Abstract

A control device for controlling the operation of a supply and demand adjustment device that is connected to a power grid includes: detection means for detecting the state of the supply and demand adjustment device; communication means for transmitting the detection result of the detection means to an external device and receiving from the external device operation control information for controlling the operation of the supply and demand adjustment device; comprehension means for receiving and comprehending an adjustment power amount transmitted by bidirectional communication or one-way communication; and control means for, based on the adjustment power amount and the operation control information, controlling the operation of the supply and demand adjustment device.

First claim

1 . A control device that controls the operation of a supply and demand adjustment device that is connected to a power grid, comprising:
detection means that detects the state of said supply and demand adjustment device; communication means that transmits the detection result of said detection means to an external device and that receives from said external device operation control information that controls the operation of said supply and demand adjustment device; comprehension means that receives and comprehends an adjustment power amount that is transmitted by bidirectional communication or one-way communication; and control means that, based on said adjustment power amount and operation control information received by said communication means, controls the operation of said supply and demand adjustment device.

2 . The control device according to claim 1 , wherein said adjustment power amount is transmitted from an external device.

3 . The control device according to claim 1 , wherein:
said communication means receives said operation control information at predetermined intervals; and said comprehension means receives said adjustment power amount at intervals that are shorter than said predetermined spacing.

4 . The control device according to claim 1 , wherein said operation control information is generated on the basis of:
the state of said supply and demand adjustment device that is detected by said detection means; and the amount of power that is allotted to all supply and demand adjustment devices that are controlled by N (where N is a number equal to or greater than 1) of said control devices.

5 . The control device according to claim 4 , wherein:
said operation control information is the ratio of the total amount of the chargeable/dischargeable capacity in said supply and demand adjustment device and the amount of power allotted to all said supply and demand adjustment devices; and said control means determines the amount of power of each of said supply and demand adjustment device on the basis of said adjustment power amount and said ratio.

6 . The control device according to claim 1 , wherein said control means controls the operation of said supply and demand adjustment device on the basis of the state of said supply and demand adjustment device that is detected by said detection means.

7 . The control device according to claim 1 , wherein said adjustment power amount is an amount determined on the basis of power flow of an interconnection line by which said power grid is connected to another power grid, and the grid frequency of said power grid.

8 . The control device according to claim 1 , wherein said adjustment power amount that is received by said comprehension means is the same as the adjustment power amount that is received by another control device.

9 . A control device that controls the operation of a supply and demand adjustment device that is connected to a power grid, comprising:
detection means that detects the state of said supply and demand adjustment device; communication means that transmits to an external device the detection result of said detection means and that receives from said external device operation control information that controls the operation of said supply and demand adjustment device; comprehension means that receives and comprehends an adjustment power amount; and control means that, based on said adjustment power amount, operation control information that was received by said communication means and the state of said supply and demand adjustment device that was detected by said detection means, controls the operation of said supply and demand adjustment device.

10 . A control device that controls the operation of a supply and demand adjustment device that is connected to a power grid, comprising:
detection means that detects the state of said supply and demand adjustment device; communication means that transmits to an external device the detection result of said detection means and that receives from said external device operation control information that controls the operation of said supply and demand adjustment device; comprehension means that receives and comprehends an adjustment power amount that was transmitted from an external device that differs from said external device; and control means that, based on said adjustment power amount and operation control information that was received by said communication means, controls the operation of said supply and demand adjustment device.

11 . A control device that controls the operation of a supply and demand adjustment device that is connected to a power grid, comprising:
detection means that detects the state of said supply and demand adjustment device; communication means that transmits to an external device the detection result of said detection means and that receives from said external device operation control information that controls the operation of said supply and demand adjustment device; comprehension means that receives and comprehends an adjustment power amount that is determined based on the power flow of an interconnection line that connects said power grid and another power grid and based on the grid frequency of said power grid; and control means that, based on said adjustment power amount and operation control information that was received by said communication means, controls the operation of said supply and demand adjustment device.

12 . A control device that controls the operation of a supply and demand adjustment device that is connected to a power grid, comprising:
detection means that detects the state of said supply and demand adjustment device; comprehension means that receives and comprehends an adjustment power amount; communication means that transmits to an external device the detection result of said detection means and that receives from said external device correspondence relation information that indicates the correspondence relation between said adjustment power amount and an allotted amount of each supply and demand adjustment device with respect to the amount of electric power that is allotted to all supply and demand adjustment devices that are controlled by N (where N is a number equal to or greater than 2) of said control devices; and control means that uses said correspondence relation information to specify the allotted amount of said supply and demand adjustment device that corresponds to said adjustment power amount and that causes said supply and demand adjustment device to charge or discharge by said allotted amount.

13 . A control device that controls the operation of a supply and demand adjustment device that is connected to a power grid, comprising:
detection means that detects the degree of tendency for said supply and demand adjustment device to deteriorate; communication means that transmits to an external device the detection result of said detection means and that receives from said external device operation control information that controls the operation of said supply and demand adjustment device; comprehension means that receives and comprehends an adjustment power amount; and control means that, based on said adjustment power amount and operation control information that was received by said communication means, controls the operation of said supply and demand adjustment device; wherein said control means reduces the operating load of said supply and demand adjustment device in proportion to the tendency of the supply and demand adjustment device to deteriorate.

14 . The control device according to claim 9 , wherein:
said communicati
