  In addition, the control unit 22 creates an image according to the information about the target value related to the profit from the power generation of the distributed power supply 15 and the power information acquired by the acquisition unit 21, and causes the display device 11 to display the generated image. The control unit 22 can be configured by, for example, a microcomputer or a processor.

  Next, a specific example of an image created by the control unit 22 according to the present embodiment will be described.

  FIG. 3 is a diagram illustrating an example of an image created by the control unit 22.

  As shown in FIG. 3, the image generated by the control unit 22 includes a power generation amount 31 of the distributed power source 15, a consumption amount 32 and a power sale amount 33 in the customer facility of the power supplied from the distributed power source 15 to the load device 17. include. In addition, the image created by the control unit 22 includes a target value (target amount) 34 relating to profits from power generation by the distributed power supply 15, profits 35 obtained by power generation by the distributed power supply 15, and power generation by the distributed power supply 15 with respect to the target price. The percentage of profits obtained 36 is included.

  The control unit 22 calculates the profit obtained by the power generation of the distributed power supply 15 as follows. That is, as shown in FIG. 4, the total power generation amount of the distributed power source 15 in a certain period is the sum of the power consumed by the customer facility and the power sales amount of the power supplied by the distributed power source 15 in that period. is there. As described above, based on the power information acquired by the acquisition unit 21, the control unit 22 consumes the total power generation amount of the distributed power source 15 and the power supplied by the distributed power source 15 at a consumer facility for a certain period. The amount and power sales can be grasped.

  Here, the user can arbitrarily set the fixed period. The fixed period may be, for example, a cumulative period from when the operation of the distributed power supply 15 is started to the present, or may be a specific period such as one day or one year.

  And the control part 22 calculates | requires the electricity bill equivalent to consumption based on the consumption in the consumer facility of the electric power supplied by the distributed power supply 15, and the rule regarding calculation of the electricity bill applied to the consumer facility. calculate. The control unit 22 calculates a power sale fee corresponding to the power sale amount based on the power sale amount and a predetermined power sale unit price. Then, the control unit 22 calculates, as a profit obtained by the power generation of the distributed power supply 15, an electric charge corresponding to the consumption amount and a cumulative value of the power sale fee corresponding to the power sale amount for each fixed period.

  Regulations relating to the calculation of electricity charges applied to customer facilities and charge information on the unit price of electricity sales are input in advance to the power management apparatus 12 via the display device 11 equipped with a touch panel, for example, and stored in the storage device 25. ing. Further, these fee information may be input from the system EMS 60 to the power management apparatus 12 via the external network 70, for example. In addition, when the acquisition unit 21 has a function of communicating with another terminal, these pieces of information may be input via the other terminal.

  As described above, the image showing the target amount of profit obtained by the power generation of the distributed power source 15 and the actual profit obtained, which is a great concern for the user, is further aroused by the user. be able to.

  FIG. 5 is a diagram illustrating another example of an image created by the control unit 22. In FIG. 5, the same components as those in FIG.

  As shown in FIG. 5, the image created by the control unit 22 includes a target line indicating the target amount of money, and a cumulative value of profits obtained by power generation of the distributed power source 15 every fixed period (for example, every month). Is further included.

  By showing a graph showing the target amount and the cumulative value of profit obtained from the power generation of the distributed power source 15, the user can more intuitively grasp the degree of increase in profit for a certain period or the degree of achievement of the target amount. It becomes easy.

  FIG. 6 is a diagram illustrating another example of an image created by the control unit 22. In FIG. 6, the same components as those in FIG.

  In the example illustrated in FIG. 6, the control unit 22 creates an image indicating the target amount and the profit obtained by the power generation of the distributed power source 15 by using an object. Specifically, the image generated by the control unit 22 corresponds to the target population 38 of the city corresponding to the target amount of money, the population 39 of the city corresponding to the profit obtained by the power generation of the distributed power source 15, and the power generation amount. Building 40 to be included. Then, the control unit 22 creates an image such that the town develops radially as the power generation profit increases.

  In this way, by expressing the target amount, the profit obtained by the power generation of the distributed power supply 15 and the like by the object, the user can understand more intuitively.

  FIG. 7 is a diagram illustrating another example of an image created by the control unit 22. In FIG. 7, the same components as those in FIG.

  As shown in FIG. 7, the image created by the control unit 22 includes a target achievement time point (target target achievement date 41) that is a predicted value when the profit obtained by the power generation of the distributed power supply 15 reaches the target amount. Is further included. The target achievement time point can be predicted from, for example, the profit obtained by the power generation of the distributed power source 15 for each fixed period in the storage device 25 and the increase in profit for each fixed period or the past actual value. it can.

  Thus, by displaying the target achievement time point, the user's interest can be further aroused. In particular, by displaying the target achievement date, it is possible to know the number of days required until the goal is achieved, thereby further arousing the user's interest.

  The amount of power generated by the distributed power supply 15 may gradually decrease due to deterioration over time. Therefore, the control unit 22 may predict the target achievement time point in consideration of the temporal deterioration of the distributed power supply 15. For example, the control unit 22 can predict the future power generation amount of the distributed power supply 15 based on the deterioration coefficient obtained by quantifying the degree of decrease in the power generation amount due to deterioration over time, and predict the target achievement point based on this prediction. it can.

  For example, it is assumed that the deterioration coefficient is 0% at the initial stage of installation, 0.5% after one year from installation, and 5% after ten years from installation (deteriorates by 0.5% every year). In this case, assuming that the maximum power generation amount of the distributed power source 15 at the initial installation is 1.0 (3.0 kW), the maximum power generation amount of the distributed power source 15 becomes 0.95 (2.85 kW) after 10 years. Therefore, for example, if it is assumed that there is no deterioration, and if it is predicted that the profit will reach the target amount in 10 years, considering the deterioration, the target achievement point will be delayed by about 2.5% (about 3 months) Become.

  Information on the degradation of the distributed power source 15 such as the degradation coefficient can be obtained based on a manufacturer's verification experiment. Such information may be input in advance to the power management apparatus 12 via the display device 11 including a touch panel, or may be input from the system EMS 60 via the external network 70 in advance.

  In this way, by predicting the target achievement point in consideration of the deterioration with time of the distributed power supply 15, it is possible to improve the prediction accuracy at the target achievement point.

  Next, an installation example and an operation example of the power management apparatus 12 according to the present embodiment will be described.
