The detailed operation of the step S2 of acquiring the preference time of the consumer for each device will be described with reference to FIG.

First, the power user selects whether or not to directly input the power consumption preferred time zone information for each electric appliance (step S2-1).

If the power user has selected to directly input the power consumption preference time zone information for each electric device at step S2-1, the process goes to step S2-2, where the electric power user operates the user interface unit 11 directly to select the electric power consumption preferred time zone Information is directly input (step S2-2).

If the power user has selected not to directly input the power consumption preference time zone information for each electric device at step S2-1, the process proceeds to step S2-3, where the preference time input processing unit 12 of the general power consumption management device 10 determines Based on the electric power consumption pattern information of each electric device including the most used electric power consumption time period among the electric power consumption information for each electric device obtained in the power consumption information obtaining step S1, Obtain information.

Thus, the user preference time zone for each electric device is determined (step S2-4).

Referring back to FIG.

 The scheduling processing unit 13 of the general power consumption management apparatus 10 calculates the load amount of the electric equipments to be managed according to the time period ), A peak load which is a maximum value during a day in total, an electric charge corresponding to a total use electric power of electric equipment to be managed for 24 hours (day), a difference between a desired use time (preferred time) To each of the comfort values is multiplied by the respective contribution variable, which is the weight of each of the adjustable peak load, the electric charge and the comfort, so that the sum is minimized.

In this schedule generation step S3, the operation of the scheduling processing unit 13 may be said to generate a time schedule such that the objective function (control target) represented by the equation is minimized as in the above-mentioned equation (1).

The detailed steps of this schedule creation step (S3) will be described with reference to FIG.

First, the scheduling processing unit 13 sets an objective function as a management objective for the whole of the electrical equipment to be managed for 24 hours a day (S3-1). The objective function can be expressed as Equation (1).

Next, the scheduling processing unit 13 generates a constraint expression for each electric device (S3-2).

Here, the constraint condition is a condition (condition) to be considered for each electric device as described above. In the case where the electric device is a washing machine, condition information can be set to be used only once during a certain time period per day. And the range of power consumption when the temperature control knob is adjusted to the maximum temperature, in the form of a formula so that the microprocessor central processing unit can process the contents to be. In the constraint expression, an initial value of an electric device condition preset in the manufacture of the power consumption management device of the present invention or a change value of an electric device condition set by a power user through the user interface 11 is converted into a formula Lt; / RTI >

Next, the scheduling processor 13 generates a usage time schedule for the electric devices for 24 hours on the basis of the generated constraints (S3-3).

Next, in step S3-4, the scheduling processing unit 13 finds a usage time schedule in which the objective function has a minimum value in consideration of the peak load, the electric charge, and the comfort for the usage time schedule generated in step S3-3.

For example, the time planning for the peak load is calculated by using the time of use of the electric equipment to reduce the load in the time zone in which the total electric power consumption (load) Create a plan for the use of electrical equipment to create a plan and increase the load of other time zones.

The time schedule considering the electricity bill is to make a plan of use time of the electric equipment so that the electric equipment can be used at a cheap time when the electricity bill is available for 24 hours a day.

In addition, the preparation of the time schedule in consideration of the comfort is to prepare the usage time plan for each electric device as close as possible to the preference time of each electric device.

Therefore, the usage time plan in which the objective function becomes the minimum value is searched.

The usage time planning in which the objective function found in step S3-4 becomes the minimum value is selected as the usage time planning of the managed electric appliances to be applied later (S3-5).

As described above, if the electric power use time plan of the electric device is prepared so as to benefit the electric power consumption in the home in terms of both the electric power supplier and the electric power user as described above, according to a preferred aspect of the present invention, The process by which weights can be adjusted to the extent that the power user satisfies the three factors can be provided as follows.

That is, after the execution of the electric power usage of the electric device according to the time schedule generated in the schedule generation step S3, a contribution variable adjustment step capable of adjusting the corresponding contribution variable for at least one of the peak load, the electric charge and the comfort Can be executed.

If the peak load or the amount of electric power or comfort differs from the expected degree, the corresponding contribution variable is adjusted for at least one of the peak load, the electric charge and the comfort according to the input of the electric power consumer in the adjustment of the contribution variable .

In this case, when the contribution variables of the three management opposing elements of the contribution variable are λ1, λ2, and λ3, for example, λ1 + λ2 + λ3 = 100, the values of λ1, λ2, The remaining two values can be adjusted in such a manner that they are relatively reduced.

It is determined whether the peak load is a desired level (step S4-1). After the power management is performed in accordance with the time schedule established as described above for 24 hours a day, the power user is informed to the power user through the user interface unit 11 of the general power consumption management device 10, (Load) used to determine if the load weight of the most power-consuming (peak load) time period needs adjustment.

If the power user determines that the weight for the peak load needs to be adjusted in step S4-1 (in the case of 'No' in step S4-1), the contribution variable for the peak load ) < / RTI > That is, the adjustment value of the contribution variable (weight)? 1 to the peak load inputted by the power user through the user interface unit 11 is set as the setting value of the contribution variable (weight)? 1 for the new peak load The scheduling processor 13 of the controller 10 rewrites the usage time plan of the electric devices that reflects the new attribution variable (weight) lambda 1 (S5-1).

If the power user determines that the weight for the peak load is unnecessary in step S4-1 (YES in step S4-1), the process proceeds to step S4-2.

Next, in step S4-2, it is confirmed whether or not it is a desired level of electricity. This is because the power management is performed in accordance with the time schedule established as described above for 24 hours a day, and then the electric power is supplied to the electric power user through the user interface unit 11 of the general power consumption management device 10, It can be accomplished by displaying the electricity bill so as to determine whether the electricity bill weights need adjustment.

If the power user determines in step S4-2 that adjustment is required on the weight for the electric charge (in the case of 'No' in step S4-2), the contribution variable (weight)? 2 . ≪ / RTI > That is, the adjustment value of the contribution variable (weight)? 2 to the electric charge input by the power user through the user interface unit 11 is set as the setting value of the contribution variable (weight)? 2 for the new electric charge, The scheduling processing unit 13 of the control unit 13 rewrites the use time schedule of the electric devices that reflect the new attribution variable (weight)? 2 (S5-2).

Next, in step S4-3, confirm that the desired level of comfort is achieved. After the power management is performed in accordance with the time schedule established as described above for 24 hours a day, the power user is informed to the power user through the user interface unit 11 of the general power consumption management device 10, To determine the need for adjustment to the comfort weights of the time zone with the greatest comfort complaint value (i.e., the difference between the desired time and actual usage time).

If the power user determines that adjustment of the weight for comfort is required at step S4-3 (in the case of 'No' at step S4-3), the contribution variable (weight)? 3 . ≪ / RTI > That is, the adjustment value of the contribution variable (weight)? 3 for the comfort input by the power user through the user interface unit 11 is set as the setting value of the contribution variable (weight)? 3 for the new comfort, The scheduling processor 13 of the controller 3 rewrites the usage time plan of the electric devices that reflects the new attribution variable (weight)? 3 (S5-3).

As described above, the power consumption management apparatus for managing the power consumption in the household according to the present invention includes the overall power consumption management apparatus, wherein the overall power consumption management apparatus includes a user interface unit, a preference time input processing unit, The power user can input information including a selection of comfort indicating the power user's satisfaction with the peak load, the electric charge, and the usage time of each electric device,
