Detailed Description

Hereinafter, embodiments will be described with reference to the drawings. In the following description of the drawings, the same or similar portions are denoted by the same or similar reference numerals. However, the drawings are schematic drawings.

[ embodiment ]

(Power management System)

Hereinafter, the power management system of the embodiment will be described. As shown in fig. 1, the power management system 100 includes: a user facility 10, an access space 20, a power management device 30, and a user agent 50 carried by a user 40.

The user facility 10 is an example of a predetermined facility having the solar cell device 11. The solar battery device 11 is an example of a distributed power supply provided in the user facility 10. Further, the solar cell device 11 is an example of a power generation device that generates power by using natural energy. The customer facility 10 may also have an EMS (Energy Management System) 12 that manages the power of the customer facility 10. The EMS12 may also be provided by a cloud service. The EMS12 has at least a function of communicating with the power management apparatus 30. For example, the user facility 10 may be the home of the user 40, or may be an organization (company or school) to which the user 40 belongs. In the case where the user 40 has an electricity selling facility (for example, a facility in which electricity selling of 10kW to 50kW is recognized by the facility), the user facility 10 may include the electricity selling facility. However, the user facility 10 is not limited to this, and may have the solar cell device 11. The solar battery device 11 may be owned by the user 40 or lent to the user 40. In other words, the user 40 may be a subject having a right to use the output power of the solar cell device 11.

Here, the EMS12 communicates with devices (e.g., a distributed power supply such as the solar battery device 11) installed in the consumer facility 10 or with sensors that detect power of devices installed in the consumer facility 10. In this case, the EMS12 may transmit data of the output power output from the solar battery device 11 (hereinafter, referred to as output power data) to the power management device 30. The EMS12 may also communicate with the customer agent 50 to send location information of the customer agent 50 to the power management device 30. The location information of the customer agent 50 may be transmitted directly from the customer agent 50 to the power management device 30.

In an embodiment, the user facility 10 may have an electrical storage device 13 and a charging station 14. The power storage device 13 is a device that stores electric power. The power storage device 13 may store surplus power obtained by subtracting power consumption of the customer facility 10 from power output from the solar cell device 11. The power storage device 13 may store the electric power supplied from the electric power system during a time period (e.g., at night) in which the price of the electric power supplied from the electric power system is lower than a threshold value. The charging station 14 is a device that charges an EV (Electric Vehicle) 60. The charging station 14 may charge the EV60 using the electric power output from the solar battery device 11, may charge the EV60 using the electric power supplied from the electric power system, or may charge the EV60 using the electric power output from the electric power storage device 13. The EV60 may be a private car that the user 40 has. When EV60 is charged using the electric power output from solar battery device 11, the electric power used for charging EV60 may be included in the electric power consumed by user facility 10.

The access space 20 is a space to which the user 40 has access possibility. For example, the access space 20 may be a space including a charging station 21 provided at a location different from the user facility 10. The access space 20 may be a space having a distance from the charging station 21 of a threshold value or less (for example, a certain range centered on the charging station 21, a land for a parking lot where the charging station 21 is installed, a land for facilities such as a convenience store where the charging station 21 is installed, or the like). The access space 20 may also be replaced by a charging station 21. The charging station 21 is a device capable of charging the EV 60.

The power management device 30 manages data of output power (the above-mentioned output power data) output from the solar battery device 11. Here, the output power may be power of a backward flow from the utility 10 to the power system. In other words, the output power may be surplus power obtained by subtracting the power consumption of the customer facility 10 from the power output by the solar cell device 11. The power management device 30 executes the fusion process based on the output power data. Details of the power management device 30 will be described later (see fig. 2).

The user 40 is an example of a user having at least the solar cell device 11. The user 40 may also have a user facility 10.

The user medium 50 may be any medium that the user 40 carries. For example, the user agent 50 may be a terminal such as a smart phone or a tablet computer, or may be an IC card such as a credit card or a loyalty card. In the embodiment, the case where the user agent 50 is a smartphone is mainly exemplified. Details of the user agent 50 will be described later (see fig. 4).

Here, the power management apparatus 30 is connected to the customer facility 10 (including the EMS12, the same applies hereinafter) via a network. The power management device 30 may be connected to the charging station 21 via a network. The power management device 30 may be connected to the user agent 50 and the EV60 via a network. Although not particularly limited, the network may include an internet network, and may also include a mobile communication network. The Network may also include a VPN (Virtual Private Network).

(Power management device)

Hereinafter, the power management device of the embodiment will be described. As shown in fig. 2, the power management device 30 includes a communication unit 31, a management unit 32, and a control unit 33.

The communication unit 31 is constituted by a communication module. The communication module can be a wireless communication module conforming to the standards of IEEE802.11a/b/G/n, ZigBee, Wi-SUN, LTE, 5G, 6G and the like, and can also be a wired communication module conforming to the standards of IEEE802.3 and the like.

The communication section 31 receives output power data from the user facility 10. The communication unit 31 may receive the output power data periodically from the consumer appliance 10, or may receive the output power data from the consumer appliance 10 in response to a request from the power management device 30 (control unit 33). The communication unit 31 may receive the output power data from the user facility 10 in response to the approach of the user 40 to the access space 20. The approach to the access space 20 may also be based on a determination by the customer agent 50 that the prompt is to be sent from the customer agent 50 to the power management device 30. Proximity to the access space 20 may also be determined based on location information received from the user media 50. The output power data may include an instantaneous value of the output power (a value of the instantaneous power) or may include an integrated value of the output power (a value of the integrated power amount). The communication unit 31 may transmit data of value (hereinafter referred to as value data) corresponding to power integration described later to the user medium 50.

The user agent 50 is connected to the charging station 21 by the short-range wireless communication, and the communication unit 31 may receive information indicating that the user agent 50 requests the charging station 21 to perform the power fusion from the charging station 21. The Near Field Communication may include RFID (Radio Frequency Identification) such as NFC (Near Field Communication) or the like, and may also include reading of a barcode. In other words, the communication unit 31 is an example of a detection unit that detects the presence of the user 40 in the access space 20 other than the user facility 10.

The management unit 32 is configured by a memory such as a nonvolatile memory and/or a storage medium such as an HDD (Hard disk drive), and stores various kinds of information.

The management unit 32 manages data (hereinafter referred to as management data) shown in fig. 3. The management data includes an ID and an output power. The ID and the output power are examples of the output power data. The ID is information for identifying at least one of the user facility 10 and the solar battery device 11. The management data may also include location information. The location information includes information indicating that there is an access space 20 for the user 40. The location information may also include information indicating the presence of the user 40 at the user facility 10. The location information may also include information indicating that the user 40 is not present at the user facility 10 and accessing the space 20. The location information may also be determined based on information received from the EMS21 or the user agent 50.

The control part 33 may include at least one processor. At least one processor may be comprised of a single Integrated Circuit (IC) or may be comprised of multiple communicatively coupled circuits (integrated and/or discrete circuits, etc.).

When the user 40 is present in the access space 20, the control unit 33 executes fusion processing for fusing the output power to the access space 20 based on the output power data. Here, the fusion processing is processing for fusing the output power from the user facility 10 to the access space 20, and includes, for example, the following processing.

The fusion process may include a process of supplying power to the user 40 within the access space 20 (hereinafter referred to as a power supply process). Specifically, the electric power is supplied to the user 40 in the access space 20 within a range not exceeding the upper limit of the output power output from the solar battery device 11.

For example, the power supplied to the user 40 in the access space 20 (hereinafter referred to as access destination power consumption) may be subtracted from the output power output from the solar cell device 11 without being loaded by a management entity (hereinafter referred to as management entity) accessing the space 20. In such a case, three parties, that is, the user 40, the power management apparatus 30, and the management entity, may perform the processing for canceling the power consumption of the access destination. That is, on the premise that the output power output from the solar cell device 11 is sold from the user 40 to the power management device 30, the user 40 may purchase the output power corresponding to the access destination power consumption from the management entity after the power management device 30 sells the output power corresponding to the access destination power consumption to the management entity. Here, the amount of electricity purchased by the customer 40 from the management entity may be the same as or smaller than the amount of electricity sold by the customer 40 to the electricity management device 30. The amount of electricity purchased by the management entity from the electricity management device 30 may be different from the amount of electricity sold by the management entity to the user 40.

In the embodiment, the electric power supply process may be a process of charging the EV60 with electric power supplied from the charging station 21. In other words, the access destination consumed power is the power charged from the charging station 21 to the EV 60. In this case, the electric power charged from the charging station 21 to the EV60 may be larger than the electric power that is fused by the fusion process (i.e., the access destination consumed electric power). The amount of difference between the electric power charged from the charging station 21EV60 and the electric power fused by the fusion processing is supplied from the electric power system connected to the charging station 21.

Further, in an embodiment, the right to consume power in addition to the access destination may be transferred from the user 40 to the management entity. The right to consume power in addition to the access destination may include: at least one of the fact that the output power is output from the solar cell device 11 and an environmental added value (e.g., green power certificate) added to the output power.

In this case, the control unit 33 may give a value corresponding to the power fusion to the user 40. For example, the control unit 33 may control the communication unit 31 to transmit the value data to the user medium 50.

For example, the value given to the user 40 may be a value corresponding to at least any one of the right attached to the access destination consumed power and the access destination consumed power. Although not particularly limited, the form of the value may be money or points that can be exchanged with goods, services, or money. The money may be legal currency or virtual currency. Money or points may also be stored as value data (electronic data) on the user medium 50.

The control unit 33 may set a value to be given to the user 40 based on at least one of the destination power consumption and the right to be added to the destination power consumption. For example, the control unit 33 may set a higher value as the access destination power consumption is larger. The control unit 33 may set a higher value as the value added to the environment of the access destination power consumption is higher.

(user media)

The following describes the user agent according to the embodiment. As shown in fig. 4, the user agent 50 includes a communication unit 51, a display unit 52, and a control unit 53.

The communication unit 51 is constituted by a communication module. The communication module can be a wireless communication module conforming to the standards of IEEE802.11a/b/G/n, ZigBee, Wi-SUN, LTE, 5G, 6G and the like, and can also be a wired communication module conforming to the standards of IEEE802.3 and the like.

The communication section 51 may receive output power data from the user facility 10. Data of value (the value data) corresponding to the power fusion may be received from the power management device 30. The communication unit 51 may transmit a prompt requesting power fusion to the charging station 21 or the power management device 30. The communication unit 51 may transmit a prompt indicating that the power fusion is completed to the charging station 21 or the power management device 30.

The display unit 52 includes a panel such as a liquid crystal panel or an organic EL panel. The display unit 52 may include a touch panel.

The display unit 52 may display the output power data. The display unit 52 may display the right to output the electric power. The display unit 52 may display information (for example, the level of the output power or the environmental added value) for setting the content of the right related to the output power. The display unit 52 may display the value given by the fusion processing.

The control section 53 may also include at least one processor. At least one processor may be comprised of a single Integrated Circuit (IC) or may be comprised of multiple communicatively coupled circuits (integrated and/or discrete circuits, etc.).

The control unit 53 may control the image displayed on the display unit 52 based on the information received by the communication unit 51. The control unit 53 may control the communication unit 51 based on a user operation based on the image displayed on the display unit 52.

(Power management method)

Hereinafter, a power management method according to an embodiment will be described.

As shown in fig. 5, in step S11, the user facility 10 transmits the output power data to the power management device 30. For example, the customer facility 10 periodically transmits output power data managed (or stored) by the EMS12 to the power management device 30.

In step S12, the power management device 30 manages the output power data.

In step S13, the user agent 50 transmits a prompt (a fusion request in fig. 5) to request power fusion to the charging station 21. The request for the fusion may include identification information of the user agent 50 or may include location information of the user agent 50.

In step S14, charging station 21 transmits a prompt to request power fusion (fusion request in fig. 5) to power management device 30. The request for the fusion may include identification information of the charging station 21, location information of the charging station 21, identification information of the user agent 50, and location information of the user agent 50.

In step S15, the power management device 30 executes a fusion process of fusing the output power from the user facility 10 to the access space 20. For example, the fusion process is a process of supplying power to the user 40 in the access space 20. For example, as shown in step S16, charging station 21 charges EV60 with electric power that is fused by the fusion process.

In step S17, charging station 21 transmits a prompt that the power fusion has been completed (fusion completion in fig. 5) to power management device 30. The completion of the fusion may include identification information of the charging station 21, location information of the charging station 21, identification information of the user agent 50, and location information of the user agent 50.

In step S18, the power management device 30 sets the value to be given to the user 40, and transmits the value data to the user agent 50. The value setting method is as described above.

In step S17, for example, when the charging completion report, that is, "completion of the financing" is notified from the charging station 21 to the power management device 30, the value data is notified to the user agent 50 in step S18, and as a result, the user can know that the charging is completed.

Before step S17, for example, a charge completion notification may be transmitted from EV60 to charging station 21.

(action and Effect)

In the embodiment, when the user 40 is present in the access space 20, the power management device 30 executes the fusion process of fusing the output power to the access space 20 based on the output power data. Further, the fusion process includes a power supply process. Therefore, the output power output from the solar battery device 11 provided in the user facility 10 can be used as the access destination power consumption in the access space 20, and the user 40 can freely use the output power in the sense that the output power output from the solar battery device 11 is taken out to the access space 20.

Further, it is advantageous for the management entity to perform the fusion processing when the fusion processing includes a shift of the right to consume power in addition to the access destination. For example, by giving value to the user 40 in return for the environmental added value obtained from the user 40, the environmental added value can be contributed as a management entity.

[ modification example 1]

A modified example 1 of the embodiment will be described below. The following description will mainly be made of aspects different from the embodiments.

In an embodiment, EV60 is a private car that user 40 has. In contrast, in modification 1, EV60 is an electric vehicle (so-called shared vehicle) supplied by two or more users.

Specifically, as shown in fig. 6, the output power output from the solar battery device 11 installed in the user facility 10 is compatible with the access space 20, and the EV60 is charged in the access space 20 using the power supplied from the charging station 21. The details of the fusion processing are the same as those of the embodiment.

In this case, the charging station 21 may be provided at a hub (e.g., a parking lot) of the shared vehicle. In this case, the charging station 21 may have a function (for example, user authentication) of executing a process for starting or ending the shared vehicle. Alternatively, the charging station 21 may be installed in a place other than the hub of the shared vehicle. In this case, the charging station 21 may be managed by an operator who is affiliated with an operator who shares cars.

Here, the shared automobile is explained, but the modification 1 is not limited to this. For example, the EV60 may be an electric vehicle (rental car) rented to the user 40 by the operator.

[ modification 2]

A modified example 2 of the embodiment will be described below. The following description will mainly be made of aspects different from the embodiments.

In the embodiment, a case where EV60 is charged in access space 20 is described as an example of the power supply process. In contrast, in modification 2, a case where the access space 20 is a facility other than the user facility 10 will be described.

Specifically, as shown in fig. 7, the access space 20 is an access facility 22 other than the user facility 10. The access facility 22 may be the facility of an acquaintance of the user 40 or the facility (e.g., a company or school) at which the user 40 is at work.

In this case, the fusion processing is processing for fusing the output power output from the solar battery device 11 provided in the consumer facility 10 as the power consumed by the consumer 40 at the visiting facility 22 (i.e., the visiting destination power consumption).

For example, when the power consumption of the access destination cannot be determined, it is considered that all of the output power output from the solar cell device 11 is integrated with the access facility 22 while the user 40 is present at the access facility 22. Alternatively, it is also conceivable that predetermined power included in the output power output from the solar battery device 11 is compatible with the access facility 22. The prescribed power may be defined by a prescribed power or a prescribed ratio with respect to the output power. The electric power integrated with the access facility 22 may be integrated at no cost or at a cost. Further, a value corresponding to the power fusion may be given to the user 40.

Alternatively, when the access destination power consumption can be specified, it is also possible to consider that the power corresponding to the access destination power consumption is integrated with the access facility 22. In this case, the electric power corresponding to the electric power consumed by the access destination may be financed for free or for compensation. Further, a value corresponding to the power fusion may be given to the user 40.

Alternatively, even when the power consumption of the access destination can be specified, it is considered that all of the output power output from the solar battery device 11 is integrated with the access facility 22 while the user 40 is present at the access facility 22. Alternatively, it is also conceivable that predetermined power included in the output power output from the solar battery device 11 is compatible with the access facility 22. The prescribed power may be defined by the prescribed power or by a prescribed ratio with respect to the output power. The electric power integrated with the access facility 22 may be integrated at no cost or at a cost. Alternatively, the electric power corresponding to the visit destination electric power consumption may be integrated at no charge, and the electric power integrated with the visit facility 22 and the differential electric power between the visit destination electric power consumption may be integrated at a charge. Further, a value corresponding to the power fusion may be given to the user 40.

[ modification 3]

A modified example 3 of the embodiment will be described below. The following description will mainly be made of aspects different from the embodiments.

In the embodiment, a case where EV60 is charged in access space 20 is described as an example of the power supply process. In contrast, in modification 3, the access space 20 may be a space inside the mobile body that uses electricity as an energy source.

Specifically, as shown in fig. 8, the access space 20 is a space inside an electric bus 23 that uses electricity as an energy source.

In this case, since the electric bus 23 on which the user 40 sits consumes electric power, a part of the electric power consumed by the electric bus 23 can be considered as electric power consumed by the user 40 on the electric bus 23 (i.e., access destination consumed electric power). That is, the fusion process is a process of fusing the output power output from the solar battery device 11 provided in the user facility 10 as a part of the power consumed by the electric bus 23.

It is also considered that the predetermined power included in the output power output from the solar battery device 11 is compatible with the electric bus 23. The prescribed power may be defined by the prescribed power or by a prescribed ratio with respect to the output power. The amount of money corresponding to the electric power that is fused with the electric bus 23 may be subtracted from the fare of the electric bus 23. Further, a value corresponding to the power fusion may be given to the user 40. In addition, while the user 40 is riding on the electric bus 23, all of the output power output from the solar cell device 11 can be integrated with the electric bus 23.

Here, the mobile body using electricity as an energy source may be a mobile body such as an airplane, a ship, a taxi, and a train, in addition to the electric bus 23.

[ modification 4]

A modified example 4 of the embodiment will be described below. The following description will mainly be made of aspects different from the embodiments.

In the embodiment, the distributed power source is the solar cell device 11. In contrast, in modification 4, the distributed power source may include a power source other than the solar cell device 11.

In modification 4, the distributed power source may include a fuel cell device. Examples of the Fuel Cell device include a Solid Oxide Fuel Cell (SOFC), a Polymer Electrolyte Fuel Cell (PEFC), a Phosphoric Acid Fuel Cell (PAFC), and a Molten Carbonate Fuel Cell (MCFC).

In modification 4, the power generation device that generates power from natural energy may include at least one of a wind power generation device, a geothermal power generation device, and a hydro power generation device. Natural energy sources may also be referred to as renewable energy sources.

In modification 4, two or more distributed power supplies selected from the various distributed power supplies described above may be used. The two or more distributed power sources may include solar cell devices 11.

[ modification 5]

A modified example 5 of the embodiment will be described below. The following description will mainly be made of aspects different from the embodiments.

As described in the embodiment, the user 40 having the distributed power source (the solar battery device 11) is the subject having the right to the output power of the solar battery device 11. In other words, the distributed power source may be owned by the user 40 or leased to the user 40.

In modification 5, a case where the distributed power source (solar cell device 11) is provided by a third party will be described. This may also include ways to debit the user 40 from the distributed power source. Even in this case, since the distributed power supply is provided in the user facility 10, the user 40 may be considered to have the distributed power supply although the user 40 does not own the distributed power supply. Alternatively, since the user 40 has the right to perform the fusion processing of the output power outputted from the distributed power source, it is considered that the user has the distributed power source. For example, the third party may be an operator who uses the power management apparatus 30 described above. Such an operator may also be an operator of a power generation operator, a power transmission and distribution operator, a retailer, or a resource integrator.

In such a case, the third party may also collect a payment (electricity fee) for the power consumed at the customer facility 10 from the customer 40. Further, similarly to the embodiment, the fusion processing may be performed on surplus power obtained by subtracting the power consumption of the customer facility 10 from the power output from the solar battery device 11. As in the embodiment, the value corresponding to the financing process may be given to the user 40. In this case, the third party may receive a reward from the user 40 for the electric power financed by the financing process among the electric powers output from the solar battery device 11.

As described above, when the distributed power source is owned by a third party, the user facility 10 may be a concept including a collective housing made up of two or more residents, a concept including a building in which two or more tenants live, or a concept including a collective housing of facilities connected to the microgrid.

Other embodiments

The present disclosure has been described based on the above-described embodiments, but the discussion and drawings constituting a part of the present disclosure should not be construed as limiting the present disclosure. Various alternative embodiments, examples, and operational techniques will be apparent to those skilled in the art in light of this disclosure.

In an embodiment, the method of assigning value to the user 40 is a method of transmitting value data to the user agent 50. However, the embodiment is not limited thereto. A value corresponding to the fusion process may be given to a device other than the user agent 50. For example, the value may be given as points managed by the management entity. The medium to which value is assigned may be a credit card or loyalty card, or may be a server managed by a management entity. In this case, the power management apparatus 30 may transmit the value data to the management entity. Although not specifically mentioned in the embodiment, the power carrier that manages the user facility 10 may also be different from the power carrier that manages the access space 20. The power operator may be a power generation operator, a power transmission and distribution operator, a retailer, or a resource integrator. A resource integrator is an electric Power provider that provides Power to a Power generation provider, a Power transmission and distribution provider, a retailer, and the like in a VPP (Virtual Power Plant).

Although not specifically mentioned in the embodiment, the electric power may be instantaneous electric power (kW) or may be an accumulated electric power amount (kWh). For example, the output power data may include instantaneous power (kW) and may also include an accumulated amount of power (kWh). The value corresponding to the fusion process may be determined based on the integrated amount of electric power (kWh) of electric power fused by the fusion process.

Although not specifically mentioned in the embodiment, a program that causes a computer to execute each process performed by the power management apparatus 30 or the user agent 50 may be provided. The program may be recorded in a computer-readable medium. If a computer-readable medium is used, a program can be installed in the computer. Here, the computer-readable medium on which the program is recorded may be a non-transitory recording medium. The non-transitory recording medium is not particularly limited, and may be a recording medium such as a CD-ROM or a DVD-ROM.

Alternatively, a chip may be provided that includes a memory for storing a program for executing each process performed by the power management device 30 or the user agent 50, and a processor for executing the program stored in the memory.
