DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] An embodiment for carrying out the present disclosure will be described with reference to the drawings. Note that the embodiment described below is an exemplary embodiment assumed when carrying out the present disclosure. Therefore, the scope of the present disclosure is not limited to the embodiment exemplified below.

[0009] A: First embodiment 1 is a block diagram of a power system 100 according to a first embodiment. The power system 100 according to the first embodiment is a system for managing power in a specific area (hereinafter referred to as a "target area A1"), such as a mountainous area or an isolated island, and includes an independent grid 11, a power storage system 12, and a management system 20.

[0010] The independent system 11 is a small-scale power system (microgrid) installed in the target area A1. Specifically, the independent system 11 is a power distribution system for supplying power to business facilities or consumers such as general households in the target area A1. The independent system 11 is installed independent of the main power system 91. That is, the independent system 11 is in a state of being disconnected from the power system 91. The independent system 11 is operated, for example, by a local government. However, the independent system 11 may also be operated by a private operator such as a power transmission and distribution operator.

[0011] The power system 91 is a power distribution system installed in an area outside the target area A1 (hereinafter referred to as "external area A2"). Specifically, the power system 91 is a wide-area power distribution system including large-scale power generation facilities such as thermal power plants or nuclear power plants. The external area A2 is, for example, an urban area where many consumers are located. As described above, since the independent system 11 is cut off from the power system 91, there is a possibility that the independent system 11 will experience a power shortage.

[0012] The power storage system 12 is one or more storage batteries connected to the independent system 11. For example, a stationary power storage facility equipped with a plurality of storage batteries is used as the power storage system 12. The power storage system 12 is capable of charging with power and supplying (i.e. discharging) the power to the independent system 11. The power storage system 12 may be understood as an element constituting the independent system 11.

[0013] The management system 20 is a computer system (EMS: Energy Management System) for managing the power of the independent system 11. Specifically, the management system 20 controls the power that the power storage system 12 exchanges with the independent system 11. For example, the management system 20 controls the charging and discharging of the power storage system 12 so that the power of a specific point in the independent system 11 is maintained at a target value. That is, when the power of the specific point is below the target value, the management system 20 supplies power to the independent system 11 by discharging the power storage system 12. On the other hand, when the power of the specific point is above the target value, the management system 20 charges the power storage system 12 with the power supplied from the independent system 11.

[0014] In the above description, the control of the power storage system 12 by the management system 20 has been exemplified, but the management system 20 also controls power equipment other than the power storage system 12. The power equipment is a power resource that exchanges power with the independent grid 11. For example, examples of the power equipment include a hydrogen production device that produces hydrogen using power supplied from the independent grid 11, and a distributed power generation facility that generates power using renewable energy such as solar power or wind power. The power equipment exemplified above may be understood as elements that constitute the independent grid 11.

[0015] A plurality of users U are located in the target area A1. The plurality of users U are, for example, residents who live in the target area A1 or workers who commute to the target area A1. Each user U can travel using an electric vehicle (EV) 30 equipped with a storage battery 31. The electric vehicle 30 is a mobile body that can run using an electric motor powered by the storage battery 31. The storage battery 31 is a secondary battery that can charge and discharge power.

[0016] Each user U can use an information device 40. The information device 40 is a portable terminal device such as a smartphone or tablet terminal owned by the user U, or a route guidance device (car navigation system) installed in the electric vehicle 30. The route guidance device may be either built into the electric vehicle 30 or detachably installed in the electric vehicle 30.

[0017] Each user U can move inside and outside the target area A1. For example, a user U residing in the target area A1 uses an electric vehicle 30 to travel between his / her home in the target area A1 and his / her workplace in an external area A2 on a daily basis. A user U residing in the external area A2 uses an electric vehicle 30 to travel between his / her home in the external area A2 and his / her workplace in the target area A1 on a daily basis.

[0018] During the period in which the electric vehicle 30 is located in the external area A2, the user U can charge the storage battery 31 of the electric vehicle 30 with power supplied from a power grid 91 in the external area A2. Furthermore, during the period in which the electric vehicle 30 is located in the target area A1, the user U can provide the power stored in the storage battery 31 to the power storage system 12. That is, the power storage system 12 can store the power supplied from the electric vehicle 30. Furthermore, the power storage system 12 supplies the power provided by the electric vehicle 30 to the independent grid 11.

[0019] As described above, the independent system 11 is independent from the power system 91, but can indirectly receive power from the power system 91 via the electric vehicle 30 traveling between the target area A1 and the external area A2. That is, power from the power system 91 is transported to the independent system 11 by the electric vehicle 30. That is, each user U can provide power to the power storage system 12 using the electric vehicle 30 (hereinafter referred to as "power provision"). Therefore, according to the first embodiment, the possibility of a power shortage in the independent system 11 can be reduced.

[0020] Each user U is not a business operator whose daily business is to provide electric power, but an ordinary resident who travels between the target area A1 and the external area A2. That is, when the user U travels between the target area A1 and the external area A2 in the electric vehicle 30 for his / her own purpose, the transfer of electric power from the power grid 91 to the independent grid 11 is realized incidentally. According to the above embodiment, the cost of securing electric power for the independent grid 11 can be reduced compared to the case where electric power is requested to a specialized business operator fixedly designated by a prior plan.

[0021] The management system 20 of the first embodiment is a system for smoothly operating power supply using an electric vehicle 30. Fig. 2 is a block diagram illustrating an example of the configuration of the management system 20. As illustrated in Fig. 2, the management system 20 includes a control device 21, a storage device 22, and a communication device 23. The management system 20 may be realized as a single device, or may be realized as a plurality of devices configured separately from each other.

[0022] The control device 21 is composed of one or more processors that control each element of the management system 20. Specifically, the control device 21 is composed of one or more types of processors, such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), or an ASIC (Application Specific Integrated Circuit).

[0023] 1, the communication device 23 communicates with each information device 40 via a communication network 92 such as the Internet. Note that the communication device 23, which is separate from the management system 20, may be connected to the management system 20 by wire or wirelessly. The communication device 23 also communicates with the power storage system 12 via the communication network 92 such as a dedicated line.

[0024] 2 is a single or multiple memories that store programs executed by the control device 21 and data used by the control device 21. The storage device 22 is configured with a known recording medium such as a magnetic recording medium or a semiconductor recording medium. The storage device 22 may be configured with a combination of multiple types of recording media. A portable recording medium that is detachably attached to the management system 20 may be used as the storage device 22.

[0025] The storage device 22 stores registration data D for each of a plurality of users U. For example, the registration data D of each user U is stored in the storage device 22 through a prior registration process performed by the user U. FIG. 3 is a schematic diagram of the registration data D. As illustrated in FIG. 3, the registration data D includes identification information D1, destination information D2, and payment information D3. The identification information D1 is a code string for identifying the user U.

[0026] The destination information D2 is information that indicates the destination of information transmitted from the management system 20. Specifically, information for identifying the information device 40 owned by the user U (for example, an IP address) is registered as the destination information D2.

[0027] The payment information D3 is information for paying the user U the price for the provision of electricity using the electric vehicle 30. For example, information for identifying the payee of the price, such as a bank account number or electronic money account information, is registered as the payment information D3.

[0028] 4 is a block diagram illustrating an example of a functional configuration of the management system 20. The control device 21 executes a program stored in the storage device 22 to realize a plurality of functions (an information processing unit 211, a price processing unit 212) for smoothly operating the supply of electric power using the electric vehicle 30.

[0029] The information processing unit 211 transmits a supply request R to each of the multiple users U. Specifically, the information processing unit 211 transmits the supply request R via the communication device 23 to the information device 40 specified by the destination information D2 of the registration data D as the destination. The supply request R is a message requesting each user U to provide power.

[0030] Fig. 5 is a schematic diagram of a supply request R. As illustrated in Fig. 5, the supply request R in the first embodiment includes power information X. The power information X is information that represents the status of power in the independent grid 11. Specifically, the power information X includes a target power amount X1, a remaining charge amount X2, a supply deadline X3, and a purchase price X4.

[0031] The target energy amount X1 is a target value of the energy amount to be secured in the independent grid 11. The remaining charge amount X2 is the amount of charge remaining in the power storage system 12. The supply deadline X3 is a deadline for the supply of electricity by the user U. For example, a specific date and time is specified as the supply deadline X3. The purchase price X4 is a trading price for electricity supplied using the electric vehicle 30.

[0032] 4 pays the consideration to a user U who actually provides power from the electric vehicle 30 to the power storage system 12 in response to the supply request R, among multiple users U. Specifically, the consideration processing unit 212 executes a payment process of the consideration to a payee represented by the payment information D3.

[0033] Fig. 6 is a block diagram illustrating an example of the configuration of an information device 40. As illustrated in Fig. 6, the information device 40 includes a control device 41, a storage device 42, a communication device 43, a display device 44, and an operation device 45. The information device 40 may be realized as a single device, or may be realized as a plurality of devices configured separately from each other.

[0034] The control device 41 is composed of one or more processors that control each element of the information device 40. For example, the control device 41 is composed of one or more types of processors such as a CPU, a GPU, a DSP, an FPGA, or an ASIC.

[0035] The storage device 42 is one or more memories that store the programs executed by the control device 41 and various data used by the control device 41. The storage device 42 is configured with a known recording medium such as a magnetic recording medium or a semiconductor recording medium. The storage device 42 may be configured with a combination of multiple types of recording media. Also, a portable recording medium that is detachable from the information device 40 may be used as the storage device 42.

[0036] The communication device 43 communicates with the management system 20 via the communication network 92. For example, the communication device 43 receives a provision request R transmitted from the management system 20. Note that the communication device 43, which is separate from the information device 40, may be connected to the information device 40 by wire or wirelessly.

[0037] The display device 44 displays an image under the control of the control device 41. The display device 44 is configured with a display panel such as a liquid crystal panel or an organic EL (Electroluminescence) panel. The operation device 45 is an input device that receives instructions from the user U. The operation device 45 is, for example, an operator operated by the user U, or a touch panel that detects contact by the user U. Note that the display device 44 or the operation device 45, which are separate from the information device 40, may be connected to the information device 40 by wire or wirelessly.

[0038] The control device 41 displays the confirmation screen 50 of FIG. 7 on the display device 44 in response to the provision request R received by the communication device 43 from the management system 20. As illustrated in FIG. 7, the confirmation screen 50 includes a notification area 51 and an operation area 52.

[0039] The notification area 51 displays information related to a request for power provision using the electric vehicle 30. Specifically, the notification area 51 displays power information X (target power amount X1, remaining charge amount X2, provision deadline X3, and purchase price X4) included in the power provision request R. By referring to the power information X displayed in the notification area 51, the user U can determine whether or not to accept the power provision.

[0040] The operation area 52 is an area where the user U receives an instruction as to whether or not to accept the provision of power. Specifically, an operator 521 and an operator 522 are displayed in the operation area 52. The operator 521 receives a response from the user U that the provision of power will be accepted. The operator 522 receives a response from the user U that the provision of power will not be accepted. As illustrated in FIG. 6, the communication device 43 transmits response information Q representing the response of the user U to the operation area 52 to the management system 20. The response information Q is information representing the acceptance / rejection of the provision of power by the user U.

[0041] 8 is a flowchart of a process (hereinafter referred to as a "management process") executed by the control device 21 of the management system 20. The management process is repeated, for example, at a predetermined cycle.

[0042] When the management process is started, the control device 21 (information processing unit 211) sets a target power amount X1 (Sa1). Specifically, the control device 21 sets the target power amount X1 according to a predicted value of the amount of power used in the independent system 11 (hereinafter referred to as "predicted usage amount"). For example, the control device 21 calculates the predicted usage amount according to various information that affects the amount of power usage in the target area A1, such as the current day of the week, time period (morning / afternoon / night), weather (sunny / cloudy / rainy / snow), temperature, season (spring / summer / autumn / winter), etc., and sets the target power amount X1 corresponding to the predicted usage amount. Any known technology is adopted to set the target power amount X1 (or the predicted usage amount).

[0043] The control device 21 (information processing unit 211) sets the remaining charge X2 (Sa2). Specifically, the control device 21 receives charging information transmitted from the power storage system 12 by the communication device 23, and sets the remaining charge X2 by analyzing the charging information. The charging information is, for example, a State Of Charge (SOC) that indicates the charging state of the power storage system 12.

[0044] The control device 21 (information processing unit 211) sets the provision deadline X3 (Sa3). Specifically, the control device 21 sets the provision deadline X3 in response to an instruction from an administrator to the management system 20. The provision deadline X3 may be set for each predetermined period set in advance.

[0045] The control device 21 (information processing unit 211) sets the purchase price X4 (Sa4). Specifically, the control device 21 sets the purchase price X4 according to the target energy X1, the remaining charge X2, the supply deadline X3, and the response status to the supply request R. For example, the control device 21 increases the purchase price X4 as the target energy X1 increases. The control device 21 increases the purchase price X4 as the remaining charge X2 decreases. The control device 21 increases the purchase price X4 as the supply deadline X3 approaches (the time remaining until the supply deadline X3 is shorter). With the above configuration, the purchase price X4 can be appropriately set according to the power status in the independent system 11.

[0046] The response status to the supply request R is, for example, the status of responses (accepted / rejected / no reply) by multiple users U to whom the supply request R was sent. For example, the ratio of users U who responded to accept the electricity supply among the multiple users U (hereinafter referred to as the "contract ratio") is used as an index of the response status. The control device 21 receives the response information Q transmitted from each information device 40 by the communication device 23, and calculates the contract ratio according to the response information Q of each information device 40. The lower the contract ratio (i.e., the fewer users U who accept the electricity supply), the more the control device 21 increases the purchase price X4.

[0047] As can be understood from the above explanation, the purchase price X4 is set according to the degree of tightness of the amount of power in the independent system 11. That is, the target amount of power X1, the remaining charge amount X2, the supply deadline X3, and the response status to the supply request R are used as indicators representing the degree of tightness of the amount of power in the independent system 11. By increasing the purchase price X4 as the possibility of tightness of the amount of power in the independent system 11 increases, it is possible to encourage a large number of users U to accept the supply of power. The order of steps Sa1 to Sa4 may be changed as desired. Also, the purchase price X4 may be a fixed value.

[0048] The control device 21 (information processing unit 211) transmits a supply request R including the above-described power information X (target power amount X1, remaining charge X2, supply deadline X3, purchase price X4) from the communication device 23 to the information device 40 of each user U (Sa5).

[0049] 9 is a flowchart of a process (hereinafter referred to as a "response process") executed by the control device 41 of each information device 40. The response process is repeated, for example, at a predetermined cycle.

[0050] The control device 41 waits until the communication device 43 receives the supply request R transmitted from the management system 20 (Sb1: N0). Upon receiving the supply request R (Sb1: YES), the control device 41 displays the confirmation screen 50 of FIG. 7 in response to the supply request R on the display device 44 (Sb2). Specifically, the power information X (target power amount X1, remaining charge amount X2, supply deadline X3, purchase price X4) included in the supply request R is displayed on the confirmation screen 50. The user U refers to the power information X displayed in the notification area 51 to determine whether or not to accept the supply of power.

[0051] The user U operates either the operator 521 or the operator 522 in the operation area 52 depending on the result of the determination. The control device 41 accepts the operation on the operation area 52 (Sb3). The control device 41 transmits response information Q representing a response from the user U to the operation area 52 from the communication device 43 to the management system 20 (Sb4).

[0052] 8, when a provision request R is transmitted to the information device 40 of each user U (Sa5), the control device 21 (information processing unit 211) of the management system 20 receives, via the communication device 23, response information Q transmitted from each information device 40 in response to the provision request R (Sa6). The response information Q received from each information device 40 is used to analyze the response status (acceptance ratio) to the provision request R in the next management process.

[0053] The user U who has responded to accept the request for power supply drives the electric vehicle 30 to the vicinity of the power storage system 12 and connects the electric vehicle 30 to the power storage system 12 to supply power from the storage battery 31 to the power storage system 12. When power supply to the power storage system 12 is completed, the control device 41 transmits a supply notification N from the communication device 43 to the management system 20 (Sb5). The supply notification N in the first embodiment includes the amount of power provided from the electric vehicle 30 to the power storage system 12 (hereinafter referred to as the "power supply amount") E1. The power supply amount E1 may be notified to the information device 40 from the power storage system 12, for example, or may be instructed by the user U by operating the operation device 45.

[0054] 8, the control device 21 of the management system 20 receives the provision notification N transmitted from each information device 40 by the communication device 23 (Sa7). The control device 21 (the compensation processing unit 212) executes a payment process for each information device 40 that transmitted the provision notification N (Sa8, Sa9). The payment process is a process for paying compensation to the user U who executed the power provision.

[0055] Specifically, the control device 21 sets the price of the compensation (hereinafter referred to as "compensation") P to be paid to the user U (Sa8). Specifically, the control device 21 sets the compensation P according to the amount of power provided E1 and the purchase price X4. For example, the compensation P is calculated by multiplying the amount of power provided E1 and the purchase price X4.

[0056] The control device 21 pays the consideration amount P to the payee represented by the payment information D3 of each user U (Sa9). For example, the control device 21 transmits a transfer request for the consideration amount P to an account server that manages the account of the user U. Through the payment process described above, the user U can receive the consideration for the provision of electricity.

[0057] As described above, in the first embodiment, the supply request R including the power information X of the independent system 11 is transmitted to a plurality of users U, and a compensation is paid to the user U among the plurality of users U who has executed the power supply in response to the supply request R. According to the above configuration, for example, users U (e.g., residents or workers) located in the target area A1 in which the independent system 11 is installed can share the power supply to the independent system 11. Therefore, the cost of securing power for the independent system 11 can be reduced compared to the case where the supply of power is requested from a specialized business operator fixedly designated by a prior plan. Moreover, as a result of the compensation being paid for the power supply, an incentive to supply power is given to each user U. Therefore, the supply of power by a large number of users U can be effectively promoted.

[0058] In particular, in the first embodiment, the electric vehicle 30 used by the user U is used to provide electric power to the power storage system 12. For example, the user U can provide electric power to the power storage system 12 by stopping by the power storage system 12 during travel using the electric vehicle 30. That is, the user U can easily provide electric power in his / her daily life. Therefore, electric power can be expected to be provided by a large number of users U.

[0059] B: Second embodiment A second embodiment of the present disclosure will be described. Note that, for elements having the same functions as those in the first embodiment in each of the following exemplary aspects, the same reference numerals as those in the first embodiment will be used, and detailed descriptions of each will be omitted as appropriate.

[0060] Fig. 10 is a schematic diagram of a provision notification N transmitted from an information device 40 to a management system 20 in the second embodiment. As illustrated in Fig. 10, the provision notification N in the second embodiment includes a power consumption amount E2 in addition to the power provision amount E1 similar to the first embodiment.

[0061] The power consumption E2 is the amount of power consumed by the electric vehicle 30 in traveling for providing power. For example, the control device 41 acquires, as the power consumption E2, the amount of power consumed by the electric vehicle 30 from when the user U operates the operation button 521 until the provision of power to the power storage system 12 is completed. The power consumption E2 is notified to the information device 40 from the electric vehicle 30, for example.

[0062] In the management process, the control device 21 of the first embodiment sets the consideration P according to the amount of power provided E1 and the purchase price X4 (Sa8). The control device 21 (the consideration processing unit 212) of the second embodiment sets the consideration P by taking into account the amount of power consumed E2 in addition to the amount of power provided E1 and the purchase price X4. Specifically, the control device 21 calculates the consideration P by multiplying the sum of the amount of power provided E1 and the amount of power consumed E2 by the purchase price X4.

[0063] That is, the control device 21 of the second embodiment sets the compensation amount P according to the amount of power provided E1 and the amount of power consumed E2. The process for paying the compensation amount P (Sa9) is similar to that of the first embodiment. As can be understood from the above explanation, in addition to paying the compensation for the power provision to the user U, the user U is compensated with a value equivalent to the power consumed for the movement required for the power provision.

[0064] The second embodiment also achieves the same effects as the first embodiment. Furthermore, in the second embodiment, in addition to the power provided from the electric vehicle 30 to the power storage system 12 (power provision amount E1), the power consumed by the electric vehicle 30 in traveling to provide power (power consumption amount E2) is also reflected in the compensation for the user U. Therefore, an effective incentive can be given to many users U to travel by electric vehicle 30 and provide power to the power storage system 12.

[0065] C: Third embodiment 11 is a schematic diagram of a supply request R in the third embodiment. The supply request R in the third embodiment includes situation information Y in addition to power information X similar to that in the first embodiment.

[0066] As in the first embodiment, the control device 21 (information processing unit 211) of the management system 20 in the third embodiment receives response information Q indicating acceptance / rejection of the power supply from the information device 40 of each user U (Sa6). The status information Y included in the supply request R is information indicating the status of the response by each user U. Specifically, the status information Y is information indicating whether the power supply has been accepted for each user U. For example, information indicating acceptance of the power supply, refusal of the power supply, and non-receipt of a response (no reply) is generated as the status information Y.

[0067] The control device 41 of the information device 40 that has received the supply request R displays the confirmation screen 50 of FIG. 12 in response to the supply request R on the display device 44 (Sb2). As illustrated in FIG. 12, the confirmation screen 50 of the third embodiment includes a response area 53 in addition to the notification area 51 and operation area 52 similar to those of the first embodiment. In the response area 53, the status of the response regarding the power supply is displayed for each of the multiple users U. Specifically, the control device 41 displays acceptance of the power supply, refusal of the power supply, and no response for each user U using different symbols. In other words, the status of the response regarding the power supply is displayed in a format that does not identify each individual user U. The users U can visually check the status of the responses regarding the power supply (for example, the number of users U who have accepted the power supply).

[0068] The third embodiment also achieves the same effects as the first embodiment. Moreover, in the third embodiment, the response status from each user U regarding the acceptance / rejection of the power supply is notified to multiple users U. Therefore, each user U can determine whether or not to accept the power supply using the electric vehicle 30 while referring to the response status from the other users U.

[0069] D: Variation Specific modified embodiments added to each of the above-mentioned embodiments are exemplified below. Two or more embodiments selected from the following examples may be appropriately combined as long as they are not mutually contradictory.

[0070] (1) In each of the above-described embodiments, the provision request R is sent to all registered users U, but the management system 20 may send the provision request R to only some of the multiple users U.

[0071] 13, for example, the registered data D may include user information D4 in addition to the information (D1 to D3) similar to the above-mentioned forms. The control device 21 (information processing unit 211) transmits a request for provision R to some of the users U whose user information D4 satisfies a specific condition (hereinafter referred to as a "transmission condition") among the multiple users U (Sa5).

[0072] According to the above embodiment, it is possible to reduce the processing load and communication volume of the management system 20, compared to a embodiment in which the provision request R is transmitted to all registered users U. Note that, as specific examples of the relationship between the user information D4 and the transmission condition, the following embodiments A to D are exemplified.

[0073] [Aspect A] The user information D4 in aspect A indicates a time period during which the user U can provide power. The time period is set, for example, for each day of the week or for each month. Each user U can register in advance, as the user information D4, a time period during which the user U is likely to be able to provide power (for example, a time period outside of working hours).

[0074] The transmission condition in mode A is that the time period indicated by the user information D4 overlaps with the period from the present time to the provision deadline X3. That is, the control device 21 (information processing unit 211) transmits the supply request R to some of the users U, among the multiple users U, whose time period indicated by the user information D4 overlaps with the period up to the provision deadline X3. As described above, the supply request R is selectively transmitted to the users U who are highly likely to be able to execute the power supply.

[0075] [Aspect B] The user information D4 in aspect B represents the current location of the user U. For example, the information device 40 of the user U periodically transmits location information to the management system 20. The location information is generated using a positioning technology such as a Global Positioning System (GPS). The control device 21 of the management system 20 updates the user information D4 every time location information is received.

[0076] The transmission condition in aspect B is that the location indicated by the user information D4 is within the target area A1. That is, the control device 21 (information processing unit 211) transmits the supply request R to some of the users U whose locations indicated by the user information D4 are within the target area A1, among the multiple users U. As described above, the supply request R is selectively transmitted to the users U who are located within the target area A1 and have a high possibility of being able to receive power supply.

[0077] [Aspect C] The user information D4 in aspect C represents the movement direction of the user U. For example, location information is periodically transmitted from the information device 40 of the user U to the management system 20. The control device 21 of the management system 20 estimates the movement direction (e.g., a vector) of the user U from the time series of the location information, and updates the user information D4 to the movement direction.

[0078] The transmission condition in aspect C is that the moving direction represented by the user information D4 faces the direction of the power storage system 12. That is, the control device 21 (information processing unit 211) transmits the supply request R to some of the users U, among the multiple users U, whose moving direction represented by the user information D4 faces the direction of the power storage system 12. As described above, the supply request R is selectively transmitted to the users U who are moving toward the power storage system 12 and are highly likely to be able to receive power supply.

[0079] [Aspect D] The user information D4 in aspect D represents the past performance of the user U regarding the provision of electric power. Specifically, the ratio of the number of times the user U actually provided electric power to the number of times the supply request R was transmitted to the user U (hereinafter referred to as the "contract ratio") is registered as the user information D4. For example, the control device 21 updates the user information D4 every time a supply notification N is received.

[0080] The transmission condition in aspect D is that the entrusted ratio represented by the user information D4 is high. That is, the control device 21 (information processing unit 211) transmits the supply request R to a predetermined number of users U among multiple users U, for example, those ranked high in descending order of the entrusted ratio represented by the user information D4. As described above, the supply request R is selectively transmitted to users U who are estimated to have a high possibility of accepting the supply of electricity based on past performance. Note that the supply request R may be transmitted to users U whose entrusted ratio exceeds a predetermined value.

[0081] (2) In each of the above-described forms, an example is given of a form in which the user U indicates whether or not to accept the provision of electricity by operating the operation area 52, but the configuration and processing for accepting whether or not to accept the provision of electricity from the user U are not limited to the above examples.

[0082] For example, in a configuration in which a route guidance device that provides guidance on a route to a destination is used as the information device 40, the setting of the power storage system 12 as a destination or the start of guidance on a route to the power storage system 12 may be regarded as acceptance of the supply of power by the user U. For example, when the power storage system 12 is set as a destination or when guidance on a route to the power storage system 12 starts, the control device 41 transmits response information Q representing the acceptance of the supply of power from the communication device 43 to the management system 20. That is, the operation of the user U on the route guidance device is also used as a response regarding the supply of power. According to the above configuration, the operational load on the user U can be reduced.

[0083] The route guidance device can estimate the arrival time at the destination. In a form in which the route guidance device is used as the information device 40, the arrival time at the power storage system 12 specified as the destination may be notified from the information device 40 to the management system 20 as the time when charging of the power storage system 12 starts.

[0084] (3) In each of the above-described embodiments, the electric vehicle 30 moves close to the power storage system 12 and is connected to the power storage system 12 to provide electric power. However, the method of providing electric power from the electric vehicle 30 to the power storage system 12 is not limited to the above examples. For example, the electric vehicle 30 may be connected to a supply point located in the independent grid 11 away from the power storage system 12, and the electric power of the storage battery 31 may be supplied to the power storage system 12 via a power line connecting the supply point and the power storage system 12.

[0085] As can be understood from the above example, the power consumption E2 in the second embodiment is expressed as the amount of power consumed by the electric vehicle 30 in traveling for providing power. That is, in addition to the amount of power required for the electric vehicle 30 to travel to the vicinity of the power storage system 12, the amount of power required for the electric vehicle 30 to travel to the provision point also corresponds to the power consumption E2.

[0086] (4) In each of the above-described embodiments, a stationary storage system 12 that is fixedly installed has been exemplified, but the embodiment of the storage system 12 is not limited to the above examples. For example, the storage system 12 may be configured by a storage battery 31 of an electric vehicle 30 connected to an independent grid 11. In other words, the storage system 12 may be configured by either a stationary or movable storage battery, or may be configured by both a stationary storage battery and a movable storage battery.

[0087] (5) It is also possible that the compensation P for the provision of electric power is applied to the electricity bill payable by the user U. In other words, the compensation P may be offset from the electricity bill payable by the user U for the use of the independent grid 11.

[0088] (6) In each of the above-mentioned embodiments, the compensation P is calculated by multiplying the amount of power provided E1 (and the amount of power consumed E2) by the purchase price X4, but the method of calculating the compensation P for the power provision is not limited to the above examples. For example, when multiple users U provide power, the control device 21 (compensation processing unit 212) may calculate the compensation P for each user U according to the average value of the amount of power provided E1 for the multiple users U.

[0089] (7) In each of the above-mentioned embodiments, the independent system 11 is disconnected from the power system 91, but the independent system 11 does not need to be permanently disconnected from the power system 91. For example, a configuration is also envisaged in which the independent system 11 is connected to the power system 91 under normal conditions and is disconnected from the power system 91 under specific conditions, such as during a disaster or when the power system 91 is under strain.

[0090] As can be understood from the above explanation, the independent system 11 means a system that has the potential to become independent from the power system 91, and does not need to be in a fixed independent state from the power system 91. For example, the independent system 11 includes an isolated island system, a remote distributed grid, a power system operated in an emergency (emergency operation system), or a power system operated autonomously within a specific premises (in-premises independent system), etc.

[0091] (8) In each of the above-mentioned embodiments, the response status (accepted / rejected / no response) regarding the provision of electricity is displayed for each user U using different symbols (FIG. 12), but the format for displaying the response status of each user U regarding the provision of electricity is not limited to the above examples. For example, the ratio of users U who accepted the provision of electricity, the ratio of users U who rejected the provision of electricity, and the ratio of users U who did not respond may be displayed as numerical values ​​on the display device 44.

[0092] (9) In each of the above embodiments, the electric vehicle 30 used for the user U's commute to work is exemplified as a mobile body, but the mobile body applicable to the present disclosure is not limited to the electric vehicle 30 used by general commuters. For example, various mobile bodies used for any business, such as postal services, home delivery services, water services, gas services, administrative services, mobile stores, home care services, and transportation services, may be used in the present disclosure.

[0093] (10) In each of the above embodiments, an electric vehicle 30 is used to provide power, but the mobile object used to provide power is not limited to the electric vehicle 30. For example, any type of mobile object equipped with a storage battery 31, such as an electric motorcycle (electric scooter), an electrically assisted bicycle, or an electric kickboard, may be used to provide power.

[0094] (11) As described above, the functions of the management system 20 according to each of the above-mentioned embodiments are realized by the cooperation of one or more processors constituting the control device 21 and the program stored in the storage device 22. The above-mentioned programs can be provided in a form stored in a computer-readable recording medium and installed in the computer. The recording medium is, for example, a non-transitory recording medium, and a good example is an optical recording medium (optical disk) such as a CD-ROM, but also includes any known type of recording medium such as a semiconductor recording medium or a magnetic recording medium. Note that the non-transitory recording medium includes any recording medium except for a transient, propagating signal, and does not exclude volatile recording media. In addition, in a configuration in which a distribution device distributes a program via a communication network, the recording medium that stores the program in the distribution device corresponds to the non-transitory recording medium described above.

[0095] E: Notes From the above-described exemplary embodiments, the following configurations can be understood, for example.

[0096] A management system according to one embodiment (embodiment 1) of the present disclosure is a management system that manages electricity from an independent system to which a power storage system is connected, and includes an information processing unit that transmits a request for provision including electricity information of the independent system to a plurality of users who use mobile objects capable of providing electricity to the power storage system, and a compensation processing unit that pays compensation for the provision to users among the plurality of users who have provided electricity from their mobile objects to the power storage system in response to the provision request.

[0097] In the above aspect, a supply request including power information of an independent system is transmitted to a plurality of users, and a compensation is paid to a user among the plurality of users who supplies power in response to the supply request. With the above configuration, for example, residents in an area where an independent system is installed can share the supply of power to the independent system. Therefore, the cost of securing power from the independent system can be reduced compared to a case where power supply is requested from a business operator fixedly designated by a prior plan. Moreover, as a result of a compensation being paid for the supply of power, an incentive to supply power is given to each user. Therefore, power supply by a large number of users can be effectively promoted.

[0098] In a specific example (Aspect 2) of Aspect 1, the power information includes at least one of a target amount of power to be secured in the power storage system, a remaining charge amount of the power storage system, and a time limit for providing power. In the above aspect, each user can determine whether or not to provide power from a mobile object by referring to various information provided as the power information.

[0099] In a specific example (Aspect 3) of Aspect 1 or Aspect 2, the power information includes a purchase price applied to calculation of the compensation. In the above aspect, each user can determine whether or not to provide power from a mobile object by referring to the power price corresponding to the compensation to be paid to the user.

[0100] In a specific example (Aspect 4) of Aspect 3, the information processing unit sets the buyback price according to a target amount of power to be secured in the power storage system, a remaining charge of the power storage system, a deadline for providing power, and a response status to the request for power provision. According to the above aspect, the buyback price can be appropriately set according to the status of power in the independent grid.

[0101] In a specific example (Aspect 5) of any one of Aspects 1 to 4, the compensation processing unit sets the value of the compensation according to the amount of power provided from the mobile body to the power storage system and the amount of power consumed by the mobile body in the movement for providing the power. In the above aspects, in addition to the power provided from the mobile body to the power storage system, the power consumed by the mobile body in the movement for providing the power is also reflected in the compensation for the user. Therefore, it is possible to provide an effective incentive to many users to travel by mobile body to provide power to the power storage system.

[0102] In a specific example (Aspect 6) of any one of Aspects 1 to 5, the moving body is an electric vehicle equipped with a storage battery capable of providing power to the power storage system. In the above aspects, the electric vehicle used by a user is used to provide power to the power storage system. For example, the user can provide power to the power storage system by stopping by the power storage system during travel in the electric vehicle. In other words, the user can easily provide power in the course of daily life. Therefore, power provision by a large number of users can be expected.

[0103] In a specific example (Aspect 7) of any of Aspects 1 to 6, the information processing unit receives response information from each of the multiple users indicating a response regarding whether or not to provide power, and the request for power provision includes status information indicating a status of the response by each of the multiple users. In the above aspects, the multiple users are notified of the response status from each user regarding acceptance / rejection of the power provision. Therefore, each user can determine whether or not to accept the power provision using a mobile object while referring to the response status from the other users.

[0104] In a specific example (Aspect 8) of any one of Aspects 1 to 7, the information processing unit transmits the request for provision to a terminal device owned by the user or a route guidance device installed in the mobile object.

[0105] A power system according to one embodiment (embodiment 9) of the present disclosure includes an independent system to which a power storage system is connected, and a management system that manages the power of the independent system, and the management system includes an information processing unit that transmits a request for provision, including power information of the independent system, to a plurality of users who use mobile objects capable of providing power to the power storage system, and a compensation processing unit that pays compensation for the provision to users among the plurality of users who have provided power from their mobile objects to the power storage system in response to the request for provision.
