  The control device 20 is connected to a network 30 such as the Internet, and can communicate with a terminal device 32 that can be connected to the network 30. In the present embodiment, the terminal device 32 can remotely control the ratio of power storage and power sale that can be set on the operation display panel 24. That is, by transmitting information indicating the ratio of power storage and power sale from the terminal device 32, the information is input to the control device 20 via the network 30, so that the control device 20 responds to the transmitted rate. Thus, storage of electricity to the storage battery 16 and sale of electricity to the electric power company are controlled.

  Further, the common unit 27 of the apartment house 12 has the same configuration as each dwelling unit 18. That is, as shown in FIG. 2, the common unit 27 is provided with a control device 21 that controls the flow of power in the common unit 27, and the control device 21 includes the solar power generation device 14, the storage battery 17, and the commercial unit. A power supply 28, a distribution board 23, and an operation display panel 25 are connected.

  For example, the control device 21 supplies the electric power generated by the solar power generation device 14 to the shared facilities such as the lighting 50 and the auto lock 52 via the distribution board 23, or charges the storage battery 17 with surplus power. Control is performed such as supplying electric power stored in the storage battery 17 to each shared facility via the distribution board 23 and selling surplus power to the electric power company via the commercial power supply 28. In addition, when charging the storage battery 17 using the commercial power supply 28, the control device 21 also performs control such as charging in a time zone in which a charge such as midnight power is inexpensive.

  As with each dwelling unit 18, the operation display panel 25 includes a display panel such as a liquid crystal display device, and also includes operation buttons and the like for performing settings related to power. The operation display panel 25 is capable of displaying and setting information related to electric power when operated by a landlord of the apartment house. As the operation display panel 25, a touch panel type is applied in the present embodiment, but is not limited thereto.

  Specifically, in this embodiment, the operation display panel 25 charges the storage battery 17 with surplus power remaining in the shared facilities of the shared unit 27 out of the power generated by the solar power generation device 14. It is possible to set the ratio of electricity sales.

  The control device 21 is connected to a network 30 such as the Internet, and can communicate with a terminal device 32 that can be connected to the network 30. In the present embodiment, the terminal device 32 can remotely control the ratio of power storage and power sale that can be set on the operation display panel 25. That is, by transmitting information indicating the ratio of power storage and power sale from the terminal device 32, the control device 21 controls power storage in the storage battery 17 and power sale to the power company according to the transmitted ratio. It is like that.

  Here, the control regarding the supply of the generated electric power performed in the control apparatus 20 is demonstrated. In the following, the control performed by the control device 20 of each dwelling unit 18 will be described as a representative, but it is assumed that the control device 21 of the shared unit 27 can perform the same control.

  The electric power generated by the solar power generation device 14 is supplied to the control device 20 and is supplied from the control device 20 to each living room 26 via the distribution board 22.

  The control device 20 basically supplies the generated power to the distribution panel 22 so that the power generated by the solar power generation device 14 is used in each dwelling unit, and surplus power that is not used is supplied to the storage battery 16. Control is performed to charge or sell power to the power company via the commercial power supply 28. The generated power of the solar power generation device 14 may be supplied to the distribution board 22 after being directly stored in the storage battery 16 instead of surplus power, or sold directly.

  As described above, the power storage in the storage battery 16 and the power sale to the electric power company are controlled according to a ratio set in advance by the operation display panel 24. For example, when 100% of power storage is set as the ratio of power storage and power sale on the operation display panel 24, the control device 20 performs control so that the storage battery 16 is charged without selling power, and the storage battery 16 is fully charged. When it becomes, it controls to sell electricity. When 100% power sale is set on the operation display panel 24, the control device 20 performs control so as to sell all surplus power in the generated power without storing power in the storage battery 16. In addition, when 50% is set for each of the power storage and power sale ratios on the operation display panel 24, the control device 20 charges the storage battery 16 and sells electricity to the power company by 50% each. Control. At this time, the ratio of the electricity storage and the power sale is calculated based on the surplus power generated in the immediately preceding fixed time, and the electricity storage and the electricity sale are performed. For example, when the surplus power generated in the previous hour is 1 kWh and the ratio of power storage and power sale is set to 50%, 0.5 kWh must be sold for the next hour. And the rest is charged. Alternatively, 0.5 kWh is always stored, and the remaining power is sold to control to follow the set ratio. In the above-described example, the ratio of power storage and power sale has been described by taking power storage: power sales = 100: 0, 0: 100, or 50:50 as an example, but the present invention is not limited to this.

  Next, a description will be given of processing for setting power storage and power selling in the apartment house power supply system 10 according to the embodiment of the present invention configured as described above. FIG. 3 is a flowchart illustrating an example of a processing flow when setting power storage and power sale in each dwelling unit in the apartment building power supply system 10 according to the embodiment of the present invention. 3 is started when an instruction to operate the operation display panel 24 to set power storage and power sale is given.

  When the operation display panel 24 is operated to give an instruction to set power storage and power sale, in step 100, a predetermined power storage / power sale ratio setting screen is displayed on the operation display panel 24 and the process proceeds to step 102. For example, a screen as shown in FIG. 4A is displayed as the power storage / power sale ratio setting screen. “Economic emphasis” in FIG. 4A is selected when all power is sold, “environment emphasis” is selected when all power is stored, and “ratio selection” is when the ratio is arbitrarily changed. Selected.

  In step 102, it is determined whether the operation display panel 24 has been operated to select "Economical emphasis". If the determination is affirmative, the process proceeds to step 104. If the determination is negative, step 106 is performed. Migrate to

  In step 104, the control device 20 is set so as to sell all surplus power, and the series of processing ends. As a result, the control device 20 supplies the surplus power remaining from the power generated by the solar power generation device 14 to the common room 27 of each living room 26 and the apartment house 12 through the distribution board 22 to the power company. Controlled to sell electricity.

  In step 106, it is determined whether or not “environment-oriented” has been selected by operating the operation display panel. If the determination is affirmative, the process proceeds to step 108; The process proceeds to step 110 on the assumption that “select ratio” is selected.

  In step 108, the surplus power is stored in the storage battery 16, and the control device 20 is set to sell power when the storage battery 16 is fully charged, and the series of processing ends. As a result, in the control device 20, the surplus power remaining from the power generated by the solar power generation device 14 through the distribution board 22 and supplied to the shared portions 27 of the living rooms 26 and the apartment house 12 is stored in the storage battery 16. It is controlled so as to be charged, and is controlled so as to sell power to the electric power company when the storage battery 16 is fully charged.

  In step 110, a predetermined setting ratio selection screen is displayed, and the routine proceeds to step 112. As the setting ratio selection screen, for example, a screen as shown in FIG. 4B is displayed. In FIG. 4B, the ratio can be arbitrarily changed by performing an operation of instructing “▲” or “▼”.

  In step 112, it is determined whether or not the ratio selection has been completed. The determination is made, for example, by determining whether or not the operation of instructing “▲” or “▼” in FIG. 4B is performed and the ratio is determined, and the operation of instructing “decision” is performed, The process waits until the determination is affirmed and proceeds to step 114.

  In step 114, the power storage / power sale setting is performed in the control device 20 in accordance with the set ratio, and the series of processing ends. As a result, the control device 20 controls the power storage and the power sale to the storage battery 16 so that the ratio is arbitrarily set. For example, while monitoring the surplus power amount for a predetermined time immediately before, control is performed to alternately store power in the storage battery 16 and sell power to the power company so that the set ratio is obtained.

  As described above, in the residential building power supply system 10 according to the present embodiment, by operating the operation display panel 24, the power generated by the solar power generation device 14 is stored in the storage battery 16 and supplied to the power company. It is possible to set the power sale for each dwelling unit individually, and the ratio of the power storage and the power sale can be set as desired according to the will of the resident. The generated power can be used according to the needs of residents.

  In single-family apartments, the amount of electricity used during the day is low, and the power generated is likely to be surplus, and is likely to be stored or sold. The system 10 is suitable for the housing complex 12 for single persons.

  Although the flowchart of FIG. 3 is shown as an example, it is not limited to the above processing order, and the order of each determination may be appropriately changed. For example, the determination of whether or not emphasis is placed on economics in step 102 and the determination on whether or not emphasis is placed on environment in step 106 may be reversed, and whether the emphasis is on economics, environmental considerations, or ratio setting. May be determined based on the operation content of the operation display panel 24, and the subsequent processing may be performed.

  Further, the power storage / power sales ratio setting screen is not limited to the above example, and may be a screen as shown in FIG. 4C, for example. In the case of FIG. 4 (C), the ratio of the electrical storage to the storage battery 16 and the electric power sale to an electric power company is predetermined, and the example selected from three predetermined ratios is shown. Here, in FIG. 4C, when “power storage / power sales 0% / 100%” is selected, 100% power is sold, and when “power storage / power sales 100% / 0%” is selected. Stores 100%, and when “power storage / 50% power sale / 50%” is selected, control is performed so that power storage and power sale are each 50%.

  Further, the method of displaying the ratio of power sale and storage is not limited to “%” display, and for example, the ratio may be displayed using characters such as “many” and “small”.

  In the above embodiment, an example of selling power to a power company via the commercial power supply 28 has been described in the case of selling power, but the present invention is not limited to this, and a power storage battery is provided to sell power. You may make it electrify. For example, as shown in FIG. 5, you may make it further provide the storage batteries 34 and 35 for a power sale with respect to said embodiment. That is, when selling the power according to the settings, the control devices 20 and 21 control the power sale storage batteries 34 and 35 to store the power so that the power sale storage batteries 34 and 35 are stored by a predetermined power recovery company. You may make it sell electricity by collect | recovering (battery exchange). In addition, in the example of FIG. 5, the storage batteries 34 and 35 for power sale are shown as examples provided in each dwelling unit 18 and the common unit 27 of the apartment house 12. Power storage batteries 34 and 35 may be provided. In addition, as a specific method for selling power by the power sale storage batteries 34 and 35, for example, the control devices 20 and 21 monitor the amount of power charged in the power sale storage batteries 34 and 35, and the amount of stored power is calculated. It can be done by paying the compensation by the power recovery company by transmitting it to the power recovery company via the network 30.

  Moreover, in said embodiment, although the example which provides the storage battery 16 for every dwelling unit was demonstrated, it is not restricted to this, For example, as shown in FIG. 6, one storage battery 38 is provided with respect to several dwelling units. You may make it provide.

  When one storage battery 38 is provided for a plurality of dwelling units as shown in FIG. 6, the storage battery 38 is connected to each dwelling unit via the control system 36 in order to manage the amount of power from each dwelling unit. As a result, when the control system 36 monitors the amount of power supplied from each dwelling unit, when using power from the storage battery 38, it is possible to perform control such as using only the amount stored. For example, when dwelling units A18A to akW, dwelling units B18B to bkW, and dwelling units C18C to ckW are stored in the storage battery 38 via the control system 36, the control system 38 sets the upper limit of power that the dwelling unit A18A can use from the storage battery 38. By limiting the upper limit of power that can be used from the storage battery 38 to bkW and limiting the upper limit of power that can be used from the storage battery 38 to ckW, the power corresponding to the amount stored is used. It becomes possible.

  In the above embodiment, the operation display panel 24 has been described as an example in which a touch panel type is applied. However, a button type, a voice authentication type, a fingerprint authentication type (pulse authentication type), or the like may be applied. . For example, when the button type is applied, a mode button such as a power sale mode button or a power storage mode button may be provided, and the ratio of power storage and power sale may be set by operating the mode button. In addition, when applying the voice authentication formula, when “biden” is recognized through a microphone, 100% power selling setting is set, and when “chikuden” is recognized through a microphone, 100% power storage is performed. If the setting is made or “biden 50% chikuden 50%” is recognized through a microphone, the ratio of the electricity storage and the power sale may be set to 50%. Furthermore, when the fingerprint authentication method is applied, when the right hand fingerprint of a resident of each dwelling unit (for example, a predetermined representative) is recognized, the power selling setting is set to 100%, and the left hand fingerprint is recognized. In addition, when 100% power storage is set and another fingerprint is recognized, the ratio of power storage and power sale may be set to 50%. Alternatively, these may be combined as appropriate to enable the ratio setting of power storage and power sale.
