The CO ₂ emission basic unit indicating the CO ₂ emission amount per kWh of the electric power generated by the grid power source is referred to as “grid power source CO ₂ emission basic unit”.

The grid power source CO ₂ emission basic unit UP is calculated by the equation (1). The natural energy power generation facility CO ₂ emission basic unit UPP is calculated by equation (2). In this example, the grid power source is hydroelectric power generation, nuclear power generation, and thermal power generation (coal), and the natural energy is solar power generation and wind power generation.

UP = (UHydro × PHydro + UNuclear × PNuclear + UCoal × PCoal) / TP (1)

The device operation pattern determination unit 5 includes the total CO ₂ emission basic unit from 0:00 to 24:00 on the day calculated by the CO ₂ emission basic unit calculation unit 4, the external device information stored in the device usage information storage unit 3, and Based on the above, the operation pattern of each external device of the external device 11 is determined. As described above, an example of an operation pattern when eight external devices are set as the external devices 1 to n of the external device 11 is shown in FIG. As shown in FIG. 4, the operation time of each external device 1 to n of the external device 11 is determined as an operation pattern. For example, the operation time of 19:30 to 20:00 is determined as the operation pattern of the washing machine, and the operation time of 20:40 to 21:00 is determined as the operation pattern of the dishwasher.

The device operation pattern determination unit 5 determines the operation patterns of the external devices 1 to n of the external device 11 based on the following rules. Among the external devices 1 to n of the external device 11, an external device that does not specify a use time zone is set to an operation pattern that operates in a time zone in which the total CO ₂ emission basic unit is small, while an external device that can be used intermittently The equipment is operated in a time zone in which the total CO ₂ emission basic unit is small, and the operation is temporarily stopped in a time zone in which the CO ₂ basic unit is large, and the total CO ₂ expressed by the equation (4) is used. The operation pattern that minimizes the emission amount Rtotal is determined. The total CO ₂ emission amount Rtotal is the total emission amount of CO ₂ emitted during power generation by the natural energy power generation facility and the grid power source, using the power consumed by all the external devices 1 to n of the external device 11.

Rtotal = UP '(19-20) x P (washing machine) x T (washing machine) + UP' (20-21) x P (dishwasher) x T (dishwasher) + ...

Output a control signal. The device control command device 10 controls the operation of the external devices 1 to n of the external device 11 based on the control signal output from the control signal output unit 6.

According to this embodiment, by controlling the operation of the external device 11 based on the operation pattern total CO ₂ emissions was determined to be the minimum, reducing the emissions of CO ₂ emitted during power generation Can do.

In this embodiment, when determining the operation pattern, since the pattern is determined so that the total CO ₂ emission amount is minimized, the use of external devices is concentrated at night when the total CO ₂ emission basic unit is small, Natural energy generated during the day may not be consumed.

As a countermeasure against this, the operation pattern determination unit 5 can consume the natural energy power generation amount, and the natural energy power generation amount can be consumed by determining the operation pattern so that the total CO ₂ emission amount is minimized.

(Fifth embodiment)
The configuration of the fifth embodiment of the CO ₂ reduction control apparatus according to the present invention will be described with reference to FIG. FIG. 9 is a block diagram showing the configuration of the CO ₂ reduction control device. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The surplus power generation detection unit 18 is based on the predicted value of the natural energy power generation amount predicted by the natural energy power generation amount prediction unit 1 and the current value of the current natural energy power generation amount generated by the natural energy power generation facility 14. Of the power generated by the natural energy power generation facility 14, when surplus power is generated that is not used up by the external device 11, it is detected.

  That is, the surplus power generation detection unit 18 has a current value of the current natural energy power generation amount generated by the natural energy power generation facility 14 larger than the predicted value of the natural energy power generation amount predicted by the natural energy power generation amount prediction unit 1. In this case, generation of surplus power is detected by determining that surplus power that has not been used up by the external device 11 has been generated from the power generated by the natural energy power generation facility 14.

  When the surplus power generation detection unit 18 detects that surplus power has been generated, a surplus power generation signal is output to the storage signal output unit 20. The power storage signal output unit 20 to which the surplus power generation signal is input outputs a power storage signal for instructing power storage to the power storage device 22.

According to the present embodiment, in addition to the effects of the first embodiment, when surplus power is generated by the natural energy power generation facility, the influence of the power temporarily on the grid (power supply network) can be suppressed. For example, the amount of power generated by the natural energy power generation facility that is generated excessively during the daytime or windy hours is stored in the power storage means 22, and the grid is used in the nighttime when the total CO ₂ emission intensity is high or in bad weather. By discharging to the (power supply network), the total CO ₂ emission can be reduced.

As described above, the same effect can be obtained even if the low CO ₂ emission unit generation detection unit 23 is provided.

Here, the low CO ₂ emission basic unit generation detection unit 23 determines that the total CO ₂ emission basic unit calculated by the CO ₂ emission basic unit calculation unit 4 is the lower limit value of the total CO ₂ emission basic unit set in advance ( Hereinafter, it is referred to as “total CO ₂ emission basic unit lower limit value.”) When it is detected that the following is reached, a low CO ₂ emission basic unit generation signal is output to the storage signal output unit 20. The power storage signal output unit 20 to which the low CO ₂ emission basic unit generation signal is input outputs a power storage signal that instructs the power storage means 22 to store power. The power storage device 22 stores the power generated by the energy power generation facility 14.
