  Further, the tablet terminal 6 transmits / receives a signal to / from the power generation control unit 16 and the charge / discharge control unit 27 via the remote controller 5 to instruct, operate, and set the operation mode and operation command of the power supply system 1. The operation information of the power supply system 1 is displayed on the display operation unit 6a.

  In the power supply system 1 having the above configuration, when the amount of sunshine during nighttime or daytime is reduced and the solar battery 11 is not generating power, the power supply system 1 supplies the received power from the commercial power system CS to the household load L. To do. At this time, the power generation control unit 16 stops the operation of the solar battery power conditioner 12 so that power is supplied from the commercial power system CS to the household load L. In addition, the charge / discharge control unit 27 operates the storage battery power conditioner 22 to store midnight power in the storage battery 21 from the commercial power system CS or supply the power stored in the storage battery 21 to the household load L. .

  When the solar cell 11 can generate power such as in the daytime when the amount of sunshine is sufficient, the power supply system 1 supplies the power generated by the solar cell 11 to the household load L. At this time, the power generation control unit 16 activates the solar cell power conditioner 12 to place the interconnection relay 15 in a connected state so that power is supplied from the solar power generation device 10 and the commercial power system CS to the household load L.

  When the solar cell 11 generates sufficient power for the demand power of the household load L, the power supply system 1 reversely flows the surplus power generated by the solar cell 11 to the commercial power system CS. At this time, the power generation control unit 16 places the interconnection relay 15 in a connected state so that power is supplied from the solar power generation device 10 to the home load L and the commercial power system CS. Then, the charging / discharging control unit 27 disconnects the interconnection relay 26 so that only the generated power of the solar battery 11 is reversely flowed with respect to the commercial power system CS and the power stored in the storage battery 21 is not supplied to the commercial power system CS. Put it in a state.

  When the storage battery 21 is not fully charged and the amount of charge of the storage battery 21 is increased, the power supply system 1 stores the generated power of the solar battery 11 or the received power from the commercial power system CS in the storage battery 21. At this time, the charge / discharge control unit 27 operates the storage battery power conditioner 22 to control the photovoltaic power generation apparatus 10 or the obtained power to be stored in the storage battery 21.

  In the economical automatic operation mode, late-night power with a relatively low electricity bill is stored in the storage battery 21, and the generated power of the solar battery 11 and the charging power of the storage battery 21 are prioritized over the power purchase from the commercial power system CS during the day. To the household load L. In the charge priority operation mode, charging of the storage battery 21 is immediately started toward full charge, and when the storage battery 21 reaches full charge, the battery standby is performed. In addition, it shifts to an economical automatic operation mode 24 hours after becoming a standby state. In the clean operation mode, the storage battery 21 is charged during the day when the power generation amount of the solar cell 11 is larger than the power consumption amount of the home load L, and the power consumption amount of the home load L is the power generation amount of the solar cell 11. When there are more, the battery 21 is discharged.

  Transmission of these operation commands in the automatic operation mode to the power generation control unit 16 or the charge / discharge control unit 27 can be executed by the remote controller 5 and the tablet terminal 6. The display operation unit 5a of the remote controller 5 and the display operation unit 6a of the tablet terminal 6 display an operation screen in the automatic operation mode as shown in FIGS. 2 and 3, for example, and can be operated by a touch panel.

  In each operation screen, in addition to the operation keys 5b and 6c in the automatic operation mode, operation keys 5c and 6d related to exchange of setting qualifications for the operation command in the automatic operation mode are also displayed and can be operated.

  According to the operation key 5c of the remote controller 5, it is possible to give and acquire the qualification for the tablet terminal 6 to be set by transmitting the operation command in the automatic operation mode. The remote controller 5 can sequentially assign and acquire operation command setting qualifications to the tablet terminal 6.

  According to the operation key 6d of the tablet terminal 6, it is possible to receive and return from the remote controller 5 that is qualified to transmit and set an operation command in the automatic operation mode. The tablet terminal 6 transmits and sets the automatic operation mode using the operation keys 6c and the like and the operation command of the power storage device 20 via the remote controller 5 when the remote controller 5 is given the qualification to transmit and set the operation command. The automatic operation mode using the operation key 6c or the like or the operation command of the power storage device 20 can be transmitted and set when the qualification to transmit and set the operation command is not given from the remote controller 5. Can not.

  Note that only the tablet terminal 6 is provided with an operation key 6e capable of setting individual operation commands for charging and discharging the storage battery 21 of the power storage device 20. If the tablet terminal 6 is used, the charging and discharging of the storage battery 21 that are detailed operation commands can be manually set with priority over the operation commands that can be performed by the display operation unit 5a of the remote controller 5.

  This allows the user to charge or discharge the storage battery 21 at an intentional timing, or to charge or discharge the storage battery 21 in consideration of the power consumption data of the household load L obtained by the power consumption measurement and collection system 30. The set value of the quantity can be determined. Further, it may be set in cooperation with the power generation amount of solar power generation.

  The passing of the operation mode setting qualification between the remote controller 5 and the tablet terminal 6 of the power supply system 1 will be described along the operation flow shown in FIG. FIG. 4 is a flowchart showing delivery of operation mode setting qualification between the remote controller 5 and the tablet terminal 6 of the power supply system 1.

  When the operation of the power supply system 1 is started (start of FIG. 4), the operation mode can be transmitted and set by the remote controller 5 to the power generation control unit 16 or the charge / discharge control unit 27 in the initial stage. The transmission and setting of the operation mode and the like are disabled (step # 101 in FIG. 4).

  Next, the remote controller 5 determines whether or not a setting qualification such as an operation mode for the power generation control unit 16 or the charge / discharge control unit 27 is given to the tablet terminal 6 by the operation of the operation key 5c by the user (step # 102). ). When the setting qualification such as the operation mode is not given to the tablet terminal 6 from the remote controller 5 (No in Step # 102), the operation mode setting of the power supply system 1 can be continuously executed from the remote controller 5. .

  When the setting qualification such as the operation mode is given from the remote controller 5 to the tablet terminal 6 (Yes in Step # 102), the remote controller 5 determines the operation mode to the power generation control unit 16 or the charge / discharge control unit 27 by the user using the remote control 5 itself. The setting change cannot be accepted, and the operation mode and the like can be transmitted and set by the tablet terminal 6 (step # 103).

  Next, the remote controller 5 determines whether or not a setting qualification such as an operation mode for the power generation control unit 16 or the charge / discharge control unit 27 has been acquired from the tablet terminal 6 by the operation of the operation key 5c by the user (step # 104). ). When the remote controller 5 has not acquired the setting qualification such as the operation mode from the tablet terminal 6 (No in Step # 104), the remote controller 5 has the setting qualification such as the operation mode by operating the operation key 6d of the tablet terminal 6 by the user. It is determined whether or not it has been returned to the remote controller 5 (step # 105). When the tablet terminal 6 has not returned the setting qualification such as the operation mode to the remote controller 5 (No in Step # 105), while continuously enabling the transmission and setting of the operation mode of the power supply system 1 from the tablet terminal 6, Return to step # 104.

  On the other hand, when the remote controller 5 obtains the setting qualification such as the operation mode from the tablet terminal 6 in Step # 104 (Yes in Step # 104), or the tablet terminal 6 assigns the setting qualification such as the operation mode to the remote control 5 in Step # 105. If it is returned (Yes in step # 105), the process returns to step # 101, and the remote controller 5 enables transmission and setting of the operation mode by itself, and disables transmission and setting of the operation mode and the like by the tablet terminal 6.

  Note that, as described above, an external terminal that accepts an operation command from an external terminal such as the tablet terminal 6 as one of the automatic operation modes, instead of the remote controller 5 giving or acquiring setting qualifications such as the operation mode to the tablet terminal 6 An operation mode may be provided. When the external terminal operation mode is set, an operation command from the tablet terminal 6 is transmitted to the charge / discharge control unit 27 via the remote controller 5.

  The remote controller 5 can switch the operation mode to a mode other than the external terminal operation mode at any time. When the remote controller 5 is operated to switch to another mode, the operation command from the tablet terminal 6 cannot be performed. In addition, when the operation command cannot be performed on the tablet terminal 6 due to the mode switching of the remote controller 5, the fact may be displayed on the tablet terminal 6.

  As described above, the power supply system 1 includes the storage battery 21, the charge / discharge control unit 27 that controls the operation of charging / discharging the storage battery 21, and the display operation unit 5 a, and issues an operation command to the charge / discharge control unit 27. The remote controller 5 that is the first operation unit to be transmitted and set, and the operation command that is more detailed than the operation command that is possible on the display operation unit 5a of the remote control 5 are transmitted to the charge / discharge control unit 27 via the remote controller 5. A tablet terminal 6 that is a second operation unit that can be set. Since individual operation commands for charging and discharging the storage battery 21 cannot be instructed by the display operation unit 5 a of the remote controller 5, their settings are limited to the tablet terminal 6. That is, detailed control of charging and discharging of the storage battery 21 can be executed only using the tablet terminal 6. Therefore, a detailed operation command for the storage battery 21 cannot be easily set from any operation unit, and can be transmitted and set only by using the tablet terminal 6.

  Further, the remote controller 5 can grant and acquire the qualification for setting the operation command for the automatic operation mode to the tablet terminal 6, and the tablet terminal 6 can store the storage battery 21 when the qualification for setting the operation command is given from the remote control 5. The operation command for the storage battery 21 cannot be set when the operation command setting qualification is not given from the remote controller 5. Thereby, the setting of the individual operation commands for charging and discharging the storage battery 21 can be executed only when the tablet terminal 6 acquires the qualification from the remote controller 5. Therefore, opportunities for setting detailed operation commands for the storage battery 21 can be limited. In addition, since the remote controller 5 can sequentially acquire the operation command setting qualification for the storage battery 21 from the tablet terminal 6, it is also possible to restrict the transmission and setting of the operation command by the tablet terminal 6.

  In addition, the power supply system 1 has a plurality of operation modes, charging / discharging control for the storage battery 21 based on the operation mode is executed by the operation command transmitted from the remote controller 5, and based on the operation mode by the operation command transmitted by the tablet terminal 6. Charge / discharge control that is prioritized over charge / discharge control for the storage battery 21 can be executed. Therefore, opportunities for setting detailed operation commands for the storage battery 21 can be limited.

  The tablet terminal 6 includes a receiving unit 6b that receives information on the power consumption of the household load L, and a display operation unit 6a that displays the information, and is a charge / discharge control that controls the charging / discharging operation of the storage battery 21. The operation command for the storage battery 21 is transmitted to the remote controller 5 that transmits the operation command to the unit 27, which is more detailed than the operation command that can be performed by the display operation unit 5a of the remote controller 5. Thereby, the detailed control of charge and discharge of the storage battery 21 can be executed only using the tablet terminal 6. Therefore, a detailed operation command for the storage battery 21 cannot be easily set from any operation unit, and can be transmitted and set only by using the tablet terminal 6.

  The power supply system 1 also includes a power consumption measurement collection system 30 that measures power consumption of the household load L and collects power consumption data, and the tablet terminal 6 receives power consumption from the power consumption measurement collection system 30. Acquire and display data. As a result, the power supply system 1 measures and collects power consumption data of the household load L using the power consumption measurement collection system 30. And the power consumption data of the household load L can be provided to the user using the tablet terminal 6. Therefore, the user can arbitrarily arbitrarily set the operation commands for charging and discharging the storage battery 21 based on the power consumption data of the household load L obtained from the tablet terminal 6.

  The power consumption measuring and collecting system 30 includes a power consumption measuring device 31 that measures the power consumption of the home load L installed at the insertion port of the power plug Lp of the home load L, and the power consumption measuring device 31 Power consumption data collecting device 32 that receives and collects data, so that power consumption can be easily measured simply by inserting the power plug Lp of the household load L into the outlet. It is possible to collect.

  Further, since the power supply system 1 includes the solar power generation device 10, the power generated by the solar battery 11 can be supplied to the household load L or stored in the storage battery 21. Therefore, in the power supply system 1 including the solar power generation device 10, the power storage device 20 can be operated in the automatic operation mode from both the remote controller 5 and the tablet terminal 6, and individual operation commands for charging and discharging the storage battery 21 can be set. It is possible to limit the setting to the tablet terminal 6.

  Furthermore, in the control method of the power supply system 1, a step of transmitting and setting an operation command to the charge / discharge control unit 27 that controls the charge / discharge operation of the storage battery 21 using the display operation unit 5a of the remote controller 5, and Using the tablet terminal 6 to transmit and set an operation command that is more detailed than an operation command that can be performed by the display operation unit 5a of the remote control 5 to the charge / discharge control unit 27 via the remote control 5. As a result, detailed operation commands for the storage battery 21 cannot be easily set from any of the operation units, and can be transmitted and set only by using the tablet terminal 6.

  Thus, according to the configuration of the above-described embodiment of the present invention, in addition to automatically controlling charging and discharging of the storage battery 21, charging and discharging of the storage battery 21 are individually performed in response to a user request. A power supply system 1 that can be controlled in detail, a tablet terminal 6 that is a terminal device, and a method for controlling the power supply system 1 can be provided.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

  For example, in the above embodiment, the remote controller 5 manages the qualification to control the storage battery power conditioner 22, but this purpose is that different operation commands are transmitted simultaneously by the remote controller 5 and the tablet terminal 6. This is to prevent it. Therefore, the remote controller 5 is not limited to priority, and the tablet terminal 6 may manage the qualification for performing control with priority over the remote controller 5.

  Furthermore, the qualification to be controlled may be transferred by a plurality of operation terminals, and transmission of an operation command from the operation terminal holding the qualification may be prioritized. When there are three or more operation terminals, priority may be given to the qualification priority for control.

  In the embodiment of the present invention, the control pattern of each automatic operation mode may be held by any one of the power generation control unit 16, the charge / discharge control unit 27, the remote controller 5, and the tablet terminal 6. For example, when the charge / discharge control unit 27 holds the control pattern of each operation mode, an operation command for selecting the operation mode may be transmitted from the remote controller 5 to the charge / discharge control unit 27. Thereby, the charging / discharging control part 27 performs control of charging / discharging of the storage battery 21 based on an operation mode, and the electric power supply system 1 operate | moves in the selected operation mode. Further, for example, when the remote controller 5 holds the control pattern of each operation mode, an operation command related to charge / discharge based on the control pattern of the operation mode may be transmitted from the remote controller 5 to the power generation control unit 16 or the charge / discharge control unit 27. Thereby, the power generation control unit 16 and the charge / discharge control unit 27 execute a command related to charging / discharging of the storage battery 21 controlled by the remote controller 5 based on the operation mode, and the power supply system 1 operates in the selected operation mode. .
