apparatus according to a first protocol,

the local control apparatus includes a transmitter configured to transmit a second message to an equipment provided in the facility according to a second protocol different from the first protocol, and

the first transmitter is configured to transmit the first message in a manner capable of identifying a control for the local control apparatus and a control for a target equipment which is the equipment designated by the power management server.
