Abstract

Disclosed herein is an electric power management apparatus including: an electric power measurement block configured to measure an electric power consumption amount of an electric power consumer; and an electric power comparison block configured to make a comparison between an electric power consumption amount measured by the electric power measurement block and an electric power demand forecast amount indicative of a forecast amount of an electric power demand of the electric power consumer.

Claims

1. An electric power management apparatus comprising:

an electric power measurement block configured to measure an electric power consumption amount of electric devices used by an electric power consumer;

a demand forecast input block configured to receive input of a first electric power demand forecast amount from the electric power consumer for an input target period;

an electric power demand forecast block configured to calculate another electric power demand forecast amount based on a rate of change of the electric power consumption amount until the input target period; and

an electric power comparison block configured to make a comparison between the first electric power demand forecast amount and the other electric power demand forecast amount.

2. The electric power management apparatus according to claim 1, wherein the input target period is of a transaction target day on which electric power is delivered to the electric devices used by the electric power consumer.

3. The electric power management apparatus according to claim 1, further comprising a return processing block configured to determine a profit to be returned to the electric power consumer based on the comparison of the first electric power demand forecast amount and the other electric power demand forecast amount.

4. The electric power management apparatus according to claim 1, wherein the other electric power demand forecast amount is based on the rate of change of the electric power consumption amount in a transaction target day on which electric power is delivered to the electric devices until the input target period.

5. The electric power management apparatus according to claim 1, wherein the electric power demand forecast block is configured to compute the other electric power demand forecast amount by use of a predetermined learning algorithm.

6. The electric power management apparatus according to claim 1, wherein the demand forecast input block is configured to receive input of numeric values of the first electric power demand forecast amount for each of one or more predetermined sections making up the input target period, and

wherein the electric power comparison block is configured to make a comparison between the first electric power demand forecast amount entered by the electric power consumer for each of the one or more predetermined sections and the other electric power demand forecast amount.

7. The electric power management apparatus according to claim 1, further comprising a notification block configured to notify the electric power consumer of a comparison result obtained through the electric power comparison block.

8. The electric power management apparatus according to claim 1, wherein the first electric power demand forecast amount is obtained based on a behavior plan of the electric power consumer entered by the electric power consumer through the input block.

9. An electric power management method comprising:

in an electric power management apparatus;

measuring an electric power consumption amount of electric devices used by an electric power consumer;

receiving input of a first electric power demand forecast amount from the electric power consumer for an input target period;

calculating another electric power demand forecast amount based on a rate of change of the electric power consumption amount until the input target period; and

comparing the first electric power demand forecast amount and the other electric power demand forecast amount.
