Abstract

An energy management system having a fuel cell apparatus ( 150 ) as a power generator that generates power using fuel, and an EMS ( 200 ) that communicates with the fuel cell apparatus ( 150 ). The EMS ( 200 ) receives messages that indicate a type of the fuel cell apparatus ( 150 ), from the fuel cell apparatus ( 150 ).

First claim

The invention claimed is:

1. A management system comprising a plurality of apparatuses arranged in a network:
a power generation apparatus which generates power using fuel; and
a control apparatus which communicates with the power generation apparatus over the network, wherein the control apparatus
receives a first message from the power generation apparatus, via the network, wherein the first message indicates that the power generation apparatus is capable of transmitting a type or status of the power generation apparatus,
after receiving the first message, transmits a second message to the power generation apparatus, via the network, wherein the second message requests the power generation apparatus to indicate the type or status of the power generation apparatus, and,
after transmitting the second message, receives a third message from the power generation apparatus, via the network, wherein the third message indicates the type or status of the power generation apparatus.

2. The management system according to claim 1 , wherein the type of the power generation apparatus includes information designating either one of a fuel cell and a gas engine-type power generation apparatus.

3. The management system according to claim 1 , wherein the type of the power generation apparatus includes information designating any one of a solid oxide fuel cell, a polymer electrolyte fuel cell, a phosphoric acid fuel cell, and a molten carbonate fuel cell.

4. The management system according to claim 1 , wherein the third message indicates the status of the power generation apparatus.

5. The management system according to claim 4 , wherein the status of the power generation apparatus comprises information about a planned stoppage of the power generation apparatus within a normal operation of the power generation apparatus.

6. The management system according to claim 4 , wherein the status of the power generation apparatus comprises an indication of whether or not a radiating unit of the power generation apparatus is being used.

7. A management method used in a management system having a power generation apparatus which generates power using fuel, and a control apparatus which communicates with the power generation apparatus over a network, the method comprising, by the control apparatus:
receiving a first message from the power generation apparatus, via the network, wherein the first message indicates that the power generation apparatus is capable of transmitting a type or status of the power generation apparatus,
after receiving the first message, transmitting a second message to the power generation apparatus, via the network, wherein the second message requests the power generation apparatus to indicate the type or status of the power generation apparatus, and,
after transmitting the second message, receiving a third message from the power generation apparatus, via the network, wherein the third message indicates the type or status of the power generation apparatus.

8. A control apparatus which communicates over a network with a power generation apparatus which generates power using fuel, the control apparatus comprising:
a controller which
receives a first message from the power generation apparatus, via the network, wherein the first message indicates that the power generation apparatus is capable of transmitting a type or status of the power generation apparatus,
after receiving the first message, transmits a second message to the power generation apparatus, via the network, wherein the second message requests the power generation apparatus to indicate the type or status of the power generation apparatus, and,
after transmitting the second message, receives a third message from the power generation apparatus, via the network, wherein the third message indicates the type or status of the power generation apparatus.

9. A power generation apparatus which generates power using fuel, the power generation apparatus comprising:
a controller which
transmits a first message to the control apparatus, via the network, wherein the first message indicates that the power generation apparatus is capable of transmitting a type or status of the power generation apparatus,
after transmitting the first message, receives a second message from the control apparatus, via the network, wherein the second message requests the power generation apparatus to indicate the type or status of the power generation apparatus, and,
in response to receiving the second message, transmits a third message to the control apparatus, via the network, wherein the third message indicates the type or status of the power generation apparatus.

10. The management system according to claim 5 , wherein the information about a planned stoppage indicates a time period during which the planned stoppage will occur.
