Abstract

A power generation control device is provided with: a communication unit that receives output control information determined on the basis of a first index that relates to the output state at a power generation device group and a second index that relates to the output state at a predetermined power generation device; and a control unit that controls the output of the predetermined power generation device on the basis of the output control information.

First claim

The invention claimed is:

1. A control device comprising:
a memory storing instructions; and
at least one processor configured to execute the instructions to:
determine output control information of at least a portion of power generation devices among a plurality of power generation devices on a basis of a first index that relates to an output limitation state at a power generation device group and a second index that relates to an output limitation state at a plurality of power generation devices that belong to said power generation device group;
determine said output control information such that a difference between the output limitation state at said power generation device group in an output control time slot and the output limitation state at said power generation devices in said output control time slot decreases; and
determine said output control information to increase a range of change of a maximum-value output of said power generation devices in proportion to increase of a difference between said first index and said second index; and
transmit said output control information to corresponding said power generation devices;
wherein said output limitation state comprises at least one of:
an amount of power generation resulting from output control in the power generation device group or in the power generation device,
an amount of power generation limitation resulting from output control in the power generation device group or in the power generation device,
a maximum-value amount of power generation,
an ON/OFF state of the power generation device,
a time during which output is controlled,
an electricity sales profit that results from output control,

or
electricity sales loss that results from output control.

2. The control device according to claim 1 , wherein the at least one processor is further configured to determine said output control information according to the difference between the output limitation state at said power generation device group in an output control time slot and the output limitation state at said power generation device in said output control time slot.

3. The control device according to claim 1 , wherein the at least one processor is further configured to determine a portion of said power generation devices that use predetermined output control information from among power generation devices that belong to said power generation device group on the basis of said first index and said second index.

4. The control device according to claim 1 , wherein the at least one processor is further configured to determine said output control information in accordance with the difference between a first index that relates to the output limitation state at a power generation device group and a first index that relates to the output limitation state at a power generation device group that differs from said power generation device group.

5. The control device according to claim 1 , wherein the at least one processor is further configured to receive the power generation amount of each said power generation device in an elapsed time slot among output control time slots.

6. The control device according to claim 5 , wherein the at least one processor is further configured to determine said first index and said second index on the basis of said power generation amount of each said power generation device.

7. A control system comprising:
a plurality of power generation control devices corresponding to each of power generation devices that belong to a power generation device group, and a control device that communicates with said power generation control devices;
wherein:
said control device comprises:
a first memory storing first instructions; and
at least one first processor configured to execute the first instructions to:
determine output control information of said power generation devices on a basis of a first index that relates to an output limitation state at said power generation device group and a second index that relates to an output limitation state at each of said power generation devices;
determine said output control information such that a difference between the output limitation state at said power generation device group in an output control time slot and the output limitation state at each of said power generations devices in said output control time slot decreases; and
determine said output control information to increase a range of change of a maximum-value output of each of said power generation devices in proportion to increase of a difference between said first index and said second index; and
transmit said output control information to corresponding said power generation control devices; and

said power generation control devices each comprise:
a second memory storing second instructions; and
at least one second processor configured to execute the second instructions to:
receive said output control information; and
control output of corresponding said power generation device on the basis of received output control information;

wherein said output limitation state comprises at least one of:
an amount of power generation resulting from output control in the power generation device group or in the power generation device,
an amount of power generation limitation resulting from output control in the power generation device group or in the power generation device,
a maximum-value amount of power generation,
an ON/OFF state of the power generation device,
a time during which output is controlled,
an electricity sales profit that results from output control,

or
electricity sales loss that results from output control.

8. A control method comprising steps of:
determining output control information of at least a portion of power generation devices among a plurality of power generation devices on a basis of a first index that relates to an output limitation state at a power generation device group and a second index that relates to an output limitation state at said plurality of power generation devices that belong to said power generation device group;
determining said output control information such that a difference between the output limitation state at said power generation device group in an output control time slot and the output limitation state at said power generation devices in said output control time slot decreases; and
determine said output control information to increase a range of change of a maximum-value output of said power generation devices in proportion to increase of a difference between said first index and said second index; and
transmitting said output control information to corresponding said power generation devices;
wherein said output limitation state comprises at least one of:
an amount of power generation resulting from output control in the power generation device group or in the power generation device,
an amount of power generation limitation resulting from output control in the power generation device group or in the power generation device,
a maximum-value amount of power generation,
an ON/OFF state of the power generation device,
a time during which output is controlled,
an electricity sales profit that results from output control,

or
electricity sales loss that results from output control.
