Abstract

A received electric power reduction information calculation apparatus (corresponding to an example of a received energy reduction information calculation apparatus) has an energy predictor and a reduction information calculator. The energy predictor predicts a prediction amount of at least one of energy supply and energy consumption in a future prescribed time period with respect to at least one of an energy-supplying equipment and an energy-consuming equipment, based on a request for reduction of the received energy. The reduction information calculator calculates the reduction amount of the received energy associated with the prediction amount, based on an energy fee reflected from an expected fee of incentive with respect to the reduction request of the received energy.

Claims

1. A received energy reduction information calculation apparatus comprising:

an energy predictor that predicts a prediction amount of at least one of energy supply and energy consumption in a future prescribed time period with respect to at least one of an energy-supplying equipment and an energy-consuming equipment, based on a request for reduction of the received energy; and

a reduction information calculator that calculates the reduction amount of the received energy associated with the prediction amount, based on an energy fee reflected from an expected fee of incentive with respect to the reduction request of the received energy.

2. The received energy reduction information calculation apparatus according to claim 1, further comprising:

an incentive unit price setter that sets a plurality of incentive unit prices,

wherein the reduction information calculator calculates the received energy reduction amount for each incentive unit price of incentive set by the incentive unit price setter.

3. The received energy reduction information calculation apparatus according to claim 2, wherein the incentive unit price setter acquires an incentive unit price change amount and an incentive unit price upper limit value, and sets a plurality of incentive unit prices based on the incentive unit price change amount and the incentive unit price upper limit value as acquired.

4. The received energy reduction information calculation apparatus according to claim 1, further comprising:

an output equipment that displays the reduction amount of the received energy calculated by the reduction information calculator, using a graph showing a relationship between the incentive unit price and the reduction amount of the received energy.

5. The received energy reduction information calculation apparatus according to claim 4, wherein the output equipment displays, on the graph, a past-agreed amount of the incentive unit price.

6. The received energy reduction information calculation apparatus according to claim 1, further comprising:

an incentive unit price setter that acquires a past-agreed amount of the incentive unit price and sets an expected amount of the incentive unit price based on the past-agreed amount,

wherein the reduction information calculator calculates the received energy reduction amount with respect to an expected value of the incentive unit price set by the incentive unit price setter.

7. The received energy reduction information calculation apparatus according to claim 6, wherein the incentive unit price setter sets the expected amount, based on a mean value of the past-agreed amounts of the incentive unit price which were agreed in demand responses plural times in the past.

8. The received energy reduction information calculation apparatus according to claim 6, wherein the incentive unit price setter sets the expected amount, based on a minimum value of the past-agreed amounts of the incentive unit price which were agreed in demand responses plural times in the past.

9. The received energy reduction information calculation apparatus according to claim 6, wherein the incentive unit price setter sets the expected amount, based on a maximum value of the past-agreed amounts of the incentive unit price which were agreed in demand responses plural times in the past.

10. A method of calculating received energy reduction information of a received energy reduction information calculation apparatus, the method comprising:

an energy predicting step for predicting a prediction amount of at least one of energy supply and energy consumption in a future prescribed time period with respect to at least one of an energy-supplying equipment and an energy-consuming equipment, based on a reduction request for reduction of the received energy; and

a reduction information calculation step for calculating the reduction amount of the received energy associated with the prediction amount, based on an energy fee reflected from an expected fee of incentive with respect to the reduction request of the received energy.

11. A non-temporary computer-readable storage medium that stores a program for a computer included in a received energy reduction information calculation apparatus, the program when executed by the computer to cause the computer to perform:

an energy predicting step of predicting a prediction amount of at least one of energy supply and energy consumption in a future prescribed time period with respect to at least one of an energy-supplying equipment and an energy-consuming equipment, based on a reduction request for reduction of the received energy; and

a reduction information calculation step of calculating the reduction amount of the received energy associated with the prediction amount, based on an energy fee reflected from an expected fee of incentive with respect to the reduction request of the received energy.
