Each storage battery stores electric power generated by PV (Photovoltaics) facilities (not shown) of the first user Ua and the second user Ub or electric power input from the electric power system 40, respectively.

The electric power stored in each storage battery is consumed by the load 28 and the load 38, respectively, or is reversely flowed (power sold) to the power system 40.

Each storage battery has a rated capacity (kWh) that can be charged by the system. In the present embodiment, the storage capacity of the first user Ua is 6 kWh, and the storage capacity of the second user Ub is 20 kWh. Although this embodiment demonstrates the case where the rated capacity of the storage battery of the 1st user Ua is smaller than the rated capacity of the storage battery of the 2nd user Ub, the rated capacity of the storage battery of the 1st user Ua is rated of the storage battery of the 2nd user Ub. The present invention is similarly applicable when the capacity is larger than the capacity or the rated capacity of each storage battery is equal.

In the present embodiment, the EMS controls the operation of the battery system in each user's power system. And HEMS acquires and monitors various electric energy values from a battery system, another apparatus (a load, a smart meter), etc. The server 10 receives information on various electric energy from the HEMS and instructs the EMS to control the operation of the battery system.

The apparatus configuration of the information processing system 1 of the present invention including the above example is exemplified below, but is not limited thereto.
(A1) Configuration in which each user uses three devices including EMS, a battery system, and HEMS (configuration example of this embodiment)
EMS and HEMS are each connected to the network 3. The EMS receives instructions from the server 10 to control the operation of the battery system, and the HEMS acquires various information and transmits it to the server 10.
(A2) Configuration in which each user uses a device in which an EMS and a battery system are integrated and two devices including the HEMS. The HEMS and the integrated device are connected, and the HEMS is connected to the network 3. The HEMS receives instructions from the server 10 to control the operation of the battery system, and acquires various information and transmits it to the server 10.
(A3) Configuration in which each user uses two devices including a device in which EMS and HEMS are integrated and a battery system The battery system is connected to the integrated device, and the integrated device is connected to the network 3. The integrated device receives instructions from the server 10 and controls the operation of the battery system, and acquires various types of information and transmits them to the server 10. For example, the function of the EMS-HEMS integrated device of the present invention may be added by updating the firmware of the HEMS.
(A4) Configuration in which server 10 has EMS function Each user's HEMS and battery system are connected to network 3. The server and each user's HEMS and battery system may be connected via a gateway.
The server 10 having the EMS function may directly control the operation of the battery system, or may control the operation of the battery system via the HEMS. Further, the HEMS acquires various information and transmits it to the server 10.
(A5) Configuration using EMS that can be shared and used for a plurality of battery systems The shared EMS is connected to the battery system of a plurality of users and connected to the network 3. The shared EMS receives instructions from the server 10 and controls the operations of the battery systems of a plurality of users, acquires various information from the HEMS of each user, and transmits it to the server 10. The shared EMS may be installed in a predetermined place such as a utility pole, for example.

In this embodiment, in order to implement | achieve the movement of the electric power between each storage battery based on the electric power sales contract established between the 1st user Ua and the 2nd user Ub, charging / discharging from each server EMS to each user's EMS. Control is instructed. For example, when power is sold from the first user Ua to the second user Ub, discharging is instructed to the EMS of the storage battery of the first user Ua, and charging is instructed to the EMS of the storage battery of the second user Ub.

Here, the power discharged from the storage battery of the first user Ua is reversely flowed to the power system 40, and the storage battery of the second user Ub is supplied with power from the power system 40 and charged. In other words, the electric power discharged from the storage battery of the first user Ua is not directly charged into the storage battery of the second user Ub, but the electric power of the contract power amount according to the contract contents from each storage battery is respectively supplied to the electric power system 40. On the other hand, it is discharged (reverse power flow) and charged (supplied) from the power system 40.

Moreover, as above-mentioned, the capability of the storage battery of the 1st user Ua and the 2nd user Ub is also various, and the electric energy which can be discharged in a fixed time differs from the electric energy which can be charged.
Therefore, the discharge timing of the first user Ua and the charging timing of the second user Ub do not necessarily have to be the same, and may be managed and controlled individually. However, a configuration that controls the charge / discharge amount according to the capacity of each storage battery and synchronizes the timing of charge / discharge is not excluded.

For example, although the timing of charging / discharging is illustrated below, it is not limited to these. The following may be combined.
(B1) Charging and discharging are controlled in synchronization.
(B2) The charge amount and the discharge amount are controlled so as to be the same amount in a 30-minute cycle.
(B3) With respect to the corresponding charge amount and discharge amount, charging and discharging are controlled at different timings regardless of the period such as 30 minutes.

Moreover, the storage battery of each user is at least a part (for example, predetermined) used by the user among large storage batteries shared and used by a plurality of users in addition to those installed in the user's home or store. Or other cell sections). In this case, information necessary for controlling the cell section used by the user (for example, to access the EMS IP (Internet Protocol) address of the storage battery, the identification information of the user's cell section, and the cell section) Authentication code information (password or the like) necessary for performing the authentication process is previously registered in the server 10 as a user. Alternatively, the use of the present system may be provided as a service to a user of a large storage battery, and in that case, the server 10 may legally obtain information on cell sections and users from a storage battery management company.

The server 10 is connected to the first user terminal 50 and the second user terminal 60 via the network 3, and a screen for making a power sales contract between the first user Ua and the second user Ub, and a storage battery of each user A screen showing information such as the status of the user is displayed on each user terminal.

A method for displaying various screens on the first user terminal 50 and the second user terminal 60 is not particularly limited. For example, a website for each user is created on a web server (not shown), and a browser or a predetermined screen is displayed on the user terminal. The application may be activated to access and display the website, or a predetermined application may be activated on the user terminal to obtain necessary information from the server 10 and display it.

<Information processing apparatus 100>
Next, the information processing apparatus 100 will be described with reference to FIG.

The information processing apparatus 100 has a first storage battery (battery system 22) and a first user Ua who is a seller of power, and a second user who has a second storage battery (battery system 32) and is a buyer of power. The acquisition unit 102 that acquires contract information including the amount of contract electric power traded with the user Ub, and power from the first storage battery (storage battery of the first user Ua) to the second storage battery (storage battery of the second user Ub) Using the charge / discharge amount information, the receiving unit 104 that receives charge / discharge amount information related to at least one of the discharge amount of the storage battery of the first user Ua and the charge amount of the storage battery of the second user Ub, The determination unit 106 that determines whether or not the movement of the contract power amount has been completed, and the contract information acquired by the acquisition unit 102 are displayed on at least one of the first user terminal 50 and the second user terminal 60, One, when the movement of the contracted power amount of the power is determined to be completed, a display unit 108 for displaying the information indicating that at least one of the first user terminal 50 and the second user terminal 60.

In this specification, “acquisition” means that the device itself obtains data or information stored in another device or storage medium (active acquisition), for example, requests or inquires of another device. Receiving data, accessing and reading out other devices and storage media, etc., and inputting data or information output from other devices into the device (passive acquisition), for example, distribution (or , Transmission, push notification, etc.) and / or receiving received data or information. It also includes selecting and acquiring from received data or information, or selecting and receiving distributed data or information.

The screen displayed by the display unit 108 is exemplified in the transaction confirmation screen 270 of FIG.

The transaction confirmation screen 270 includes a discharge-side storage battery state display unit 262, a charge-side storage battery state display unit 264, a movement completion icon display unit 272, and a movement completion message display unit 274 that displays a message indicating that the power transaction has been completed. Including.

In FIG. 19, only the charging-side storage battery state display unit 264 is hatched (for example, displayed in green) so as to indicate that all power has moved from the discharging-side storage battery state display unit 262 to the charging-side storage battery state display unit 264. have. On the icon of the movement completion icon display unit 272, for example, information such as the completion of the movement of power and the amount of power moved may be drawn. The icon may be given a predetermined animation effect such as blinking or highlighting. The movement completion message display unit 274 displays a message indicating that the movement of power has been completed.

In the present embodiment, when the first user Ua purchases a product with power, the first user terminal 50 is used to make a power purchase / purchase contract. In addition, as described above, the storage battery of the second user Ub has a larger power capacity and higher output capacity than the storage battery of the first user Ua, so that the second user Ub storage battery is charged with the contract power amount. The time required to discharge the contract power amount from the storage battery of the first user Ua is longer than the required time. Therefore, the determination unit 106 determines whether or not the transfer of the contract power amount has been completed using the storage battery information indicating the discharge amount of the storage battery of the first user Ua. Therefore, the receiving part 104 should just receive the storage battery information which shows the discharge amount of the storage battery of the 1st user Ua at the time of moving electric power at least from the storage battery of the 1st user Ua to the storage battery of the 2nd user Ub.

Furthermore, the electric power discharged from the storage battery of the first user Ua does not necessarily have to be charged in the storage battery in the second user Ub. Electric power corresponding to the contract power amount may be supplied from the electric power system 40 to the second user Ub and consumed by the load 38, for example.
Further, the second user Ub may not have a storage battery, and the present invention includes a configuration in which the power purchased from the first user Ua is merely consumed by the load 38 of the second user Ub.

The storage battery information storage unit 112 (FIG. 5) can have two data structure examples. The first example is the storage battery information storage unit 112a in FIG. 5A, and storage battery information such as the rated capacity, rated output, and model of the storage battery is stored in association with the identification information (user ID) of each user for each user. Is done. The second example is the storage battery information storage unit 112b of FIG. 5B, in which storage battery information such as the rated capacity, rated output, and model of the storage battery is stored in association with the storage battery identification information (storage battery ID). In the latter example, the storage battery information corresponding to the storage battery ID for each user in the user information storage unit 150 of FIG. 10 can be read from the storage battery information storage unit 112b and used.

The storage battery information stored in the storage battery information storage unit 112a and the storage battery information storage unit 112b may be input from the registration screen using a user terminal and transmitted to the server 10 at the time of user registration or at any time by the user's HEMS. It may be acquired from the storage battery and transmitted to the server 10. The storage battery information storage unit 112b may be created based on information of each manufacturer and held in the storage device 110.

6, storage battery state information storage unit 114 stores storage battery state information received from each user's power system (for example, HEMS, EMS, etc.) in association with the user ID. The receiving part 104 should just receive the status information of the storage battery of at least one of the 1st user Ua and the 2nd user Ub. The reception timing is regular or as needed.

The status information includes, for example, the date and time when the status information was received from the power system, the current storage battery capacity, free capacity, operation information (operation stop, charge, discharge, standby, full charge, error), error information (communication error, Information such as a system error). The storage battery state information storage unit 114 only needs to store at least information on the current storage capacity of the storage battery, and may not store other information. Furthermore, the state information may include a dischargeable capacity (or chargeable capacity) calculated by the control unit 130 based on information on the current storage capacity and the rated capacity of the storage battery.

These pieces of information are displayed on a screen where the first user Ua confirms the remaining capacity of the storage battery when the first user Ua and the second user Ub make a power sales contract.

In the contract information storage unit 120 in FIG. 7A, the contract information acquired by the acquisition unit 102 is stored. The contract information includes at least the user IDs of the first user Ua and the second user Ub and the contract power amount traded between the two parties in association with each other. Further, the contract information may include date and time when the contract is established and identification information (contract number or the like) for identifying each contract.

The timing at which the acquisition unit 102 acquires the contract information is when the contract between the two parties is confirmed in at least one user terminal of the first user Ua and the second user Ub. As will be described later, when at least one of the first user Ua and the second user Ub agrees to the content on the screen for confirming the contract content displayed on at least one of the first user terminal 50 and the second user terminal 60 The control unit 130 may determine that the contract has been established.

FIG. 7B shows an example of the data structure of the contract information storage unit 212 stored in the storage device 210 of the user terminal of each user. The contract information storage unit 212 stores at least the user ID of the contract partner and the amount of power sold in association with each other. In the figure, an example of the contract information storage unit 212 stored in the storage device 210 of the first user terminal 50 of the first user Ua is shown. Further, the contract information storage unit 212 may include date and time when the contract is established and identification information (contract number) for identifying each contract.

In the charge / discharge information storage unit 122 in FIG. 8, information on charge / discharge of each storage battery of the first user Ua and the second user Ub (for example, discharge (charge) start time, discharge (charge) scheduled completion time). ) Is stored in association with the user ID.

The discharge (charging) start time and the scheduled discharge (charging) completion time) are obtained by the control unit 130 based on the state information of each user's storage battery received by the receiving unit 104. The discharge (charge) start time may be a time when the storage battery actually starts a discharge (charge) operation, or an instruction to start discharge (charge) is sent from the information processing apparatus 100 to the EMS of each storage battery. It may be the time or both.

The determination of the charge / discharge completion by the determination unit 106 is based on charge / discharge information (charge amount or discharge amount) of at least one storage battery (for example, the charge / discharge completion time is later) of the first user Ua and the second user Ub. Can be done based on. Therefore, the charge / discharge information storage unit 122 only needs to include charge / discharge information of at least one of the first user Ua and the second user Ub (for example, the charge / discharge completion time is later).

The scheduled discharge (charge) completion time is calculated by the control unit 130 based on the contract discharge (charge) power amount, the storage battery state information (rated output, rated capacity), information on the power consumption by the user load, and the like. The For example, information acquired from the HEMS can be used as the information such as the user's load power consumption, and such information may also be stored for each user in the power consumption information storage unit (not shown) of the storage device 110. .

In the charge / discharge amount storage unit 124 of FIG. 9A, a measured value of the amount of electric power discharged (charged) from the storage battery received by the receiving unit 104 is recorded together with date / time information.

The receiving unit 104 receives the discharge amount and the charge amount from at least one of a measurement device that measures the discharge amount (reverse flow value) of the storage battery of the first user Ua and a measurement device that measures the charge amount of the storage battery of the second user Ub, respectively. Charge / discharge information indicating at least one is received. The measuring device is, for example, a smart meter, HEMS, EMS, power conditioner (PCS: Power Conditioning System), CT (Current Transformer), or the like.

As the measured value of the discharge amount, the discharge amount (kWh) of the storage battery may be acquired from the EMS 24 or HEMS 26 of the first user Ua, or the reverse power flow value (for example, 30) acquired from the smart meter SMa of the first user Ua. Minute value) may be acquired via the HEMS 26.

As the measured value of the charge amount, the storage battery charge amount (kWh) may be acquired from the EMS 34 or HEMS 36 of the second user Ub, or the power consumption amount (for example, 30) acquired from the smart meter SMb of the second user Ub. Minute value or instantaneous value) may be obtained via the HEMS 36. The amount of charge can be calculated from the amount of power consumed acquired from the smart meter SMb and the amount of power consumed by each load 38 of the second user Ub. Furthermore, when the second user Ub has a PV, the power generation amount of the PV may be further used for calculating the charge amount. In other words, the amount of power supplied from the power system 40 (the storage battery of the first user Ua) may be calculated by subtracting the amount of PV power generation from the amount of charge of the storage battery.

The measured value is periodically or whenever the HEMS or each of the measured values is received by the receiving unit 104 until the determination unit 106 determines that the power transfer between the first user Ua and the second user Ub is completed after the contract is established. It is acquired by making an inquiry to the EMS, and stored in the charge / discharge amount storage unit 124 together with date / time information.

In the charge / discharge amount information storage unit 126 in FIG. 9B, for each user, at least one of the information on the amount of electric power that has been discharged (charged) and the amount of remaining electric power that has been discharged (charged) with respect to the planned electric energy to be discharged (charged) Stored with information. Further, the charge / discharge amount information may be indicated by the amount of electric power, or may be indicated by the ratio of the discharge (charge) power amount or the discharge (charge) remaining power amount to the planned discharge (charge) power amount.

Based on the charge / discharge information (charge / discharge amount of the storage battery) received by the reception unit 104, the control unit 130 occupies the contracted power amount from the amount of power that has been moved from the storage battery of the first user Ua to the storage battery of the second user Ub. Calculate the percentage. That is, the control unit 130 may further have a function of calculation means (not shown).
The charge / discharge amount information storage unit 126 stores a value calculated by the control unit 130 based on the contract power amount and the charge amount or discharge amount stored in the charge / discharge amount storage unit 124.

As will be described later, the display unit 108 reads the information in the charge / discharge amount information storage unit 126, and the amount of power that has been moved to at least one of the first user terminal 50 and the second user terminal 60 becomes the contracted power amount. By displaying an information screen indicating the ratio (%), the user can be informed of the current power transfer status.

The information processing method of the information processing apparatus 100 of the present embodiment configured as described above will be described below.

The display unit 108 causes the dischargeable capacity display unit 232 to display the dischargeable capacity of the first user Ua read from the storage battery state information storage unit 114 of FIG. In the example of FIG. 13, the 1st user Ua has shown the power transaction screen 230 in the case of purchasing the goods of the store 70 of the 2nd user Ub with electric power. The product selection screen 240 of FIG. 14 may be displayed on the first user terminal 50 of the first user Ua. The product selection screen 240 displays a purchased product, its unit price, and a corresponding amount of power using a pull-down menu or a drum roll type user interface, so that the purchased product can be selected.

The display unit 108 causes the transaction information display unit 234 to display information such as the unit price and the converted power amount for each product read from the power conversion information storage unit 128 of FIG.

Here, the case where the first user Ua visits the store 70 will be described as an example. For example, in online shopping, the corresponding power amount may be displayed on the product purchase page together with the product price. Then, it may be possible to select whether to pay by currency or to pay by electric power when inputting the payment conditions for the purchased product.

Also, it may be possible to display information on a plurality of business partners (power compensation information, etc.) in a list, etc., and the first user Ua can select a business partner from the list.

Returning to FIG. 12, when the first user Ua decides that the transaction of power is performed according to the transaction content on the power transaction screen 230 and the determination button 236 is operated (step S <b> 211), the transaction content is notified to the server 10. (Step S213). The acquisition unit 102 acquires the transaction content as contract information and stores it in the contract information storage unit 120 of FIG.

Then, the display unit 108 reads the contract information from the contract information storage unit 120 in FIG. 7A, and displays the contract content confirmation screen 250 in FIG. 16A on the first user terminal 50 (step S215). If the agreement is agreed, the first user Ua presses the OK button 252. When canceling or correcting the contract, the first user Ua presses the cancel button 254. When the 1st user terminal 50 receives pressing of the cancel button 254, it can return to the electric power transaction screen 230 (FIG. 13), and can correct transaction content.

When the first user terminal 50 accepts pressing of the OK button 252, the server 10 is notified of the confirmation of the contract contents (step S 217), and the display unit 108 displays the transaction confirmation screen 260 of FIG. (Step S219). At this time, the server 10 updates the contract information storage unit 120 (FIG. 7A) with the confirmed contract information. The first user terminal 50 and the second user terminal 60 may also store the contract information in the contract information storage unit 212 (FIG. 7B), respectively.

In this example, the first user Ua confirms and approves the contract contents (by pressing the OK button 252), and the contract is finalized. However, the contract finalizing method may be another method. Although illustrated below, it is not limited to these.

In the display pattern (d2) described above, the display unit 108 indicates to at least one of the first user terminal 50 and the second user terminal 60 the ratio of the actual discharge amount of the storage battery of the first user Ua to the contract power amount. Display (update) information repeatedly.
This display pattern is a suitable method when the discharging speed of the storage battery of the first user Ua is slower than the charging speed of the storage battery of the second user Ub.

In the display pattern (d3) described above, the display unit 108 indicates, to at least one of the first user terminal 50 and the second user terminal 60, the ratio of the actual charge amount of the storage battery of the second user Ub to the contract power amount. Display (update) information repeatedly.
This display pattern is a suitable method when the charging speed of the storage battery of the second user Ub is slower than the discharging speed of the storage battery of the first user Ua.

Each value used to calculate the discharge amount or the charge amount ratio can be read from the charge / discharge amount information storage unit 126 and used for the arithmetic processing. In addition, you may further memorize | store the information of the calculated discharge amount or the ratio of charge amount in the charge / discharge amount information storage part 126 in association with date information for every user.

Also, as will be described later, the actual discharge amount of the first user Ua and the actual charge amount of the second user Ub may not be the same due to the capacity difference of each storage battery. In the pattern (d1), for example, the actual discharge amount of the first user Ua is regarded as the charge amount of the second user Ub (or the actual charge amount of the second user Ub is the discharge amount of the first user Ua. It also includes cases where arithmetic processing is performed.

The hatched part of the transaction confirmation screen 260 is displayed with a different color from the other part, for example. Here, for example, it is assumed that the hatched portion is shown in green. As charging / discharging progresses between the storage batteries of the first user Ua and the second user Ub, the area of the hatching portion of the discharge-side storage battery state display unit 262 decreases, and the area of the hatching portion of the charge-side storage battery state display unit 264 increases. It will become. Moreover, the display part 108 may perform and draw on the discharge side storage battery state display part 262 and the charge side storage battery state display part 264, respectively, with an animation effect indicating that charging / discharging is progressing. For example, during discharging, an animation effect is applied such that the hatching portion of the discharge-side storage battery state display unit 262 moves downward, and during charging, the hatching portion of the charge-side storage battery state display unit 264 faces upward. It may be drawn with an animation effect such as moving.

The effect is drawn. In addition, when charging / discharging is interrupted, an icon indicating that is blinked in red (for example, the charging / discharging state display unit 266 in FIG. 17B) and displayed in green when charging / discharging is completed. For example, the color or shape may be changed or the display method (animation or the like) may be changed according to the state of charge / discharge.

The receiving part 104 receives the information which shows the charging / discharging condition of the storage battery of the 1st user Ua.
When the storage battery of the first user Ua is stopped, the display unit 108 indicates that the discharge from the storage battery of the first user Ua is stopped on either the first user terminal 50 or the second user terminal 60. Display the information indicating.

When the contract is confirmed on the contract content confirmation screen 250 (FIG. 16A), the control unit 130 charges and discharges the EMS 24 and the EMS 34 that control the storage battery of the first user Ua and the second user Ub storage battery according to the contract information. Is started (steps S221 and S223 in FIG. 12).

The first power system 20 starts discharging from the storage battery to the power system 40 in accordance with the discharge instruction (step S225). In the second power system 30, charging of the storage battery from the power system 40 is started according to the charging instruction (step S227). At this time, the server 10 stores the discharge (charge) start time in the charge / discharge information storage unit 122 (FIG. 8).

Proceeding to FIG. 18, while the storage battery of the first power system 20 is controlled to be discharged (step S233) and the storage battery of the second power system 30 is controlled to be charged (step S235), the display unit 108 is displayed as shown in FIG. The transaction confirmation screen 260 is displayed on the first user terminal 50 while being updated in real time as follows (step S245).

HEMS26 acquires the measured value of the amount of discharges of the 1st electric power system 20 (Step S237), and transmits to server 10 (Step S239). The HEMS 36 acquires the measured value of the charge amount of the second power system 30 (step S241) and transmits it to the server 10 (step S243). In the server 10, the receiving unit 104 receives each measurement value and stores it in the charge / discharge amount storage unit 124 of FIG. Further, the control unit 130 calculates the discharged (charged) power amount and the discharged (charged) remaining power amount, and stores them in the charge / discharge amount information storage unit 126 of FIG.

Then, the display unit 108 reads the discharged (charged) power amount and the discharged (charged) remaining power amount from the charge / discharge amount information storage unit 126 of FIG. 9B, and updates the transaction confirmation screen 260 (step). S245).

Then, based on the discharged (charged) power amount read from the charge / discharge amount information storage unit 126, the determination unit 106 determines whether or not the power transfer between the first user Ua and the second user Ub is completed. Here, the processing of acquisition, transmission, screen update, and movement completion determination (steps S233 to S247) of the charge / discharge amount is repeatedly executed in real time periodically or at any time until completion of power transfer is detected. The

When the completion of the power transfer is detected (step S247), the display unit 108 displays the transaction confirmation screen 270 (FIG. 19) for notifying that the power transfer is completed on the first user terminal 50 (step S249).

As the display method of the discharge-side storage battery state display unit 262 and the charge-side storage battery state display unit 264 that are being charged / discharged in step S245, the following plural patterns can be considered.

The discharge-side storage battery state display unit 262 and the charge-side storage battery state display unit 264 may be displayed separately on the first user terminal 50 and the second user terminal 60, respectively. For example, only the discharge-side storage battery state display unit 262 of FIG. 20B is displayed on the first user terminal 50, and only the charge-side storage battery state display unit 264 of FIG. 20B is displayed on the second user terminal 60. May be displayed.

FIG. 21 and FIG. 22 show other examples of the power transaction screen. In this example, not only the product purchase but also a power sales contract is concluded, and the next store visit point is acquired as the price. In the following, description will be given according to the flow of FIG. 12 and FIG.

The power transaction screen 280a of FIG. 21A is displayed on the first user terminal 50 in step S209 of FIG. 12, and is similar to the transaction confirmation screen 260 of FIG. A storage battery state display unit 264 is included. As illustrated, the discharge-side storage battery state display unit 262 and the charge-side storage battery state display unit 264 may each indicate a contractable power amount.

Furthermore, the power transaction screen 280a includes a confirmation button 281, a cancel button 282, and a price display field 283 for displaying information regarding the buyer's price. In this example, the consideration display field 283 shows incentives (points) per unit of purchased power. In this

store

70, 100 Pt of points that can be used at the next store visit are given to the first user Ua per 1 (kWh). The possession points for each user are stored in a user point information storage unit (not shown) of the storage device 110. When points are given to the user, the points are added to the user's accumulated points, and the calculated accumulated points are also stored in the user point information storage unit.

When the first user Ua who confirms the transaction content agrees with the transaction content, the user presses the confirmation button 281. On the other hand, when it is desired to change the transaction content, the cancel button 282 is pressed.
When the cancel button 282 is pressed, a transition is made to a selection screen (not shown) such as a business partner and the amount of power sold, and after selection again, the screen returns to the power trading screen 280a.

When the confirmation button 281 is pressed, the transaction content is notified to the server 10 (step S213), and the power transaction screen 280b of FIG. 21B is displayed on the display unit 108 (step S215). The power transaction screen 280b includes a transaction availability display unit 284, an OK button 285, a cancel button 286, and a message display unit 287.

The transaction possible display part 284 may display an arrow indicating that power can be transferred from the storage battery of the first user Ua to the storage battery of the second user Ub by an image such as an icon. The message display unit 287 displays a message indicating that both the charge and discharge capacities of the storage batteries of the first user Ua and the second user Ub are secured for the contract power amount and can be moved.

Then, when the first user Ua confirming the content confirms the contract, the OK button 285 is pressed. On the other hand, when it is desired to change or cancel the contract contents, a cancel button 286 is pressed.
When the cancel button 286 is pressed, a transition is made to a selection screen (not shown) such as a supplier and the amount of power sold, and after selection again, the screen returns to the power transaction screen 280a. When the OK button 285 is pressed, a contract is established. At this time, a contract confirmation notification is transmitted to the server 10 (step S217), and the acquisition unit 102 acquires the contract information. Then, the transaction confirmation screen 260 of FIG. 22A is displayed by the display unit 108 (step S219).

This transaction confirmation screen 260 is the same as FIG. And the control part 130 starts charging / discharging control of each user's storage battery (step S221, step S223, step S225, step S227). On the transaction confirmation screen 260, the charge / discharge amount of the storage battery is displayed while being updated in real time as described above during the charge / discharge control (step S231 in FIG. 18).

And when it is judged that charging / discharging of the storage battery of the 1st user Ua and the 2nd user Ub was completed (step S247 of FIG. 18), the transaction confirmation screen 290 of FIG. 22 is displayed by the display part 108 (step S249). ). The transaction confirmation screen 290 includes a movement completion icon display unit 272 that is the same as the transaction confirmation screen 270 of FIG. 19 and a movement completion message display unit 274 that displays a message indicating that the power transaction has been completed. Furthermore, the transaction confirmation screen 290 includes an acquired point display unit 288 and a current cumulative point display unit 289.

When the determination unit 106 determines that the transfer of the contracted amount of power has been completed, the control unit 130 includes information (points, tickets, charges, etc.) indicating incentives given to the first user Ua as a price for power trading. ) Is output. That is, the control unit 130 further has a function of output means (not shown). Information indicating the incentive is read from the above-described user point information storage unit.

Here, an example in which the information output by the control unit 130 is displayed on the transaction confirmation screen 290 is shown. In addition to the display on the transaction confirmation screen 290, the control unit 130 can perform various output methods such as pop-up display, notification in the notification column, banner display, batch display, message transmission to a predetermined destination, sound output, and vibration output. The information may be output by at least one or a combination of the above.

The acquired point display unit 288 displays the value of the point acquired this time read from the user point information storage unit. Further, the current accumulated point display unit 289 reads the accumulated point value from the user point information storage unit and displays it.

As described above, according to the information processing apparatus 100 of the present embodiment, in the case of buying and selling power, it is possible to easily inform the user of the movement status of power accompanying buying and selling. For example, in the information processing apparatus 100 of the present embodiment, when the determination unit 106 detects the completion of the power transfer, the display unit 108 displays at least the discharge-side storage battery state display unit 262 on the transaction confirmation screen 270 in FIG. It is displayed on the user terminal 50. When it takes time to charge and discharge the storage battery, after the contract is confirmed, it is not possible to immediately check whether or not the charge and discharge are actually completed normally in each storage battery, that is, whether or not the contract contents have been executed.
According to the information processing apparatus 100 of this embodiment, while confirming the halfway result of charging / discharging of each storage battery, a user can be notified of completion of charging / discharging.

Note that the smart meter SMb of the second user Ub measures the power supplied from the power system 40 to the second power system 30 as the amount of power consumption and transmits it to the server of the power company. And the electric power company is calculating the electricity bill of the 2nd user Ub based on this measured value.
However, in the present embodiment, the power supplied from the power system 40 to the second power system 30 includes not only the power supplied from the power company but also the power purchased from the first user Ua. The measured value of the meter SMb includes not only the power purchased by the second user Ub from the power company but also the power purchased from the first user Ua.

Therefore, the server 10 transmits information on the contract power amount purchased by the second user Ub from the first user Ua to the server of the power company. Then, the server of the power company subtracts the contracted power amount from the total power consumption of the second user Ub collected from the smart meter SMb for a predetermined period, and calculates the electricity bill based on the result. If it does in this way, the part of the electric power which the 2nd user Ub purchased from the 1st user Ua will not be included in the billing amount of the electricity bill from the electric power company.

In addition, the smart meter SMa of the first user Ua measures the power reversely flowed from the first power system 20 to the power system 40 and transmits it to the server of the power company. The electric power company purchases the electric power that has flowed backward from the first user Ua and pays the electric power fee to the first user Ua. Therefore, the electric power company calculates a power charge to be paid to the first user Ua based on the measurement value of the smart meter SMa.
However, in the present embodiment, the power reversely flowing from the first power system 20 to the power system 40 includes not only the power sold to the power company but also the power sold to the second user Ub. Therefore, the measured value of the smart meter SMa includes not only the power sold by the first user Ua to the power company but also the power sold to the second user Ub.

Therefore, the server 10 transmits information on the contract power amount that the first user Ua sold to the second user Ub to the server of the power company. Then, the server of the electric power company subtracts the amount of contract power from the reverse flow value of the first user Ua collected from the smart meter SMa, and calculates the electricity bill based on the result. If it does in this way, the part of the electric power which the 1st user Ua sold to the 2nd user Ub will not be included in the electric power charge paid to the 1st user Ua from an electric power company.

(Second Embodiment)
The information processing apparatus 100 according to the present embodiment is different from the above-described embodiment in that the information processing apparatus 100 has a configuration that determines whether power can be transferred between the first user Ua and the second user Ub.
The information processing apparatus 100 according to the present embodiment has the same configuration as that of the above embodiment, and will be described with reference to the drawings of the above embodiment.

First, a configuration for determining whether or not electric power can be transferred will be described.
The control unit 130 determines whether or not the contract amount of power can be transferred from the storage battery of the first user Ua to the second user Ub storage battery. That is, the control unit 130 has a function of availability determination means. When the control unit 130 determines that power can be transferred, the display unit 108 displays a contract screen (for example, confirming contract establishment based on the contract information on at least one of the first user terminal 50 and the second user terminal 60). The contract content confirmation screen 250 in FIG. 16A or the power transaction screen 280b in FIG. 21B is displayed.
For example, when it is determined that the power can be transferred, the display unit 108 transitions the screen 280a illustrated in FIG. 21A described in the above embodiment to the screen 280b illustrated in FIG. 21B.

The conditions for determination of availability are exemplified below, but are not limited thereto. A plurality of the following may be combined. Priorities may be given to the conditions, or conditional expressions including a logical sum or logical product of a plurality of conditions may be used for the determination of availability.
(F1) Desired buy / sell capacity ≦ dischargeable capacity (<charged amount) of the storage battery of the first user Ua is determined to be movable (f2) Desired buy / sell capacity ≦ chargeable capacity of the storage battery of the second user Ub (<empty capacity) If it is determined that it is possible to move (f3) If it is within the range of the desired power sale capacity, it is determined that it is movable (f4) If the desired capacity is within the range of the desired power purchase capacity, it is determined that it is movable If the discharge completion time (or time) of the desired capacity is the desired discharge completion time (or time) of the second user Ub, it is determined that the movement is possible (f6). The charge completion time (or time) of the desired capacity is the second user Ub. If the desired charge completion time (or within the time) is determined to be movable

Here, the desired trading capacity is the amount of power that at least one of the first user Ua and the second user Ub desires to buy and sell. When the desired trading capacity matches and the contract is established, the desired trading capacity is the contracted power. Determined as a quantity.

The first user Ua may be able to specify the desired power sale capacity on a setting screen (not shown) in advance or at the time of contract. The desired power sale capacity designated by the first user Ua is stored for each user in the power sale condition storage unit 140 of FIG. In addition, a desired power selling price may be specified.

In addition, the second user Ub specifies the power purchase desired capacity range, the power purchase desired price (or the power purchase desired price (point conversion, etc.)), the desired discharge completion time (or within time), etc. It may be specified on a setting screen (not shown). Information designated by the second user Ub is stored for each user in the power purchase condition storage unit 142 of FIG. As shown in the figure, one user may specify a plurality of conditions.

The power purchase desired price and the power purchase desired price are the amount paid or the unit price of the incentive paid by the second user Ub as the price for receiving power supply from the first user Ua. As shown in FIG. 23 (b), a certain second user Ub may separately set a power purchase amount by money and a power purchase amount by incentive as power purchase conditions. Alternatively, as the power purchase condition, a different unit price may be set for each range of the power purchase amount.

The power selling desired price is an amount received as a consideration for the first user Ua to supply power to the second user Ub or a desired unit price of incentive (not shown). Although not shown, a certain first user Ua may set a different unit price for each range of power sales amount as a power sale condition. In addition, since the incentive has different conditions for each store, a different desired unit price may be set for each store.

In the power sale condition storage unit 140 in FIG. 23A, the power sale conditions (for example, desired power sale capacity (kWh), desired power sale price (yen / kWh)) of the first user Ua are associated with the user ID. Remembered.

The first user Ua may sell power to a plurality of second users Ub, and the desired power sale capacity indicates the maximum value of the total power sold to the plurality of second users Ub. On the screen where the first user Ua specifies the desired power sale capacity, the current storage capacity and the rated capacity of the storage battery of the first user Ua may be displayed and presented to the first user Ua. Alternatively, the amount of power required by the first user Ua is automatically calculated from the rated capacity of the storage battery of the first user Ua based on the current storage capacity or the history information of the power consumption of the first user Ua. It may be displayed on the screen for designating the desired power sale capacity and presented to the first user Ua.

Furthermore, the desired power sale capacity and the dischargeable capacity may be compared, and the result may be presented to the first user Ua to prompt the user to change the desired power sale capacity. For example, when the desired power sale capacity is larger than the dischargeable capacity, it may be urged to change the desired power sale capacity to be smaller than the dischargeable capacity. On the contrary, when the desired power sale capacity is smaller than the dischargeable capacity, the fact may be notified, and further, it may be notified that the desired power sale capacity can be increased.

Also, the second user Ub may purchase power from a plurality of first users Ua, and the power purchase desired capacity indicates the maximum value of the total power purchased from the plurality of first users Ua. On the screen where the second user Ub specifies the desired power purchase capacity, the current storage capacity and the rated capacity of the storage battery of the second user Ub may be displayed and presented to the second user Ub. Alternatively, the amount of power required by the second user Ub is automatically calculated from the rated capacity of the storage battery of the second user Ub based on the current storage capacity or the history information of the power consumption of the second user Ub. May be displayed on a screen for designating the desired power purchase capacity and presented to the second user Ub.

Also, the desired power purchase capacity may be compared with the chargeable capacity, and the result may be presented to the second user Ub to prompt the user to change the desired power purchase capacity. For example, when the desired power purchase capacity is larger than the chargeable capacity, it may be urged to change the desired power purchase capacity to be smaller than the chargeable capacity. Conversely, when the desired power purchase capacity is smaller than the chargeable capacity, a notification to that effect may be given and further the power purchase desired capacity may be increased.

The power purchase condition of the second user Ub may or may not be displayed on the first user terminal 50 of the first user Ua. Alternatively, it may be possible for the user to specify whether or not the information is publicly available. The conditions designated as openable may be displayed on the first user terminal 50 of the first user Ua, and the first user Ua may select and contract from the conditions.

The dischargeable capacity is exemplified below, but is not limited thereto.
(G1) Actual power storage amount of the storage battery of the first user Ua at that time (g2) Dischargeable capacity estimated from the power storage amount in consideration of the self power consumption of the first user Ua (g3) Trading of the first user Ua Desired capacity (may be larger than actual power storage)

In (g3), when the desired trading capacity (or contract power amount) is larger than the actual stored power amount, the contract power amount may be discharged in total while repeating discharging and charging a plurality of times. In addition, when the discharge amount per unit time calculated by Equation (1) described later is small and it takes time to discharge the desired trading capacity (or contract power amount), the discharge is performed in multiple times. The storage battery can also be charged between discharges. By doing so, the dischargeable capacity can be increased.

Although chargeable capacity is illustrated below, it is not limited to these.
(H1) Actual free capacity of the storage battery of the second user Ub at that time (h2) Rechargeable capacity estimated from the amount of stored electricity in consideration of the first user Ua's own power consumption (h3) Trading of the second user Ub Desired capacity (may be larger than actual free capacity)
In the case of (h3), the contract power amount may be charged in total while repeating discharging and charging a plurality of times.

The dischargeable capacity and the chargeable capacity are stored in the storage battery state information storage unit 114 of FIG.

Here, it is conceivable that the storage battery of the first user Ua or the second user Ub supplies power to the load of each user in addition to charging / discharging the power system 40. The amount of power consumed by the load per unit time is called private power consumption. Therefore, there is a possibility that the dischargeable capacity cannot secure the power capacity (referred to as the charged amount) stored in the storage battery of the first user Ua. On the other hand, there is a possibility that the chargeable capacity can be increased more than the free capacity of the storage battery of the second user Ub.

Therefore, this embodiment has a configuration for estimating the dischargeable capacity or the chargeable capacity in consideration of the user's own power consumption.

The receiving part 104 receives the storage battery information which shows the rated output and storage amount of the storage battery of the first user Ua.
The control unit 130 estimates the dischargeable capacity of the first storage battery based on the storage battery information of the storage battery of the first user Ua. That is, the control unit 130 further has a function of estimation means (not shown).
The display unit 108 displays the estimated dischargeable capacity of the storage battery of the first user Ua on at least one of the first user terminal 50 and the second user terminal 60 (for example, the power transaction screen 230 in FIG. 13).

Also, the estimated dischargeable capacity may be used by the control unit 130 to determine whether or not power transfer is possible.

Hereinafter, a method for estimating the dischargeable capacity will be described.
The amount of discharge that can actually be discharged per unit time from the storage battery of the first user Ua to the power system 40 is calculated by the following equation (1).
Discharge amount per unit time = Rated output of storage battery-Private power consumption ・・ Expression (1)

When the discharge time when discharging at the rated output from the storage amount of the storage battery at the time of contract is multiplied by the discharge amount per unit time of Equation (1), the dischargeable capacity is calculated by the following Equation (2).
Dischargeable capacity = Charge amount x (Rated output-Private power consumption) / Rated output ・・ Formula (2)

The receiving unit 104 receives, from the HEMS 26 or the EMS 24, the self-power consumption per unit time of the storage battery of the first user Ua and the storage battery information regarding the rated output of the storage battery.
The storage battery information includes at least the private power consumption per unit time of the storage battery and the rated output of the storage battery.
In addition, the personal power consumption per unit time accumulates historical information of the personal power consumption of the first user Ua, and calculates, for example, an average power consumption for each time zone of the month. Can be used.
And the control part 130 calculates a dischargeable capacity | capacitance using the said Formula (2).

The dischargeable capacity calculated in this way is stored in the storage battery state information storage unit 114 of FIG. 6, and is further read by the display unit 108 and displayed on the dischargeable capacity display unit 232 of the power transaction screen 230 of FIG. 13. May be displayed. As described above, the dischargeable capacity displays at least one of a plurality of values (g1) to (g3). A plurality of values may be displayed. In that case, it is preferable to display together information indicating which value is displayed.

The discharge completion time (or time) in (f5) and the charge completion time (or time) in (f6) will be described below.
The discharge (charge) completion time is (i1) when each user sets the start time of discharge (or charge), (i2) when discharge (or charge) starts automatically after the contract is established, (i3) charge When the discharge is performed in a plurality of times, the calculation method varies depending on the discharge.
First, the controller 130 calculates a time required for discharging (or charging) when discharging (or charging) is continuously performed. That is, the control unit 130 corresponds to a calculation unit.

Also, the chargeable capacity can be estimated as well as the dischargeable capacity. Detailed description is omitted here.

The receiving unit 104 receives information indicating at least one of the discharge capacity per unit time of the storage battery of the first user Ua and the charge capacity per unit time of the storage battery of the second user Ub.
Based on information indicating at least one of the storage capacity of the storage battery of the first user Ua and the storage capacity of the storage battery of the second user Ub, the control unit 130 completes the discharge of the contract power amount by the storage battery of the first user Ua. At least one of the required discharge time and the required charge time required for the storage battery of the second user Ub to complete the charging of the contracted electric energy.

The discharge (or charge) capacity per unit time of the storage battery differs depending on whether or not there is power that is consumed in-house. For example, when there is no self-consumed power, the rated output of the storage battery is the discharge capacity per unit time. When there is power consumed by the house, the discharge capacity per unit time can be obtained from the above equation (1).
As for the charging capacity, for example, the receiving unit 104 acquires information indicating what percentage of the rated current of the storage battery is charged, and based on the information, the control unit 130 determines the charging capacity per unit time. Can be calculated.

Then, the control unit 130 divides the contract power amount by the calculated discharge (or charge) capacity per unit time to calculate the time required for discharge (or charge). The calculated required time may be stored in the charge / discharge information storage unit 122.

In the case of (i1), the control unit 130 calculates a scheduled discharge (or charge) completion time based on the start time and the required time set by the user. In the case of (i2), the control unit 130 calculates a scheduled discharge (or charge) completion time based on the time when the charge / discharge control is started and the required time.

In the case of (i3), the control unit 130 creates a time schedule for performing discharge and charge according to the following charge / discharge control conditions, and the scheduled execution time of discharge (or charge) reaches the required time according to the schedule. The time is calculated and set as the scheduled discharge (or charge) completion time.

The conditions for charge / discharge control of the storage battery are exemplified below, but are not limited thereto. A plurality of conditions may be combined (logical sum or logical product).
(J1) When the storage amount of the storage battery on the discharge side is less than the first threshold, the discharge of the storage battery on the discharge side is stopped and charged (j2) When the unit price of the electric power system 40 is lower than the first predetermined amount Discharging the storage battery on the discharge side and charging (j3) If the power unit price of the power system 40 is higher than the second predetermined amount, discharge on the storage battery on the discharge side (j4) of the storage battery on the discharge side If the amount of discharge per unit time (rated output of the storage battery-self-consumption power) is less than the second threshold (or if the self-consumption power is greater than or equal to a predetermined value), the discharge-side storage battery stops discharging and charges ( j5) Discharging with the storage battery on the discharge side and charging with the storage battery on the charge side (based on the contract) during the time zone specified by the second user Ub (or the first user Ua) (j6) Empty storage battery on the charge side When the capacity is less than the third threshold, the storage battery on the charging side It stops charging, when the supply to the load 38 (discharge) to (j7) space on the charge side of the battery is equal to or greater than the fourth threshold value, for charging the charging side of the battery

In addition, after the contract, there may be a case where charging / discharging for the contract power amount cannot be performed due to problems such as a storage battery of the first user Ua or the second user Ub.
Therefore, when it is determined that the movement of the contract power amount has been completed, the control unit 130 displays information indicating an incentive determined based on the contract conditions and the actual discharge contents of the storage battery, in the first user terminal 50. Output to.

Although the determination method of an incentive is illustrated below, it is not limited to these. A plurality of the following may be combined.
(K1) If the amount of discharge up to a predetermined time (such as a scheduled discharge completion time or a desired discharge completion time) is less than the contract power amount, the incentive is reduced according to the shortage.
(K2) If the discharge completion time is delayed from a predetermined time (such as a scheduled discharge completion time or a desired discharge completion time), the incentive is reduced according to the delay time.

The method for outputting the information indicating the incentive is the same as in the above embodiment, and is displayed on the transaction confirmation screen 290 (FIG. 22B), pop-up display, notification in the notification column, banner display, batch display, predetermined destination Information may be output by at least one or a combination of a variety of output methods, such as sending messages to, sound output, and vibration output.

According to the present embodiment, the same effects as those of the above embodiment can be obtained.
Furthermore, as described above, according to the present embodiment, it is determined whether or not power transfer is possible. For example, when the transfer is possible, the display unit 108 displays a screen for establishing a contract. Therefore, when it is determined that the power transfer is not possible, the contract cannot be advanced, so that a contract that cannot be executed is not concluded.

In addition, since the user can calculate the range of the amount of power that can be charged / discharged by each user's storage battery and the time required for charging / discharging and present it to the user at the time of the contract, the user knows in advance the travel time of the power to be bought and sold. be able to. Furthermore, since the current power transfer status between the storage batteries is displayed while being updated in real time, each user can know the power transfer status between the storage batteries in real time. Since it may take time to charge and discharge the storage battery, it is convenient to check the status of the storage battery each time.

As mentioned above, although embodiment of this invention was described with reference to drawings, these are the illustrations of this invention, Various structures other than the above are also employable.
For example, a configuration in which the second user Ub consumes the power purchased from the first user Ua by the load 38 instead of charging the storage battery will be described below.
In this configuration, the control unit 130 of the server 10 does not issue a charge control instruction to the second power system 30 of the second user Ub. Then, the second user Ub transmits information on the contract power amount purchased from the first user Ua to the power company. The server of the electric power company subtracts the contract power amount from the power consumption amount of the second user Ub collected from the smart meter SMb, and calculates the electricity bill based on the result.

In addition, instead of receiving the storage battery charge amount of the second power system 30, the receiving unit 104 receives the measured value of the smart meter SMb after the first power system 20 starts discharging after the contract is established, The charge / discharge amount storage unit 124 stores the charge amount measurement value. And the control part 130 calculates the integrated value of a measured value, and continues integration until an integrated value becomes contract electric energy. The control unit 130 stores the calculated integrated value in the charge / discharge amount information storage unit 126 as a charged power amount. The display unit 108 reads the charged power amount from the charge / discharge amount information storage unit 126 and displays the screen.

When the integrated value becomes equal to the contract power amount, the determination unit 106 has completed the transfer of the contract power amount from the first power system 20 of the first user Ua to the second power system 30 of the second user Ub. You may judge.

While the present invention has been described with reference to the embodiments and examples, the present invention is not limited to the above embodiments and examples. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
In addition, when acquiring and using the information regarding a user in this invention, this shall be done legally.
