Abstract

An HEMS 700 provided in a consumer having independently operable power supply means (PV 100 , storage battery 200 , PCS 400 and the like) and at least one load 300 , for controlling the power supply means and the load 300 , determines an during-independent-operation schedule that is an operation schedule of the load during the independent operation on the basis of a period when the independent operation is performed, a power supply status of the power supply means, and a status of the load 300.

First claim

The invention claimed is:

1. A control device for use in a consumer, the consumer connected to a power system and having a power supply which is operable independently of the power system and at least one load, for controlling the power supply and the at least one load, comprising:
an operation schedule determination unit that determines a during-independent-operation schedule that is an operation schedule of the at least one load during an independent operation in which the power system does not supply power,
wherein the operation schedule determination unit determines the during-independent-operation schedule, on the basis of a planned power outage period in which the independent operation is performed, a power supply status of the power supply, and a status of the at least one load.

2. The control device according to claim 1 , wherein the operation schedule determination unit determines the during-independent-operation schedule at a start time of the independent operation or during the independent operation.

3. The control device according to claim 2 , wherein the operation schedule determination unit determines the during-independent-operation schedule, on the basis of the period when the independent operation is performed, a power supply status of the power supply before determining the during-independent-operation schedule, and a status of the at least one load before determining the during-independent-operation schedule.

4. The control device according to claim 1 , further comprising:
an acquisition unit that acquires a setting of a power supply priority to the at least one load,
wherein the operation schedule determination unit determines the during-independent-operation schedule further on the basis of the setting.

5. The control device according to claim 1 , further comprising:
a power saving control unit that performs a power saving control for reducing power consumption of each load during the independent operation,
wherein the operation schedule determination unit determines the during-independent-operation schedule further on the basis of the power saving control.

6. The control device according to claim 1 , further comprising:
a power leveling control unit that performs a power leveling control for leveling out a total power consumption of the at least one load during the independent operation,
wherein the operation schedule determination unit determines the during-independent-operation schedule further on the basis of the power leveling control.

7. The control device according to claim 1 , further comprising:
an operation schedule change unit that changes at least a part of the determined during-independent-operation schedule, on the basis of at least one of the power supply status of the power supply during the independent operation, the status of the at least one load during the independent operation, or a status of a user during the independent operation.

8. A power control system for use in a consumer, the consumer connected to a power system and having a power supply which is operable independently of the power system and at least one load, and having the control device according to claim 1 .

9. The control device according to claim 1 , further comprising an operation schedule change unit that changes at least a part of the during-independent-operation schedule during the independent operation on the basis of the power supply status of the power supply during the independent operation and the status of the at least one load during the independent operation.

10. A power control method comprising:
a determination step of, by a control device, which is provided in a consumer connected to a power system and having a power supply which is operable independently of the power system and at least one load, for controlling the power supply means and the at least one load, determining a during-independent-operation schedule that is an operation schedule of the at least one load during an independent operation in which the power system does not supply power,
wherein in the determination step, the during-independent-operation schedule is determined, on the basis of a planned power outage period in which the independent operation is performed, a power supply status of the power supply, and a status of the at least one load.
